# Multi-page scenarios
|
|
|
|
Playwright can automate scenarios that span multiple browser contexts or multiple
|
|
tabs in a browser window.

## Multiple contexts
|
|
|
|
[Browser contexts](core-concepts.md#browser-contexts) are isolated environments
|
|
on a single browser instance. Playwright can create multiple browser contexts
|
|
within a single scenario. This is useful when you want to test for
|
|
multi-user functionality, like chat.
|
|
|
|
```js
|
|
const { chromium } = require('playwright');
|
|
|
|
// Create a Chromium browser instance
|
|
const browser = await chromium.launch();
|
|
|
|
// Create two isolated browser contexts
|
|
const userContext = await browser.newContext();
|
|
const adminContext = await browser.newContext();
|
|
|
|
// Load user and admin cookies
|
|
await userContext.addCookies(userCookies);
|
|
await adminContext.addCookies(adminCookies);
|
|
```
|
|
|
|
#### API reference
|
|
|
|
- [class `BrowserContext`](./api.md#class-browsercontext)
|
|
- [`browser.newContext([options])`](./api.md#browsernewcontextoptions)
|
|
- [`browserContext.addCookies(cookies)`](api.md#browsercontextaddcookiescookies)
|
|
|
|
## Multiple pages
|
|
|
|
Each browser context can host multiple pages (tabs).
|
|
|
|
* Each page behaves like a focused, active page. Bringing the page to front
|
|
is not required.
|
|
* Pages inside a context respect context-level emulation, like viewport sizes,
|
|
custom network routes or browser locale.
|
|
|
|
```js
|
|
// Create two pages
|
|
const pageOne = await context.newPage();
|
|
const pageTwo = await context.newPage();
|
|
|
|
// Get pages of a brower context
|
|
const allPages = context.pages();
|
|
```
|
|
|
|
#### API reference
|
|
|
|
- [class `Page`](./api.md#class-page)
|
|
- [`browserContext.newPage()`](./api.md#browsercontextnewpage)
|
|
- [`browserContext.pages()`](./api.md#browsercontextpages)
|
|
|
|
## Handling new pages
|
|
|
|
The `page` event on browser contexts can be used to get new pages that are
|
|
created in the context. This can be used to handle new pages opened by
|
|
`target="_blank"` links.
|
|
|
|
```js
|
|
// Get page after a specific action (e.g. clicking a link)
|
|
const [newPage] = await Promise.all([
|
|
context.waitForEvent('page'),
|
|
page.evaluate(() => window.open('https://google.com', '_blank'))
|
|
])
|
|
await newPage.waitForLoadState();
|
|
console.log(await newPage.title());
|
|
|
|
// Get all new pages (including popups) in the context
|
|
context.on('page', async page => {
|
|
await page.waitForLoadState();
|
|
await page.title();
|
|
})
|
|
```
|
|
|
|
#### API reference
|
|
|
|
- [event: 'page'](./api.md#event-page)
|
|
|
|
## Handling popups
|
|
|
|
If the page opens a pop-up, you can get a reference to it by listening to the
|
|
`popup` event on the page.
|
|
|
|
This event is emitted in addition to the `browserContext.on('page')` event, but
|
|
only for popups relevant to this page.
|
|
|
|
```js
|
|
// Get popup after a specific action (e.g., click)
|
|
const [popup] = await Promise.all([
|
|
page.waitForEvent('popup'),
|
|
page.click('#open')
|
|
]);
|
|
await popup.waitForLoadState();
|
|
await popup.title();
|
|
|
|
// Get all popups when they open
|
|
page.on('popup', async popup => {
|
|
await popup.waitForLoadState();
|
|
await popup.title();
|
|
})
|
|
```
|
|
|
|
#### API reference
|
|
|
|
- [event: 'popup'](./api.md#event-popup)
