To run multiple applications in an HTML document you must manually bootstrap them using - * {@link angular.bootstrap} instead. - * - AngularJS applications cannot be nested within each other. - * - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`. - * This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and - * {@link ngRoute.ngView `ngView`}. - * Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector}, - * causing animations to stop working and making the injector inaccessible from outside the app. - * - * You can specify an **AngularJS module** to be used as the root module for the application. This - * module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It - * should contain the application code needed or have dependencies on other modules that will - * contain the code. See {@link angular.module} for more information. - * - * In the example below if the `ngApp` directive were not placed on the `html` element then the - * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}` - * would not be resolved to `3`. - * - * @example - * - * ### Simple Usage - * - * `ngApp` is the easiest, and most common way to bootstrap an application. - * - - -

If jQuery is not available, `angular.element` - * delegates to Angular's built-in subset of jQuery, called "jQuery lite" or **jqLite**. - * - * jqLite is a tiny, API-compatible subset of jQuery that allows - * Angular to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most - * commonly needed functionality with the goal of having a very small footprint. - * - * To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the - * {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a - * specific version of jQuery if multiple versions exist on the page. - * - *
**Note:** All element references in Angular are always wrapped with jQuery or - * jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.
- * - *
**Note:** Keep in mind that this function will not find elements - * by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)` - * or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.
- * - * ## Angular's jqLite - * jqLite provides only the following jQuery methods: - * - * - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument - * - [`after()`](http://api.jquery.com/after/) - * - [`append()`](http://api.jquery.com/append/) - * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters - * - [`bind()`](http://api.jquery.com/bind/) (_deprecated_, use [`on()`](http://api.jquery.com/on/)) - Does not support namespaces, selectors or eventData - * - [`children()`](http://api.jquery.com/children/) - Does not support selectors - * - [`clone()`](http://api.jquery.com/clone/) - * - [`contents()`](http://api.jquery.com/contents/) - * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`. - * As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing. - * - [`data()`](http://api.jquery.com/data/) - * - [`detach()`](http://api.jquery.com/detach/) - * - [`empty()`](http://api.jquery.com/empty/) - * - [`eq()`](http://api.jquery.com/eq/) - * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name - * - [`hasClass()`](http://api.jquery.com/hasClass/) - * - [`html()`](http://api.jquery.com/html/) - * - [`next()`](http://api.jquery.com/next/) - Does not support selectors - * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData - * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter - * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors - * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors - * - [`prepend()`](http://api.jquery.com/prepend/) - * - [`prop()`](http://api.jquery.com/prop/) - * - [`ready()`](http://api.jquery.com/ready/) (_deprecated_, use `angular.element(callback)` instead of `angular.element(document).ready(callback)`) - * - [`remove()`](http://api.jquery.com/remove/) - * - [`removeAttr()`](http://api.jquery.com/removeAttr/) - Does not support multiple attributes - * - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument - * - [`removeData()`](http://api.jquery.com/removeData/) - * - [`replaceWith()`](http://api.jquery.com/replaceWith/) - * - [`text()`](http://api.jquery.com/text/) - * - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument - * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers - * - [`unbind()`](http://api.jquery.com/unbind/) (_deprecated_, use [`off()`](http://api.jquery.com/off/)) - Does not support namespaces or event object as parameter - * - [`val()`](http://api.jquery.com/val/) - * - [`wrap()`](http://api.jquery.com/wrap/) - * - * ## jQuery/jqLite Extras - * Angular also provides the following additional methods and events to both jQuery and jqLite: - * - * ### Events - * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event - * on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM - * element before it is removed. - * - * ### Methods - * - `controller(name)` - retrieves the controller of the current element or its parent. By default - * retrieves controller associated with the `ngController` directive. If `name` is provided as - * camelCase directive name, then the controller for this directive will be retrieved (e.g. - * `'ngModel'`). - * - `injector()` - retrieves the injector of the current element or its parent. - * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current - * element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to - * be enabled. - * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the - * current element. This getter should be used only on elements that contain a directive which starts a new isolate - * scope. Calling `scope()` on this element always returns the original non-isolate scope. - * Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled. - * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top - * parent element is reached. - * - * @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x. See - * https://github.com/angular/angular.js/issues/14251 for more information. - * - * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery. - * @returns {Object} jQuery object. - */ - -JQLite.expando = 'ng339'; - -var jqCache = JQLite.cache = {}, - jqId = 1; - -/* - * !!!

- * **Note:** This document is an in-depth reference of all directive options. - * For a gentle introduction to directives with examples of common use cases, - * see the {@link guide/directive directive guide}. - *
- * - * ## Comprehensive Directive API - * - * There are many different options for a directive. - * - * The difference resides in the return value of the factory function. - * You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)} - * that defines the directive properties, or just the `postLink` function (all other properties will have - * the default values). - * - *
- * **Best Practice:** It's recommended to use the "directive definition object" form. - *
- * - * Here's an example directive declared with a Directive Definition Object: - * - * ```js - * var myModule = angular.module(...); - * - * myModule.directive('directiveName', function factory(injectables) { - * var directiveDefinitionObject = { - * {@link $compile#-priority- priority}: 0, - * {@link $compile#-template- template}: '
', // or // function(tElement, tAttrs) { ... }, - * // or - * // {@link $compile#-templateurl- templateUrl}: 'directive.html', // or // function(tElement, tAttrs) { ... }, - * {@link $compile#-transclude- transclude}: false, - * {@link $compile#-restrict- restrict}: 'A', - * {@link $compile#-templatenamespace- templateNamespace}: 'html', - * {@link $compile#-scope- scope}: false, - * {@link $compile#-controller- controller}: function($scope, $element, $attrs, $transclude, otherInjectables) { ... }, - * {@link $compile#-controlleras- controllerAs}: 'stringIdentifier', - * {@link $compile#-bindtocontroller- bindToController}: false, - * {@link $compile#-require- require}: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'], - * {@link $compile#-multielement- multiElement}: false, - * {@link $compile#-compile- compile}: function compile(tElement, tAttrs, transclude) { - * return { - * {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... }, - * {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... } - * } - * // or - * // return function postLink( ... ) { ... } - * }, - * // or - * // {@link $compile#-link- link}: { - * // {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... }, - * // {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... } - * // } - * // or - * // {@link $compile#-link- link}: function postLink( ... ) { ... } - * }; - * return directiveDefinitionObject; - * }); - * ``` - * - *
- * **Note:** Any unspecified options will use the default value. You can see the default values below. - *
- * - * Therefore the above can be simplified as: - * - * ```js - * var myModule = angular.module(...); - * - * myModule.directive('directiveName', function factory(injectables) { - * var directiveDefinitionObject = { - * link: function postLink(scope, iElement, iAttrs) { ... } - * }; - * return directiveDefinitionObject; - * // or - * // return function postLink(scope, iElement, iAttrs) { ... } - * }); - * ``` - * - * ### Life-cycle hooks - * Directive controllers can provide the following methods that are called by Angular at points in the life-cycle of the - * directive: - * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and - * had their bindings initialized (and before the pre & post linking functions for the directives on - * this element). This is a good place to put initialization code for your controller. - * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The - * `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an - * object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a - * component such as cloning the bound value to prevent accidental mutation of the outer value. Note that this will - * also be called when your bindings are initialized. - * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on - * changes. Any actions that you wish to take in response to the changes that you detect must be - * invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook - * could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not - * be detected by Angular's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments; - * if detecting changes, you must store the previous value(s) for comparison to the current values. - * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing - * external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in - * the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent - * components will have their `$onDestroy()` hook called before child components. - * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link - * function this hook can be used to set up DOM event handlers and do direct DOM manipulation. - * Note that child elements that contain `templateUrl` directives will not have been compiled and linked since - * they are waiting for their template to load asynchronously and their own compilation and linking has been - * suspended until that occurs. - * - * #### Comparison with Angular 2 life-cycle hooks - * Angular 2 also uses life-cycle hooks for its components. While the Angular 1 life-cycle hooks are similar there are - * some differences that you should be aware of, especially when it comes to moving your code from Angular 1 to Angular 2: - * - * * Angular 1 hooks are prefixed with `$`, such as `$onInit`. Angular 2 hooks are prefixed with `ng`, such as `ngOnInit`. - * * Angular 1 hooks can be defined on the controller prototype or added to the controller inside its constructor. - * In Angular 2 you can only define hooks on the prototype of the Component class. - * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in Angular 1 than you would to - * `ngDoCheck` in Angular 2 - * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be - * propagated throughout the application. - * Angular 2 does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an - * error or do nothing depending upon the state of `enableProdMode()`. - * - * #### Life-cycle hook examples - * - * This example shows how you can check for mutations to a Date object even though the identity of the object - * has not changed. - * - * - * - * angular.module('do-check-module', []) - * .component('app', { - * template: - * 'Month: ' + - * 'Date: {{ $ctrl.date }}' + - * '', - * controller: function() { - * this.date = new Date(); - * this.month = this.date.getMonth(); - * this.updateDate = function() { - * this.date.setMonth(this.month); - * }; - * } - * }) - * .component('test', { - * bindings: { date: '<' }, - * template: - * '
{{ $ctrl.log | json }}
', - * controller: function() { - * var previousValue; - * this.log = []; - * this.$doCheck = function() { - * var currentValue = this.date && this.date.valueOf(); - * if (previousValue !== currentValue) { - * this.log.push('doCheck: date mutated: ' + this.date); - * previousValue = currentValue; - * } - * }; - * } - * }); - * - * - * - * - * - * - * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the - * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large - * arrays or objects can have a negative impact on your application performance) - * - * - * - *

- * - * - * angular.module('do-check-module', []) - * .component('test', { - * bindings: { items: '<' }, - * template: - * '

The attributes are: - * - * #### `multiElement` - * When this property is set to true (default is `false`), the HTML compiler will collect DOM nodes between - * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them - * together as the directive elements. It is recommended that this feature be used on directives - * which are not strictly behavioral (such as {@link ngClick}), and which - * do not manipulate or replace child nodes (such as {@link ngInclude}). - * - * #### `priority` - * When there are multiple directives defined on a single DOM element, sometimes it - * is necessary to specify the order in which the directives are applied. The `priority` is used - * to sort the directives before their `compile` functions get called. Priority is defined as a - * number. Directives with greater numerical `priority` are compiled first. Pre-link functions - * are also run in priority order, but post-link functions are run in reverse order. The order - * of directives with the same priority is undefined. The default priority is `0`. - * - * #### `terminal` - * If set to true then the current `priority` will be the last set of directives - * which will execute (any directives at the current priority will still execute - * as the order of execution on same `priority` is undefined). Note that expressions - * and other directives used in the directive's template will also be excluded from execution. - * - * #### `scope` - * The scope property can be `false`, `true`, or an object: - * - * * **`false` (default):** No scope will be created for the directive. The directive will use its - * parent's scope. - * - * * **`true`:** A new child scope that prototypically inherits from its parent will be created for - * the directive's element. If multiple directives on the same element request a new scope, - * only one new scope is created. - * - * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's template. - * The 'isolate' scope differs from normal scope in that it does not prototypically - * inherit from its parent scope. This is useful when creating reusable components, which should not - * accidentally read or modify data in the parent scope. Note that an isolate scope - * directive without a `template` or `templateUrl` will not apply the isolate scope - * to its children elements. - * - * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the - * directive's element. These local properties are useful for aliasing values for templates. The keys in - * the object hash map to the name of the property on the isolate scope; the values define how the property - * is bound to the parent scope, via matching attributes on the directive's element: - * - * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is - * always a string since DOM attributes are strings. If no `attr` name is specified then the - * attribute name is assumed to be the same as the local name. Given `` and the isolate scope definition `scope: { localName:'@myAttr' }`, - * the directive's scope property `localName` will reflect the interpolated value of `hello - * {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's - * scope. The `name` is read from the parent scope (not the directive's scope). - * - * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression - * passed via the attribute `attr`. The expression is evaluated in the context of the parent scope. - * If no `attr` name is specified then the attribute name is assumed to be the same as the local - * name. Given `` and the isolate scope definition `scope: { - * localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the - * value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in - * `localModel` and vice versa. Optional attributes should be marked as such with a question mark: - * `=?` or `=?attr`. If the binding expression is non-assignable, or if the attribute isn't - * optional and doesn't exist, an exception ({@link error/$compile/nonassign `$compile:nonassign`}) - * will be thrown upon discovering changes to the local value, since it will be impossible to sync - * them back to the parent scope. By default, the {@link ng.$rootScope.Scope#$watch `$watch`} - * method is used for tracking changes, and the equality check is based on object identity. - * However, if an object literal or an array literal is passed as the binding expression, the - * equality check is done by value (using the {@link angular.equals} function). It's also possible - * to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection - * `$watchCollection`}: use `=*` or `=*attr` (`=*?` or `=*?attr` if the attribute is optional). - * - * * `<` or `` and directive definition of - * `scope: { localModel:'` and the isolate scope definition `scope: { - * localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for - * the `count = count + value` expression. Often it's desirable to pass data from the isolated scope - * via an expression to the parent scope. This can be done by passing a map of local variable names - * and values into the expression wrapper fn. For example, if the expression is `increment(amount)` - * then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`. - * - * In general it's possible to apply more than one directive to one element, but there might be limitations - * depending on the type of scope required by the directives. The following points will help explain these limitations. - * For simplicity only two directives are taken into account, but it is also applicable for several directives: - * - * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope - * * **child scope** + **no scope** => Both directives will share one single child scope - * * **child scope** + **child scope** => Both directives will share one single child scope - * * **isolated scope** + **no scope** => The isolated directive will use it's own created isolated scope. The other directive will use - * its parent's scope - * * **isolated scope** + **child scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives cannot - * be applied to the same element. - * * **isolated scope** + **isolated scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives - * cannot be applied to the same element. - * - * - * #### `bindToController` - * This property is used to bind scope properties directly to the controller. It can be either - * `true` or an object hash with the same format as the `scope` property. - * - * When an isolate scope is used for a directive (see above), `bindToController: true` will - * allow a component to have its properties bound to the controller, rather than to scope. - * - * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller - * properties. You can access these bindings once they have been initialized by providing a controller method called - * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings - * initialized. - * - *
- * **Deprecation warning:** if `$compileProcvider.preAssignBindingsEnabled(true)` was called, bindings for non-ES6 class - * controllers are bound to `this` before the controller constructor is called but this use is now deprecated. Please - * place initialization code that relies upon bindings inside a `$onInit` method on the controller, instead. - *
- * - * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property. - * This will set up the scope bindings to the controller directly. Note that `scope` can still be used - * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate - * scope (useful for component directives). - * - * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`. - * - * - * #### `controller` - * Controller constructor function. The controller is instantiated before the - * pre-linking phase and can be accessed by other directives (see - * `require` attribute). This allows the directives to communicate with each other and augment - * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals: - * - * * `$scope` - Current scope associated with the element - * * `$element` - Current element - * * `$attrs` - Current attributes object for the element - * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope: - * `function([scope], cloneLinkingFn, futureParentElement, slotName)`: - * * `scope`: (optional) override the scope. - * * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content. - * * `futureParentElement` (optional): - * * defines the parent to which the `cloneLinkingFn` will add the cloned elements. - * * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`. - * * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements) - * and when the `cloneLinkingFn` is passed, - * as those elements need to created and cloned in a special way when they are defined outside their - * usual containers (e.g. like ``). - * * See also the `directive.templateNamespace` property. - * * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`) - * then the default transclusion is provided. - * The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns - * `true` if the specified slot contains content (i.e. one or more DOM nodes). - * - * #### `require` - * Require another directive and inject its controller as the fourth argument to the linking function. The - * `require` property can be a string, an array or an object: - * * a **string** containing the name of the directive to pass to the linking function - * * an **array** containing the names of directives to pass to the linking function. The argument passed to the - * linking function will be an array of controllers in the same order as the names in the `require` property - * * an **object** whose property values are the names of the directives to pass to the linking function. The argument - * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding - * controllers. - * - * If the `require` property is an object and `bindToController` is truthy, then the required controllers are - * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers - * have been constructed but before `$onInit` is called. - * If the name of the required controller is the same as the local name (the key), the name can be - * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`. - * See the {@link $compileProvider#component} helper for an example of how this can be used. - * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is - * raised (unless no link function is specified and the required controllers are not being bound to the directive - * controller, in which case error checking is skipped). The name can be prefixed with: - * - * * (no prefix) - Locate the required controller on the current element. Throw an error if not found. - * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found. - * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found. - * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found. - * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass - * `null` to the `link` fn if not found. - * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass - * `null` to the `link` fn if not found. - * - * - * #### `controllerAs` - * Identifier name for a reference to the controller in the directive's scope. - * This allows the controller to be referenced from the directive template. This is especially - * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible - * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the - * `controllerAs` reference might overwrite a property that already exists on the parent scope. - * - * - * #### `restrict` - * String of subset of `EACM` which restricts the directive to a specific directive - * declaration style. If omitted, the defaults (elements and attributes) are used. - * - * * `E` - Element name (default): `` - * * `A` - Attribute (default): `
` - * * `C` - Class: `
` - * * `M` - Comment: `` - * - * - * #### `templateNamespace` - * String representing the document type used by the markup in the template. - * AngularJS needs this information as those elements need to be created and cloned - * in a special way when they are defined outside their usual containers like `` and ``. - * - * * `html` - All root nodes in the template are HTML. Root nodes may also be - * top-level elements such as `` or ``. - * * `svg` - The root nodes in the template are SVG elements (excluding ``). - * * `math` - The root nodes in the template are MathML elements (excluding ``). - * - * If no `templateNamespace` is specified, then the namespace is considered to be `html`. - * - * #### `template` - * HTML markup that may: - * * Replace the contents of the directive's element (default). - * * Replace the directive's element itself (if `replace` is true - DEPRECATED). - * * Wrap the contents of the directive's element (if `transclude` is true). - * - * Value may be: - * - * * A string. For example `
{{delete_str}}
`. - * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile` - * function api below) and returns a string value. - * - * - * #### `templateUrl` - * This is similar to `template` but the template is loaded from the specified URL, asynchronously. - * - * Because template loading is asynchronous the compiler will suspend compilation of directives on that element - * for later when the template has been resolved. In the meantime it will continue to compile and link - * sibling and parent elements as though this element had not contained any directives. - * - * The compiler does not suspend the entire compilation to wait for templates to be loaded because this - * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the - * case when only one deeply nested directive has `templateUrl`. - * - * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache} - * - * You can specify `templateUrl` as a string representing the URL or as a function which takes two - * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns - * a string value representing the url. In either case, the template URL is passed through {@link - * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}. - * - * - * #### `replace` (*DEPRECATED*) - * - * `replace` will be removed in next major release - i.e. v2.0). - * - * Specifies what the template should replace. Defaults to `false`. - * - * * `true` - the template will replace the directive's element. - * * `false` - the template will replace the contents of the directive's element. - * - * The replacement process migrates all of the attributes / classes from the old element to the new - * one. See the {@link guide/directive#template-expanding-directive - * Directives Guide} for an example. - * - * There are very few scenarios where element replacement is required for the application function, - * the main one being reusable custom components that are used within SVG contexts - * (because SVG doesn't work with custom elements in the DOM tree). - * - * #### `transclude` - * Extract the contents of the element where the directive appears and make it available to the directive. - * The contents are compiled and provided to the directive as a **transclusion function**. See the - * {@link $compile#transclusion Transclusion} section below. - * - * - * #### `compile` - * - * ```js - * function compile(tElement, tAttrs, transclude) { ... } - * ``` - * - * The compile function deals with transforming the template DOM. Since most directives do not do - * template transformation, it is not used often. The compile function takes the following arguments: - * - * * `tElement` - template element - The element where the directive has been declared. It is - * safe to do template transformation on the element and child elements only. - * - * * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared - * between all directive compile functions. - * - * * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)` - * - *
- * **Note:** The template instance and the link instance may be different objects if the template has - * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that - * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration - * should be done in a linking function rather than in a compile function. - *
- - *
- * **Note:** The compile function cannot handle directives that recursively use themselves in their - * own templates or compile functions. Compiling these directives results in an infinite loop and - * stack overflow errors. - * - * This can be avoided by manually using $compile in the postLink function to imperatively compile - * a directive's template instead of relying on automatic template compilation via `template` or - * `templateUrl` declaration or manual compilation inside the compile function. - *
- * - *
- * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it - * e.g. does not know about the right outer scope. Please use the transclude function that is passed - * to the link function instead. - *
- - * A compile function can have a return value which can be either a function or an object. - * - * * returning a (post-link) function - is equivalent to registering the linking function via the - * `link` property of the config object when the compile function is empty. - * - * * returning an object with function(s) registered via `pre` and `post` properties - allows you to - * control when a linking function should be called during the linking phase. See info about - * pre-linking and post-linking functions below. - * - * - * #### `link` - * This property is used only if the `compile` property is not defined. - * - * ```js - * function link(scope, iElement, iAttrs, controller, transcludeFn) { ... } - * ``` - * - * The link function is responsible for registering DOM listeners as well as updating the DOM. It is - * executed after the template has been cloned. This is where most of the directive logic will be - * put. - * - * * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the - * directive for registering {@link ng.$rootScope.Scope#$watch watches}. - * - * * `iElement` - instance element - The element where the directive is to be used. It is safe to - * manipulate the children of the element only in `postLink` function since the children have - * already been linked. - * - * * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared - * between all directive linking functions. - * - * * `controller` - the directive's required controller instance(s) - Instances are shared - * among all directives, which allows the directives to use the controllers as a communication - * channel. The exact value depends on the directive's `require` property: - * * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one - * * `string`: the controller instance - * * `array`: array of controller instances - * - * If a required controller cannot be found, and it is optional, the instance is `null`, - * otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown. - * - * Note that you can also require the directive's own controller - it will be made available like - * any other controller. - * - * * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope. - * This is the same as the `$transclude` parameter of directive controllers, - * see {@link ng.$compile#-controller- the controller section for details}. - * `function([scope], cloneLinkingFn, futureParentElement)`. - * - * #### Pre-linking function - * - * Executed before the child elements are linked. Not safe to do DOM transformation since the - * compiler linking function will fail to locate the correct elements for linking. - * - * #### Post-linking function - * - * Executed after the child elements are linked. - * - * Note that child elements that contain `templateUrl` directives will not have been compiled - * and linked since they are waiting for their template to load asynchronously and their own - * compilation and linking has been suspended until that occurs. - * - * It is safe to do DOM transformation in the post-linking function on elements that are not waiting - * for their async templates to be resolved. - * - * - * ### Transclusion - * - * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and - * copying them to another part of the DOM, while maintaining their connection to the original AngularJS - * scope from where they were taken. - * - * Transclusion is used (often with {@link ngTransclude}) to insert the - * original contents of a directive's element into a specified place in the template of the directive. - * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded - * content has access to the properties on the scope from which it was taken, even if the directive - * has isolated scope. - * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}. - * - * This makes it possible for the widget to have private state for its template, while the transcluded - * content has access to its originating scope. - * - *
- * **Note:** When testing an element transclude directive you must not place the directive at the root of the - * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives - * Testing Transclusion Directives}. - *
- * - * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the - * directive's element, the entire element or multiple parts of the element contents: - * - * * `true` - transclude the content (i.e. the child nodes) of the directive's element. - * * `'element'` - transclude the whole of the directive's element including any directives on this - * element that defined at a lower priority than this directive. When used, the `template` - * property is ignored. - * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template. - * - * **Mult-slot transclusion** is declared by providing an object for the `transclude` property. - * - * This object is a map where the keys are the name of the slot to fill and the value is an element selector - * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`) - * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc). - * - * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives} - * - * If the element selector is prefixed with a `?` then that slot is optional. - * - * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `` elements to - * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive. - * - * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements - * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call - * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and - * injectable into the directive's controller. - * - * - * #### Transclusion Functions - * - * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion - * function** to the directive's `link` function and `controller`. This transclusion function is a special - * **linking function** that will return the compiled contents linked to a new transclusion scope. - * - *
- * If you are just using {@link ngTransclude} then you don't need to worry about this function, since - * ngTransclude will deal with it for us. - *
- * - * If you want to manually control the insertion and removal of the transcluded content in your directive - * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery - * object that contains the compiled DOM, which is linked to the correct transclusion scope. - * - * When you call a transclusion function you can pass in a **clone attach function**. This function accepts - * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded - * content and the `scope` is the newly created transclusion scope, which the clone will be linked to. - * - *
- * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function - * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope. - *
- * - * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone - * attach function**: - * - * ```js - * var transcludedContent, transclusionScope; - * - * $transclude(function(clone, scope) { - * element.append(clone); - * transcludedContent = clone; - * transclusionScope = scope; - * }); - * ``` - * - * Later, if you want to remove the transcluded content from your DOM then you should also destroy the - * associated transclusion scope: - * - * ```js - * transcludedContent.remove(); - * transclusionScope.$destroy(); - * ``` - * - *
- * **Best Practice**: if you intend to add and remove transcluded content manually in your directive - * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it), - * then you are also responsible for calling `$destroy` on the transclusion scope. - *
- * - * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat} - * automatically destroy their transcluded clones as necessary so you do not need to worry about this if - * you are simply using {@link ngTransclude} to inject the transclusion into your directive. - * - * - * #### Transclusion Scopes - * - * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion - * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed - * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it - * was taken. - * - * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look - * like this: - * - * ```html - *
- *
- *
- *
- *
- *
- * ``` - * - * The `$parent` scope hierarchy will look like this: - * - ``` - - $rootScope - - isolate - - transclusion - ``` - * - * but the scopes will inherit prototypically from different scopes to their `$parent`. - * - ``` - - $rootScope - - transclusion - - isolate - ``` - * - * - * ### Attributes - * - * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the - * `link()` or `compile()` functions. It has a variety of uses. - * - * * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways: - * 'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access - * to the attributes. - * - * * *Directive inter-communication:* All directives share the same instance of the attributes - * object which allows the directives to use the attributes object as inter directive - * communication. - * - * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object - * allowing other directives to read the interpolated value. - * - * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes - * that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also - * the only way to easily get the actual value because during the linking phase the interpolation - * hasn't been evaluated yet and so the value is at this time set to `undefined`. - * - * ```js - * function linkingFn(scope, elm, attrs, ctrl) { - * // get the attribute value - * console.log(attrs.ngModel); - * - * // change the attribute - * attrs.$set('ngModel', 'new value'); - * - * // observe changes to interpolated attribute - * attrs.$observe('ngModel', function(value) { - * console.log('ngModel has changed value to ' + value); - * }); - * } - * ``` - * - * ## Example - * - *
- * **Note**: Typically directives are registered with `module.directive`. The example below is - * to illustrate how `$compile` works. - *
- * - - - -
-
-
-
-
- - - it('should auto compile', function() { - var textarea = $('textarea'); - var output = $('div[compile]'); - // The initial state reads 'Hello Angular'. - expect(output.getText()).toBe('Hello Angular'); - textarea.clear(); - textarea.sendKeys('{{name}}!'); - expect(output.getText()).toBe('Angular!'); - }); - - - - * - * - * @param {string|DOMElement} element Element or HTML string to compile into a template function. - * @param {function(angular.Scope, cloneAttachFn=)} transclude function available to directives - DEPRECATED. - * - *
- * **Note:** Passing a `transclude` function to the $compile function is deprecated, as it - * e.g. will not use the right outer scope. Please pass the transclude function as a - * `parentBoundTranscludeFn` to the link function instead. - *
- * - * @param {number} maxPriority only apply directives lower than given priority (Only effects the - * root element(s), not their children) - * @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template - * (a DOM element/tree) to a scope. Where: - * - * * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to. - * * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the - * `template` and call the `cloneAttachFn` function allowing the caller to attach the - * cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is - * called as:
`cloneAttachFn(clonedElement, scope)` where: - * - * * `clonedElement` - is a clone of the original `element` passed into the compiler. - * * `scope` - is the current scope with which the linking function is working with. - * - * * `options` - An optional object hash with linking options. If `options` is provided, then the following - * keys may be used to control linking behavior: - * - * * `parentBoundTranscludeFn` - the transclude function made available to - * directives; if given, it will be passed through to the link functions of - * directives found in `element` during compilation. - * * `transcludeControllers` - an object hash with keys that map controller names - * to a hash with the key `instance`, which maps to the controller instance; - * if given, it will make the controllers available to directives on the compileNode: - * ``` - * { - * parent: { - * instance: parentControllerInstance - * } - * } - * ``` - * * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add - * the cloned elements; only needed for transcludes that are allowed to contain non html - * elements (e.g. SVG elements). See also the directive.controller property. - * - * Calling the linking function returns the element of the template. It is either the original - * element passed in, or the clone of the element if the `cloneAttachFn` is provided. - * - * After linking the view is not updated until after a call to $digest which typically is done by - * Angular automatically. - * - * If you need access to the bound view, there are two ways to do it: - * - * - If you are not asking the linking function to clone the template, create the DOM element(s) - * before you send them to the compiler and keep this reference around. - * ```js - * var element = $compile('

{{total}}

')(scope); - * ``` - * - * - if on the other hand, you need the element to be cloned, the view reference from the original - * example would not point to the clone, but rather to the original template that was cloned. In - * this case, you can access the clone via the cloneAttachFn: - * ```js - * var templateElement = angular.element('

{{total}}

While for simple usage patterns this doesn't matter much, for advanced usage - * it is important to familiarize yourself with these APIs and the guarantees they provide. - * - * - * ## General usage - * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} — - * that is used to generate an HTTP request and returns a {@link ng.$q promise}. - * - * ```js - * // Simple GET request example: - * $http({ - * method: 'GET', - * url: '/someUrl' - * }).then(function successCallback(response) { - * // this callback will be called asynchronously - * // when the response is available - * }, function errorCallback(response) { - * // called asynchronously if an error occurs - * // or server returns response with an error status. - * }); - * ``` - * - * The response object has these properties: - * - * - **data** – `{string|Object}` – The response body transformed with the transform - * functions. - * - **status** – `{number}` – HTTP status code of the response. - * - **headers** – `{function([headerName])}` – Header getter function. - * - **config** – `{Object}` – The configuration object that was used to generate the request. - * - **statusText** – `{string}` – HTTP status text of the response. - * - **xhrStatus** – `{string}` – Status of the XMLHttpRequest (`complete`, `error`, `timeout` or `abort`). - * - * A response status code between 200 and 299 is considered a success status and will result in - * the success callback being called. Any response status code outside of that range is - * considered an error status and will result in the error callback being called. - * Also, status codes less than -1 are normalized to zero. -1 usually means the request was - * aborted, e.g. using a `config.timeout`. - * Note that if the response is a redirect, XMLHttpRequest will transparently follow it, meaning - * that the outcome (success or error) will be determined by the final response status code. - * - * - * ## Shortcut methods - * - * Shortcut methods are also available. All shortcut methods require passing in the URL, and - * request data must be passed in for POST/PUT requests. An optional config can be passed as the - * last argument. - * - * ```js - * $http.get('/someUrl', config).then(successCallback, errorCallback); - * $http.post('/someUrl', data, config).then(successCallback, errorCallback); - * ``` - * - * Complete list of shortcut methods: - * - * - {@link ng.$http#get $http.get} - * - {@link ng.$http#head $http.head} - * - {@link ng.$http#post $http.post} - * - {@link ng.$http#put $http.put} - * - {@link ng.$http#delete $http.delete} - * - {@link ng.$http#jsonp $http.jsonp} - * - {@link ng.$http#patch $http.patch} - * - * - * ## Writing Unit Tests that use $http - * When unit testing (using {@link ngMock ngMock}), it is necessary to call - * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending - * request using trained responses. - * - * ``` - * $httpBackend.expectGET(...); - * $http.get(...); - * $httpBackend.flush(); - * ``` - * - * ## Setting HTTP Headers - * - * The $http service will automatically add certain HTTP headers to all requests. These defaults - * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration - * object, which currently contains this default configuration: - * - * - `$httpProvider.defaults.headers.common` (headers that are common for all requests): - * - Accept: application/json, text/plain, \*/\* - * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests) - * - `Content-Type: application/json` - * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests) - * - `Content-Type: application/json` - * - * To add or overwrite these defaults, simply add or remove a property from these configuration - * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object - * with the lowercased HTTP method name as the key, e.g. - * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`. - * - * The defaults can also be set at runtime via the `$http.defaults` object in the same - * fashion. For example: - * - * ``` - * module.run(function($http) { - * $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w'; - * }); - * ``` - * - * In addition, you can supply a `headers` property in the config object passed when - * calling `$http(config)`, which overrides the defaults without changing them globally. - * - * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis, - * Use the `headers` property, setting the desired header to `undefined`. For example: - * - * ```js - * var req = { - * method: 'POST', - * url: 'http://example.com', - * headers: { - * 'Content-Type': undefined - * }, - * data: { test: 'test' } - * } - * - * $http(req).then(function(){...}, function(){...}); - * ``` - * - * ## Transforming Requests and Responses - * - * Both requests and responses can be transformed using transformation functions: `transformRequest` - * and `transformResponse`. These properties can be a single function that returns - * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions, - * which allows you to `push` or `unshift` a new transformation function into the transformation chain. - * - *
- * **Note:** Angular does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline. - * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference). - * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest - * function will be reflected on the scope and in any templates where the object is data-bound. - * To prevent this, transform functions should have no side-effects. - * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return. - *
- * - * ### Default Transformations - * - * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and - * `defaults.transformResponse` properties. If a request does not provide its own transformations - * then these will be applied. - * - * You can augment or replace the default transformations by modifying these properties by adding to or - * replacing the array. - * - * Angular provides the following default transformations: - * - * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`) is - * an array with one function that does the following: - * - * - If the `data` property of the request configuration object contains an object, serialize it - * into JSON format. - * - * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`) is - * an array with one function that does the following: - * - * - If XSRF prefix is detected, strip it (see Security Considerations section below). - * - If the `Content-Type` is `application/json` or the response looks like JSON, - * deserialize it using a JSON parser. - * - * - * ### Overriding the Default Transformations Per Request - * - * If you wish to override the request/response transformations only for a single request then provide - * `transformRequest` and/or `transformResponse` properties on the configuration object passed - * into `$http`. - * - * Note that if you provide these properties on the config object the default transformations will be - * overwritten. If you wish to augment the default transformations then you must include them in your - * local transformation array. - * - * The following code demonstrates adding a new response transformation to be run after the default response - * transformations have been run. - * - * ```js - * function appendTransform(defaults, transform) { - * - * // We can't guarantee that the default transformation is an array - * defaults = angular.isArray(defaults) ? defaults : [defaults]; - * - * // Append the new transformation to the defaults - * return defaults.concat(transform); - * } - * - * $http({ - * url: '...', - * method: 'GET', - * transformResponse: appendTransform($http.defaults.transformResponse, function(value) { - * return doTransform(value); - * }) - * }); - * ``` - * - * - * ## Caching - * - * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must - * set the config.cache value or the default cache value to TRUE or to a cache object (created - * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes - * precedence over the default cache value. - * - * In order to: - * * cache all responses - set the default cache value to TRUE or to a cache object - * * cache a specific response - set config.cache value to TRUE or to a cache object - * - * If caching is enabled, but neither the default cache nor config.cache are set to a cache object, - * then the default `$cacheFactory("$http")` object is used. - * - * The default cache value can be set by updating the - * {@link ng.$http#defaults `$http.defaults.cache`} property or the - * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property. - * - * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using - * the relevant cache object. The next time the same request is made, the response is returned - * from the cache without sending a request to the server. - * - * Take note that: - * - * * Only GET and JSONP requests are cached. - * * The cache key is the request URL including search parameters; headers are not considered. - * * Cached responses are returned asynchronously, in the same way as responses from the server. - * * If multiple identical requests are made using the same cache, which is not yet populated, - * one request will be made to the server and remaining requests will return the same response. - * * A cache-control header on the response does not affect if or how responses are cached. - * - * - * ## Interceptors - * - * Before you start creating interceptors, be sure to understand the - * {@link ng.$q $q and deferred/promise APIs}. - * - * For purposes of global error handling, authentication, or any kind of synchronous or - * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be - * able to intercept requests before they are handed to the server and - * responses before they are handed over to the application code that - * initiated these requests. The interceptors leverage the {@link ng.$q - * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing. - * - * The interceptors are service factories that are registered with the `$httpProvider` by - * adding them to the `$httpProvider.interceptors` array. The factory is called and - * injected with dependencies (if specified) and returns the interceptor. - * - * There are two kinds of interceptors (and two kinds of rejection interceptors): - * - * * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to - * modify the `config` object or create a new one. The function needs to return the `config` - * object directly, or a promise containing the `config` or a new `config` object. - * * `requestError`: interceptor gets called when a previous interceptor threw an error or - * resolved with a rejection. - * * `response`: interceptors get called with http `response` object. The function is free to - * modify the `response` object or create a new one. The function needs to return the `response` - * object directly, or as a promise containing the `response` or a new `response` object. - * * `responseError`: interceptor gets called when a previous interceptor threw an error or - * resolved with a rejection. - * - * - * ```js - * // register the interceptor as a service - * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) { - * return { - * // optional method - * 'request': function(config) { - * // do something on success - * return config; - * }, - * - * // optional method - * 'requestError': function(rejection) { - * // do something on error - * if (canRecover(rejection)) { - * return responseOrNewPromise - * } - * return $q.reject(rejection); - * }, - * - * - * - * // optional method - * 'response': function(response) { - * // do something on success - * return response; - * }, - * - * // optional method - * 'responseError': function(rejection) { - * // do something on error - * if (canRecover(rejection)) { - * return responseOrNewPromise - * } - * return $q.reject(rejection); - * } - * }; - * }); - * - * $httpProvider.interceptors.push('myHttpInterceptor'); - * - * - * // alternatively, register the interceptor via an anonymous factory - * $httpProvider.interceptors.push(function($q, dependency1, dependency2) { - * return { - * 'request': function(config) { - * // same as above - * }, - * - * 'response': function(response) { - * // same as above - * } - * }; - * }); - * ``` - * - * ## Security Considerations - * - * When designing web applications, consider security threats from: - * - * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) - * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) - * - * Both server and the client must cooperate in order to eliminate these threats. Angular comes - * pre-configured with strategies that address these issues, but for this to work backend server - * cooperation is required. - * - * ### JSON Vulnerability Protection - * - * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) - * allows third party website to turn your JSON resource URL into - * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To - * counter this your server can prefix all JSON requests with following string `")]}',\n"`. - * Angular will automatically strip the prefix before processing it as JSON. - * - * For example if your server needs to return: - * ```js - * ['one','two'] - * ``` - * - * which is vulnerable to attack, your server can return: - * ```js - * )]}', - * ['one','two'] - * ``` - * - * Angular will strip the prefix, before processing the JSON. - * - * - * ### Cross Site Request Forgery (XSRF) Protection - * - * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by - * which the attacker can trick an authenticated user into unknowingly executing actions on your - * website. Angular provides a mechanism to counter XSRF. When performing XHR requests, the - * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP - * header (`X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read the - * cookie, your server can be assured that the XHR came from JavaScript running on your domain. - * The header will not be set for cross-domain requests. - * - * To take advantage of this, your server needs to set a token in a JavaScript readable session - * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the - * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure - * that only JavaScript running on your domain could have sent the request. The token must be - * unique for each user and must be verifiable by the server (to prevent the JavaScript from - * making up its own tokens). We recommend that the token is a digest of your site's - * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography)) - * for added security. - * - * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName - * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time, - * or the per-request config object. - * - * In order to prevent collisions in environments where multiple Angular apps share the - * same domain or subdomain, we recommend that each application uses unique cookie name. - * - * @param {object} config Object describing the request to be made and how it should be - * processed. The object has following properties: - * - * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc) - * - **url** – `{string|TrustedObject}` – Absolute or relative URL of the resource that is being requested; - * or an object created by a call to `$sce.trustAsResourceUrl(url)`. - * - **params** – `{Object.}` – Map of strings or objects which will be serialized - * with the `paramSerializer` and appended as GET parameters. - * - **data** – `{string|Object}` – Data to be sent as the request message data. - * - **headers** – `{Object}` – Map of strings or functions which return strings representing - * HTTP headers to send to the server. If the return value of a function is null, the - * header will not be sent. Functions accept a config object as an argument. - * - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object. - * To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`. - * The handler will be called in the context of a `$apply` block. - * - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload - * object. To bind events to the XMLHttpRequest object, use `eventHandlers`. - * The handler will be called in the context of a `$apply` block. - * - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token. - * - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token. - * - **transformRequest** – - * `{function(data, headersGetter)|Array.}` – - * transform function or an array of such functions. The transform function takes the http - * request body and headers and returns its transformed (typically serialized) version. - * See {@link ng.$http#overriding-the-default-transformations-per-request - * Overriding the Default Transformations} - * - **transformResponse** – - * `{function(data, headersGetter, status)|Array.}` – - * transform function or an array of such functions. The transform function takes the http - * response body, headers and status and returns its transformed (typically deserialized) version. - * See {@link ng.$http#overriding-the-default-transformations-per-request - * Overriding the Default Transformations} - * - **paramSerializer** - `{string|function(Object):string}` - A function used to - * prepare the string representation of request parameters (specified as an object). - * If specified as string, it is interpreted as function registered with the - * {@link $injector $injector}, which means you can create your own serializer - * by registering it as a {@link auto.$provide#service service}. - * The default serializer is the {@link $httpParamSerializer $httpParamSerializer}; - * alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike} - * - **cache** – `{boolean|Object}` – A boolean value or object created with - * {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response. - * See {@link $http#caching $http Caching} for more information. - * - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise} - * that should abort the request when resolved. - * - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the - * XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials) - * for more information. - * - **responseType** - `{string}` - see - * [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype). - * - * @returns {HttpPromise} Returns a {@link ng.$q `Promise}` that will be resolved to a response object - * when the request succeeds or fails. - * - * - * @property {Array.} pendingRequests Array of config objects for currently pending - * requests.

So, for HTML elements interpolated - * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter - * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such, - * this is typically useful only when user-data is used in rendering a template from the server, or - * when otherwise untrusted data is used by a directive. - * - * - * - *

- * - * - * - * @knownIssue - * It is currently not possible for an interpolated expression to contain the interpolation end - * symbol. For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e. - * an interpolated expression consisting of a single-quote (`'`) and the `' }}` string. - * - * @knownIssue - * All directives and components must use the standard `{{` `}}` interpolation symbols - * in their templates. If you change the application interpolation symbols the {@link $compile} - * service will attempt to denormalize the standard symbols to the custom symbols. - * The denormalization process is not clever enough to know not to replace instances of the standard - * symbols where they would not normally be treated as interpolation symbols. For example in the following - * code snippet the closing braces of the literal object will get incorrectly denormalized: - * - * ``` - *

This is similar to the native Promise implementation from ES6, - * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise). - * - * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are - * available yet. - * - * It can be used like so: - * - * ```js - * // for the purpose of this example let's assume that variables `$q` and `okToGreet` - * // are available in the current lexical scope (they could have been injected or passed in). - * - * function asyncGreet(name) { - * // perform some asynchronous operation, resolve or reject the promise when appropriate. - * return $q(function(resolve, reject) { - * setTimeout(function() { - * if (okToGreet(name)) { - * resolve('Hello, ' + name + '!'); - * } else { - * reject('Greeting ' + name + ' is not allowed.'); - * } - * }, 1000); - * }); - * } - * - * var promise = asyncGreet('Robin Hood'); - * promise.then(function(greeting) { - * alert('Success: ' + greeting); - * }, function(reason) { - * alert('Failed: ' + reason); - * }); - * ``` - * - * Note: progress/notify callbacks are not currently supported via the ES6-style interface. - * - * Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise. - * - * However, the more traditional CommonJS-style usage is still available, and documented below. - * - * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an - * interface for interacting with an object that represents the result of an action that is - * performed asynchronously, and may or may not be finished at any given point in time. - * - * From the perspective of dealing with error handling, deferred and promise APIs are to - * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming. - * - * ```js - * // for the purpose of this example let's assume that variables `$q` and `okToGreet` - * // are available in the current lexical scope (they could have been injected or passed in). - * - * function asyncGreet(name) { - * var deferred = $q.defer(); - * - * setTimeout(function() { - * deferred.notify('About to greet ' + name + '.'); - * - * if (okToGreet(name)) { - * deferred.resolve('Hello, ' + name + '!'); - * } else { - * deferred.reject('Greeting ' + name + ' is not allowed.'); - * } - * }, 1000); - * - * return deferred.promise; - * } - * - * var promise = asyncGreet('Robin Hood'); - * promise.then(function(greeting) { - * alert('Success: ' + greeting); - * }, function(reason) { - * alert('Failed: ' + reason); - * }, function(update) { - * alert('Got notification: ' + update); - * }); - * ``` - * - * At first it might not be obvious why this extra complexity is worth the trouble. The payoff - * comes in the way of guarantees that promise and deferred APIs make, see - * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md. - * - * Additionally the promise api allows for composition that is very hard to do with the - * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach. - * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the - * section on serial or parallel joining of promises. - * - * ## The Deferred API - * - * A new instance of deferred is constructed by calling `$q.defer()`. - * - * The purpose of the deferred object is to expose the associated Promise instance as well as APIs - * that can be used for signaling the successful or unsuccessful completion, as well as the status - * of the task. - * - * **Methods** - * - * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection - * constructed via `$q.reject`, the promise will be rejected instead. - * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to - * resolving it with a rejection constructed via `$q.reject`. - * - `notify(value)` - provides updates on the status of the promise's execution. This may be called - * multiple times before the promise is either resolved or rejected. - * - * **Properties** - * - * - promise – `{Promise}` – promise object associated with this deferred. - * - * - * ## The Promise API - * - * A new promise instance is created when a deferred instance is created and can be retrieved by - * calling `deferred.promise`. - * - * The purpose of the promise object is to allow for interested parties to get access to the result - * of the deferred task when it completes. - * - * **Methods** - * - * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or - * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously - * as soon as the result is available. The callbacks are called with a single argument: the result - * or rejection reason. Additionally, the notify callback may be called zero or more times to - * provide a progress indication, before the promise is resolved or rejected. - * - * This method *returns a new promise* which is resolved or rejected via the return value of the - * `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved - * with the value which is resolved in that promise using - * [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)). - * It also notifies via the return value of the `notifyCallback` method. The promise cannot be - * resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback - * arguments are optional. - * - * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)` - * - * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise, - * but to do so without modifying the final value. This is useful to release resources or do some - * clean-up that needs to be done whether the promise was rejected or resolved. See the [full - * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for - * more information. - * - * ## Chaining promises - * - * Because calling the `then` method of a promise returns a new derived promise, it is easily - * possible to create a chain of promises: - * - * ```js - * promiseB = promiseA.then(function(result) { - * return result + 1; - * }); - * - * // promiseB will be resolved immediately after promiseA is resolved and its value - * // will be the result of promiseA incremented by 1 - * ``` - * - * It is possible to create chains of any length and since a promise can be resolved with another - * promise (which will defer its resolution further), it is possible to pause/defer resolution of - * the promises at any point in the chain. This makes it possible to implement powerful APIs like - * $http's response interceptors. - * - * - * ## Differences between Kris Kowal's Q and $q - * - * There are two main differences: - * - * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation - * mechanism in angular, which means faster propagation of resolution or rejection into your - * models and avoiding unnecessary browser repaints, which would result in flickering UI. - * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains - * all the important functionality needed for common async tasks. - * - * ## Testing - * - * ```js - * it('should simulate promise', inject(function($q, $rootScope) { - * var deferred = $q.defer(); - * var promise = deferred.promise; - * var resolvedValue; - * - * promise.then(function(value) { resolvedValue = value; }); - * expect(resolvedValue).toBeUndefined(); - * - * // Simulate resolving of promise - * deferred.resolve(123); - * // Note that the 'then' function does not get called synchronously. - * // This is because we want the promise API to always be async, whether or not - * // it got called synchronously or asynchronously. - * expect(resolvedValue).toBeUndefined(); - * - * // Propagate promise resolution to 'then' functions using $apply(). - * $rootScope.$apply(); - * expect(resolvedValue).toEqual(123); - * })); - * ``` - * - * @param {function(function, function)} resolver Function which is responsible for resolving or - * rejecting the newly created promise. The first parameter is a function which resolves the - * promise, the second parameter is a function which rejects the promise. - * - * @returns {Promise} The newly created promise. - */ -/** - * @ngdoc provider - * @name $qProvider - * @this - * - * @description - */ -function $QProvider() { - var errorOnUnhandledRejections = true;

Its goal is to assist in writing code in a way that (a) is secure by default, and - * (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier. - * - * ### Overview - * - * To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in - * HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically - * run security checks on them (sanitizations, whitelists, depending on context), or throw when it - * cannot guarantee the security of the result. That behavior depends strongly on contexts: HTML - * can be sanitized, but template URLs cannot, for instance. - * - * To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML: - * we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it - * before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and - * render the input as-is, you will need to mark it as trusted for that context before attempting - * to bind it. - * - * As of version 1.2, AngularJS ships with SCE enabled by default. - * - * ### In practice - * - * Here's an example of a binding in a privileged context: - * - * ``` - * - *

- * ``` - * - * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE - * disabled, this application allows the user to render arbitrary HTML into the DIV, which would - * be an XSS security bug. In a more realistic example, one may be rendering user comments, blog - * articles, etc. via bindings. (HTML is just one example of a context where rendering user - * controlled input creates security vulnerabilities.) - * - * For the case of HTML, you might use a library, either on the client side, or on the server side, - * to sanitize unsafe HTML before binding to the value and rendering it in the document. - * - * How would you ensure that every place that used these types of bindings was bound to a value that - * was sanitized by your library (or returned as safe for rendering by your server?) How can you - * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some - * properties/fields and forgot to update the binding to the sanitized value? - * - * To be secure by default, AngularJS makes sure bindings go through that sanitization, or - * any similar validation process, unless there's a good reason to trust the given value in this - * context. That trust is formalized with a function call. This means that as a developer, you - * can assume all untrusted bindings are safe. Then, to audit your code for binding security issues, - * you just need to ensure the values you mark as trusted indeed are safe - because they were - * received from your server, sanitized by your library, etc. You can organize your codebase to - * help with this - perhaps allowing only the files in a specific directory to do this. - * Ensuring that the internal API exposed by that code doesn't markup arbitrary values as safe then - * becomes a more manageable task. - * - * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs} - * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to - * build the trusted versions of your values. - * - * ### How does it work? - * - * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted - * $sce.getTrusted(context, value)} rather than to the value directly. Think of this function as - * a way to enforce the required security context in your data sink. Directives use {@link - * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs - * the {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. Also, - * when binding without directives, AngularJS will understand the context of your bindings - * automatically. - * - * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link - * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly - * simplified): - * - * ``` - * var ngBindHtmlDirective = ['$sce', function($sce) { - * return function(scope, element, attr) { - * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) { - * element.html(value || ''); - * }); - * }; - * }]; - * ``` - * - * ### Impact on loading templates - * - * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as - * `templateUrl`'s specified by {@link guide/directive directives}. - * - * By default, Angular only loads templates from the same domain and protocol as the application - * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl - * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or - * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist - * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value. - * - * *Please note*: - * The browser's - * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest) - * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/) - * policy apply in addition to this and may further restrict whether the template is successfully - * loaded. This means that without the right CORS policy, loading templates from a different domain - * won't work on all browsers. Also, loading templates from `file://` URL does not work on some - * browsers. - * - * ### This feels like too much overhead - * - * It's important to remember that SCE only applies to interpolation expressions. - * - * If your expressions are constant literals, they're automatically trusted and you don't need to - * call `$sce.trustAs` on them (e.g. - * `
`) just works. The `$sceDelegate` will - * also use the `$sanitize` service if it is available when binding untrusted values to - * `$sce.HTML` context. AngularJS provides an implementation in `angular-sanitize.js`, and if you - * wish to use it, you will also need to depend on the {@link ngSanitize `ngSanitize`} module in - * your application. - * - * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load - * templates in `ng-include` from your application's domain without having to even know about SCE. - * It blocks loading templates from other domains or loading templates over http from an https - * served document. You can change these by setting your own custom {@link - * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link - * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs. - * - * This significantly reduces the overhead. It is far easier to pay the small overhead and have an - * application that's secure and can be audited to verify that with much more ease than bolting - * security onto an application later. - * - * - * ### What trusted context types are supported? - * - * | Context | Notes | - * |---------------------|----------------| - * | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered, and the {@link ngSanitize.$sanitize $sanitize} service is available (implemented by the {@link ngSanitize ngSanitize} module) this will sanitize the value instead of throwing an error. | - * | `$sce.CSS` | For CSS that's safe to source into the application. Currently, no bindings require this context. Feel free to use it in your own directives. | - * | `$sce.URL` | For URLs that are safe to follow as links. Currently unused (`
Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does (it's not just the URL that matters, but also what is at the end of it), and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. | - * | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently, no bindings require this context. Feel free to use it in your own directives. | - * - * - * Be aware that `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them - * through {@link ng.$sce#getTrusted $sce.getTrusted}. There's no CSS-, URL-, or JS-context bindings - * in AngularJS currently, so their corresponding `$sce.trustAs` functions aren't useful yet. This - * might evolve. - * - * ### Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} - * - * Each element in these arrays must be one of the following: - * - * - **'self'** - * - The special **string**, `'self'`, can be used to match against all URLs of the **same - * domain** as the application document using the **same protocol**. - * - **String** (except the special value `'self'`) - * - The string is matched against the full *normalized / absolute URL* of the resource - * being tested (substring matches are not good enough.) - * - There are exactly **two wildcard sequences** - `*` and `**`. All other characters - * match themselves. - * - `*`: matches zero or more occurrences of any character other than one of the following 6 - * characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'. It's a useful wildcard for use - * in a whitelist. - * - `**`: matches zero or more occurrences of *any* character. As such, it's not - * appropriate for use in a scheme, domain, etc. as it would match too much. (e.g. - * http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might - * not have been the intention.) Its usage at the very end of the path is ok. (e.g. - * http://foo.example.com/templates/**). - * - **RegExp** (*see caveat below*) - * - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax - * (and all the inevitable escaping) makes them *harder to maintain*. It's easy to - * accidentally introduce a bug when one updates a complex expression (imho, all regexes should - * have good test coverage). For instance, the use of `.` in the regex is correct only in a - * small number of cases. A `.` character in the regex used when matching the scheme or a - * subdomain could be matched against a `:` or literal `.` that was likely not intended. It - * is highly recommended to use the string patterns and only fall back to regular expressions - * as a last resort. - * - The regular expression must be an instance of RegExp (i.e. not a string.) It is - * matched against the **entire** *normalized / absolute URL* of the resource being tested - * (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags - * present on the RegExp (such as multiline, global, ignoreCase) are ignored. - * - If you are generating your JavaScript from some other templating engine (not - * recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)), - * remember to escape your regular expression (and be aware that you might need more than - * one level of escaping depending on your templating engine and the way you interpolated - * the value.) Do make use of your platform's escaping mechanism as it might be good - * enough before coding your own. E.g. Ruby has - * [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape) - * and Python has [re.escape](http://docs.python.org/library/re.html#re.escape). - * Javascript lacks a similar built in function for escaping. Take a look at Google - * Closure library's [goog.string.regExpEscape(s)]( - * http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962). - * - * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example. - * - * ### Show me an example using SCE. - * - * - * - *

It must return an object that will be accepted by - * getTrusted() for a compatible contextEnum and return this value. - * - * - valueOf(value) - * For values that were not produced by trustAs(), return them as is. For values that were - * produced by trustAs(), return the corresponding input value to trustAs. Basically, if - * trustAs is wrapping the given values into some type, this operation unwraps it when given - * such a value. - * - * - getTrusted(contextEnum, value) - * This function should return the a value that is safe to use in the context specified by - * contextEnum or throw and exception otherwise. - * - * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be - * opaque or wrapped in some holder object. That happens to be an implementation detail. For - * instance, an implementation could maintain a registry of all trusted objects by context. In - * such a case, trustAs() would return the same object that was passed in. getTrusted() would - * return the same object passed in if it was found in the registry under a compatible context or - * throw an exception otherwise. An implementation might only wrap values some of the time based - * on some criteria. getTrusted() might return a value and not throw an exception for special - * constants or objects even if not wrapped. All such implementations fulfill this contract. - * - * - * A note on the inheritance model for SCE contexts - * ------------------------------------------------ - * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types. This - * is purely an implementation details. - * - * The contract is simply this: - * - * getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value) - * will also succeed. - * - * Inheritance happens to capture this in a natural way.

There is little value is mocking these out for this -// service. -var urlParsingNode = window.document.createElement('a'); -var originUrl = urlResolve(window.location.href); - - -/** - * - * Implementation Notes for non-IE browsers - * ---------------------------------------- - * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM, - * results both in the normalizing and parsing of the URL. Normalizing means that a relative - * URL will be resolved into an absolute URL in the context of the application document. - * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related - * properties are all populated to reflect the normalized URL. This approach has wide - * compatibility - Safari 1+, Mozilla 1+ etc. See - * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html - * - * Implementation Notes for IE - * --------------------------- - * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other - * browsers. However, the parsed components will not be set if the URL assigned did not specify - * them. (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.) We - * work around that by performing the parsing in a 2nd step by taking a previously normalized - * URL (e.g. by assigning to a.href) and assigning it a.href again. This correctly populates the - * properties such as protocol, hostname, port, etc. - * - * References: - * http://developer.mozilla.org/en-US/docs/Web/API/HTMLAnchorElement - * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html - * http://url.spec.whatwg.org/#urlutils - * https://github.com/angular/angular.js/pull/2902 - * http://james.padolsey.com/javascript/parsing-urls-with-the-dom/ - * - * @kind function - * @param {string} url The URL to be parsed. - * @description Normalizes and parses a URL. - * @returns {object} Returns the normalized URL as a dictionary. - * - * | member name | Description | - * |---------------|----------------| - * | href | A normalized version of the provided URL if it was not an absolute URL | - * | protocol | The protocol including the trailing colon | - * | host | The host and port (if the port is non-default) of the normalizedUrl | - * | search | The search params, minus the question mark | - * | hash | The hash string, minus the hash symbol - * | hostname | The hostname - * | port | The port, without ":" - * | pathname | The pathname, beginning with "/" - * - */ -function urlResolve(url) { - var href = url; - - // Support: IE 9-11 only - if (msie) { - // Normalize before parse.

- * **Note**: If the array contains objects that reference themselves, filtering is not possible. - *
- * @param {string|Object|function()} expression The predicate to be used for selecting items from - * `array`. - * - * Can be one of: - * - * - `string`: The string is used for matching against the contents of the `array`. All strings or - * objects with string properties in `array` that match this string will be returned. This also - * applies to nested object properties. - * The predicate can be negated by prefixing the string with `!`. - * - * - `Object`: A pattern object can be used to filter specific properties on objects contained - * by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items - * which have property `name` containing "M" and property `phone` containing "1". A special - * property name (`$` by default) can be used (e.g. as in `{$: "text"}`) to accept a match - * against any property of the object or its nested object properties. That's equivalent to the - * simple substring match with a `string` as described above. The special property name can be - * overwritten, using the `anyPropertyKey` parameter. - * The predicate can be negated by prefixing the string with `!`. - * For example `{name: "!M"}` predicate will return an array of items which have property `name` - * not containing "M". - * - * Note that a named property will match properties on the same level only, while the special - * `$` property will match properties on the same level or deeper.

Primitive values are converted to strings. Objects are not compared against - * primitives, unless they have a custom `toString` method (e.g. `Date` objects). - * - * - * Defaults to `false`. - * - * @param {string} [anyPropertyKey] The special property name that matches against any property. - * By default `$`. - * - * @example - - -

If none is specified, a default, built-in - * comparator is used (see below for details - in a nutshell, it compares numbers numerically and - * strings alphabetically). - * - * ### Under the hood - * - * Ordering the specified `collection` happens in two phases: - * - * 1. All items are passed through the predicate (or predicates), and the returned values are saved - * along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed - * through a predicate that extracts the value of the `label` property, would be transformed to: - * ``` - * { - * value: 'foo', - * type: 'string', - * index: ... - * } - * ``` - * 2. The comparator function is used to sort the items, based on the derived values, types and - * indices. - * - * If you use a custom comparator, it will be called with pairs of objects of the form - * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal - * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the - * second, or `1` otherwise. - * - * In order to ensure that the sorting will be deterministic across platforms, if none of the - * specified predicates can distinguish between two items, `orderBy` will automatically introduce a - * dummy predicate that returns the item's index as `value`. - * (If you are using a custom comparator, make sure it can handle this predicate as well.) - * - * If a custom comparator still can't distinguish between two items, then they will be sorted based - * on their index using the built-in comparator. - * - * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted - * value for an item, `orderBy` will try to convert that object to a primitive value, before passing - * it to the comparator. The following rules govern the conversion: - * - * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be - * used instead.
- * (If the object has a `valueOf()` method that returns another object, then the returned object - * will be used in subsequent steps.) - * 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that - * returns a primitive, its return value will be used instead.
- * (If the object has a `toString()` method that returns another object, then the returned object - * will be used in subsequent steps.) - * 3. No conversion; the object itself is used. - * - * ### The default comparator - * - * The default, built-in comparator should be sufficient for most usecases. In short, it compares - * numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to - * using their index in the original collection, and sorts values of different types by type. - * - * More specifically, it follows these steps to determine the relative order of items: - * - * 1. If the compared values are of different types, compare the types themselves alphabetically. - * 2. If both values are of type `string`, compare them alphabetically in a case- and - * locale-insensitive way. - * 3. If both values are objects, compare their indices instead. - * 4. Otherwise, return: - * - `0`, if the values are equal (by strict equality comparison, i.e. using `===`). - * - `-1`, if the 1st value is "less than" the 2nd value (compared using the `<` operator). - * - `1`, otherwise. - * - * **Note:** If you notice numbers not being sorted as expected, make sure they are actually being - * saved as numbers and not strings. - * **Note:** For the purpose of sorting, `null` values are treated as the string `'null'` (i.e. - * `type: 'string'`, `value: 'null'`). This may cause unexpected sort order relative to - * other values. - * - * @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort. - * @param {(Function|string|Array.)=} expression - A predicate (or list of - * predicates) to be used by the comparator to determine the order of elements. - * - * Can be one of: - * - * - `Function`: A getter function. This function will be called with each item as argument and - * the return value will be used for sorting. - * - `string`: An Angular expression. This expression will be evaluated against each item and the - * result will be used for sorting. For example, use `'label'` to sort by a property called - * `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label` - * property.
- * (The result of a constant expression is interpreted as a property name to be used for - * comparison. For example, use `'"special name"'` (note the extra pair of quotes) to sort by a - * property called `special name`.)
- * An expression can be optionally prefixed with `+` or `-` to control the sorting direction, - * ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided, - * (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons. - * - `Array`: An array of function and/or string predicates. If a predicate cannot determine the - * relative order of two items, the next predicate is used as a tie-breaker. - * - * **Note:** If the predicate is missing or empty then it defaults to `'+'`. - * - * @param {boolean=} reverse - If `true`, reverse the sorting order. - * @param {(Function)=} comparator - The comparator function used to determine the relative order of - * value pairs. If omitted, the built-in comparator will be used. - * - * @returns {Array} - The sorted array. - * - * - * @example - * ### Ordering a table with `ngRepeat` - * - * The example below demonstrates a simple {@link ngRepeat ngRepeat}, where the data is sorted by - * age in descending order (expression is set to `'-age'`). The `comparator` is not set, which means - * it defaults to the built-in comparator. - * - - -

This means that the outer form is valid when all of the child - * forms are valid as well. However, browsers do not allow nesting of `` elements, so - * Angular provides the {@link ng.directive:ngForm `ngForm`} directive, which behaves identically to - * `form` but can be nested. Nested forms can be useful, for example, if the validity of a sub-group - * of controls needs to be determined. - * - * ## CSS classes - * - `ng-valid` is set if the form is valid. - * - `ng-invalid` is set if the form is invalid. - * - `ng-pending` is set if the form is pending. - * - `ng-pristine` is set if the form is pristine. - * - `ng-dirty` is set if the form is dirty. - * - `ng-submitted` is set if the form was submitted. - * - * Keep in mind that ngAnimate can detect each of these classes when added and removed. - * - * - * ## Submitting a form and preventing the default action - * - * Since the role of forms in client-side Angular applications is different than in classical - * roundtrip apps, it is desirable for the browser not to translate the form submission into a full - * page reload that sends the data to the server. Instead some javascript logic should be triggered - * to handle the form submission in an application-specific way. - * - * For this reason, Angular prevents the default action (form submission to the server) unless the - * `` element has an `action` attribute specified. - * - * You can use one of the following two ways to specify what javascript method should be called when - * a form is submitted: - * - * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element - * - {@link ng.directive:ngClick ngClick} directive on the first - * button or input field of type submit (input[type=submit]) - * - * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit} - * or {@link ng.directive:ngClick ngClick} directives. - * This is because of the following form submission rules in the HTML specification: - * - * - If a form has only one input field then hitting enter in this field triggers form submit - * (`ngSubmit`) - * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter - * doesn't trigger submit - * - if a form has one or more input fields and one or more buttons or input[type=submit] then - * hitting enter in any of the input fields will trigger the click handler on the *first* button or - * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`) - * - * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is - * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit` - * to have access to the updated model. - * - * @animations - * Animations in ngForm are triggered when any of the associated CSS classes are added and removed. - * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any - * other validations that are performed within the form. Animations in ngForm are similar to how - * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well - * as JS animations. - * - * The following example shows a simple way to utilize CSS transitions to style a form element - * that has been rendered as invalid after it has been validated: - * - * 
- * //be sure to include ngAnimate as a module to hook into more
- * //advanced animations
- * .my-form {
- *   transition:0.5s linear all;
- *   background: white;
- * }
- * .my-form.ng-invalid {
- *   background: red;
- *   color:white;
- * }
- *
- * - * @example - - - - - - userType: - Required!
- userType = {{userType}}
- myForm.input.$valid = {{myForm.input.$valid}}
- myForm.input.$error = {{myForm.input.$error}}
- myForm.$valid = {{myForm.$valid}}
- myForm.$error.required = {{!!myForm.$error.required}}

Model binding, - * validation and number parsing are nevertheless supported. - * - * Browsers that support range (latest Chrome, Safari, Firefox, Edge) treat `input[range]` - * in a way that never allows the input to hold an invalid value. That means: - * - any non-numerical value is set to `(max + min) / 2`. - * - any numerical value that is less than the current min val, or greater than the current max val - * is set to the min / max val respectively. - * - additionally, the current `step` is respected, so the nearest value that satisfies a step - * is used. - * - * See the [HTML Spec on input[type=range]](https://www.w3.org/TR/html5/forms.html#range-state-(type=range)) - * for more info. - * - * This has the following consequences for Angular: - * - * Since the element value should always reflect the current model value, a range input - * will set the bound ngModel expression to the value that the browser has set for the - * input element. For example, in the following input ``, - * if the application sets `model.value = null`, the browser will set the input to `'50'`. - * Angular will then set the model to `50`, to prevent input and model value being out of sync. - * - * That means the model for range will immediately be set to `50` after `ngModel` has been - * initialized. It also means a range input can never have the required error. - * - * This does not only affect changes to the model value, but also to the values of the `min`, - * `max`, and `step` attributes. When these change in a way that will cause the browser to modify - * the input value, Angular will also update the model value. - * - * Automatic value adjustment also means that a range input element can never have the `required`, - * `min`, or `max` errors. - * - * However, `step` is currently only fully implemented by Firefox. Other browsers have problems - * when the step value changes dynamically - they do not adjust the element value correctly, but - * instead may set the `stepMismatch` error. If that's the case, the Angular will set the `step` - * error on the input, and set the model to `undefined`. - * - * Note that `input[range]` is not compatible with`ngMax`, `ngMin`, and `ngStep`, because they do - * not set the `min` and `max` attributes, which means that the browser won't automatically adjust - * the input value based on their values, and will always assume min = 0, max = 100, and step = 1. - * - * @param {string} ngModel Assignable angular expression to data-bind to. - * @param {string=} name Property name of the form under which the control is published. - * @param {string=} min Sets the `min` validation to ensure that the value entered is greater - * than `min`.

This is important to know when - * binding inputs to models that are objects (e.g. `Date`) or collections (e.g. arrays). If only properties of the - * object or collection change, `ngModel` will not be notified and so the input will not be re-rendered. - * - * The model must be assigned an entirely new object or collection before a re-rendering will occur. - * - * Some directives have options that will cause them to use a custom `$watchCollection` on the model expression - * - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or - * if the select is given the `multiple` attribute. - * - * The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the - * first level of the object (or only changing the properties of an item in the collection if it's an array) will still - * not trigger a re-rendering of the model. - * - * ## CSS classes - * The following CSS classes are added and removed on the associated input/select/textarea element - * depending on the validity of the model. - * - * - `ng-valid`: the model is valid - * - `ng-invalid`: the model is invalid - * - `ng-valid-[key]`: for each valid key added by `$setValidity` - * - `ng-invalid-[key]`: for each invalid key added by `$setValidity` - * - `ng-pristine`: the control hasn't been interacted with yet - * - `ng-dirty`: the control has been interacted with - * - `ng-touched`: the control has been blurred - * - `ng-untouched`: the control hasn't been blurred - * - `ng-pending`: any `$asyncValidators` are unfulfilled - * - `ng-empty`: the view does not contain a value or the value is deemed "empty", as defined - * by the {@link ngModel.NgModelController#$isEmpty} method - * - `ng-not-empty`: the view contains a non-empty value - * - * Keep in mind that ngAnimate can detect each of these classes when added and removed. - * - * @animations - * Animations within models are triggered when any of the associated CSS classes are added and removed - * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`, - * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself. - * The animations that are triggered within ngModel are similar to how they work in ngClass and - * animations can be hooked into using CSS transitions, keyframes as well as JS animations. - * - * The following example shows a simple way to utilize CSS transitions to style an input element - * that has been rendered as invalid after it has been validated: - * - * 
- * //be sure to include ngAnimate as a module to hook into more
- * //advanced animations
- * .my-input {
- *   transition:0.5s linear all;
- *   background: white;
- * }
- * .my-input.ng-invalid {
- *   background: red;
- *   color:white;
- * }
- *
- * - * @example - * ### Basic Usage - * - - - -

- Update input to see transitions when valid/invalid. - Integer is a valid value. -

A getter/setter is a - * function that returns a representation of the model when called with zero arguments, and sets - * the internal state of a model when called with an argument. It's sometimes useful to use this - * for models that have an internal representation that's different from what the model exposes - * to the view. - * - *
- * **Best Practice:** It's best to keep getters fast because Angular is likely to call them more - * frequently than other parts of your code. - *
- * - * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that - * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to - * a `
`, which will enable this behavior for all ``s within it. See - * {@link ng.directive:ngModelOptions `ngModelOptions`} for more. - * - * The following example shows how to use `ngModel` with a getter/setter: - * - * @example - * - -

You can specify an `ngModelOptions` directive on any element. All {@link ngModel} - * directives will use the options of their nearest `ngModelOptions` ancestor. - * - * The `ngModelOptions` settings are found by evaluating the value of the attribute directive as - * an Angular expression. This expression should evaluate to an object, whose properties contain - * the settings. For example: `
- *
- * - *
- *
- * ``` - * - * the `input` element will have the following settings - * - * ```js - * { allowInvalid: true, updateOn: 'default', debounce: 0 } - * ``` - * - * Notice that the `debounce` setting was not inherited and used the default value instead. - * - * You can specify that all undefined settings are automatically inherited from an ancestor by - * including a property with key of `"*"` and value of `"$inherit"`. - * - * For example given the following fragment of HTML - * - * - * ```html - *
- *
- * - *
- *
- * ``` - * - * the `input` element will have the following settings - * - * ```js - * { allowInvalid: true, updateOn: 'default', debounce: 200 } - * ``` - * - * Notice that the `debounce` setting now inherits the value from the outer `
` element. - * - * If you are creating a reusable component then you should be careful when using `"*": "$inherit"` - * since you may inadvertently inherit a setting in the future that changes the behavior of your component. - * - * - * ## Triggering and debouncing model updates - * - * The `updateOn` and `debounce` properties allow you to specify a custom list of events that will - * trigger a model update and/or a debouncing delay so that the actual update only takes place when - * a timer expires; this timer will be reset after another change takes place. - * - * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might - * be different from the value in the actual model. This means that if you update the model you - * should also invoke {@link ngModel.NgModelController#$rollbackViewValue} on the relevant input field in - * order to make sure it is synchronized with the model and that any debounced action is canceled. - * - * The easiest way to reference the control's {@link ngModel.NgModelController#$rollbackViewValue} - * method is by making sure the input is placed inside a form that has a `name` attribute. This is - * important because `form` controllers are published to the related scope under the name in their - * `name` attribute. - * - * Any pending changes will take place immediately when an enclosing form is submitted via the - * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit` - * to have access to the updated model. - * - * The following example shows how to override immediate updates. Changes on the inputs within the - * form will update the model only when the control loses focus (blur event). If `escape` key is - * pressed while the input field is focused, the value is reset to the value in the current model. - * - * - * - *

By setting the `allowInvalid` property to true, - * the model will still be updated even if the value is invalid. - * - * - * ## Connecting to the scope - * - * By setting the `getterSetter` property to true you are telling ngModel that the `ngModel` expression - * on the scope refers to a "getter/setter" function rather than the value itself. - * - * The following example shows how to bind to getter/setters: - * - * - * - *

A - * value of 0 triggers an immediate update. If an object is supplied instead, you can specify a - * custom value for each event. For example: - * ``` - * ng-model-options="{ - * updateOn: 'default blur', - * debounce: { 'default': 500, 'blur': 0 } - * }" - * ``` - * - `allowInvalid`: boolean value which indicates that the model can be set with values that did - * not validate correctly instead of the default behavior of setting the model to undefined. - * - `getterSetter`: boolean value which determines whether or not to treat functions bound to - * `ngModel` as getters/setters. - * - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for - * ``, ``, ... .
