Fixes https://github.com/SerenityOS/serenity/issues/2649
Loading a page with iframes could lead to a scenario, where the iframe
document finished layout prior to the main frame beeing laid out
initially. This caused a crash/assertion of the browser.
This should enable to destinguish between IFrame, Reload and Navigation
motivated loads in order to call the appropriate hooks.
This change is motivated as loading the IFrame test page causes the
IFrame url to be added to the history and shows up as the current
browser location bar.
"width: 500" is not a valid CSS property in standards mode and should
be ignored.
To plumb the quirks-mode flag into CSS parsing, this patch adds a new
CSS::ParsingContext object that must be passed to the CSS parser.
Currently it only allows you to check the quirks-mode flag. In the
future it will be a good place to put additional information needed
for things like relative URL resolution, etc.
This narrows <div class=parser> on ACID2 to the correct width. :^)
This patch adds a Web::Timer object that represents a single timer
registration made with window.setTimeout() or window.setInterval().
All live timers are owned by the DOM Window object.
The timers can be stopped via clearTimeout() or clearInterval().
Note that those API's are actually interchangeable, but we have to
support both.
This patch implements most of the HTML fragment parsing algorithm and
ports Element::set_inner_html() to it. This was the last remaining user
of the old HTML parser. :^)
To make this possible, I also had to give each LayoutNode a Document&
so it can resolve document-specific colors correctly. There's probably
ways to avoid having this extra member by resolving colors later, but
this works for now.
Instead of taking the JS::Heap&. This allows us to get rid of some
calls to JS::Interpreter::global_object(). We're getting closer and
closer to multiple global objects. :^)
Now that we're using the new HTML parser, we don't have to do the weird
"run the script when inserted into the document, uhh, or when the text
content of the script element changes" dance.
Instead, we just follow the spec, and scripts run the way they should.
We now use the ImageDecoder service in LibWeb for everything except
GIF images (we'll have to deal with them later, ofc.)
This has a little bit of overhead but we should be able to optimize
it until it becomes negligible.
We're still missing optional argument support, so this implementation
doesn't support fill(), only fill(fill_rule).
Still it's really nice to get rid of so much hand-written wrapper code.
We still have to hand-write a function to turn an Event& into a wrapper
but this is still a hue improvement. Eventually we'll find a way to
auto-generate that function as well.
This is a very barebones implementation of appendChild() that doesn't
take any of the idiosyncratic DOM behaviors into account yet.
Also teach the wrapper generator how to turn an Interpreter argument
into a Node&.
This patch introduces a hackish but functional IDL parser and uses it
to generate the JS bindings for Node and Document.
We'll see how far this simple parser takes us. The important thing
right now is generating code, not being a perfect IDL parser. :^)
The more generic virtual variant is renamed to node_name() and now only
Element has tag_name(). This removes a huge amount of String ctor/dtor
churn in selector matching.
This patch implements a simple <object> element with fallback content.
If the URL from the data attribute fails to load (including 404),
we render the DOM tree inside the <object> as fallback content.
This works by generating a different layout tree for the <object>
depending on the state and success of the data load. Since we cannot
currently do incremental layout tree updates, we have to force a
complete layout tree rebuild when the resource load finishes/fails.
Since more DOM nodes are going to want to load images (<object>, ...)
this patch splits out the image loading logic into an ImageLoader class
and then HTMLImageElement simply has an ImageLoader.
LayoutImage is then given a const ImageLoader& at construction and can
then provide layout and rendering for many kinds of DOM nodes.
