每个 BrowserContext 可以有多个页面。页面 指的是浏览器上下文中的单个选项卡或弹出窗口。它应用于导航到 URL 并与页面内容交互。

Each BrowserContext can have multiple pages. A Page refers to a single tab or a popup window within a browser context. It should be used to navigate to URLs and interact with the page content.

// Create a page.
const page = await context.newPage();

// Navigate explicitly, similar to entering a URL in the browser.
await page.goto('');
// Fill an input.
await page.locator('#search').fill('query');

// Navigate implicitly by clicking a link.
await page.locator('#submit').click();
// Expect a new url.


Multiple pages


Each browser context can host multiple pages (tabs).

  • 每个页面的行为就像一个集中的活动页面。不需要将页面置于前面。

    Each page behaves like a focused, active page. Bringing the page to front is not required.

  • 上下文内的页面遵循上下文级模拟,例如视口大小、自定义网络路由或浏览器区域设置。

    Pages inside a context respect context-level emulation, like viewport sizes, custom network routes or browser locale.

// Create two pages
const pageOne = await context.newPage();
const pageTwo = await context.newPage();

// Get pages of a browser context
const allPages = context.pages();


Handling new pages

浏览器上下文中的 page 事件可用于获取在上下文中创建的新页面。这可用于处理 target="_blank" 链接打开的新页面。

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.

// Start waiting for new page before clicking. Note no await.
const pagePromise = context.waitForEvent('page');
await page.getByText('open new tab').click();
const newPage = await pagePromise;
await newPage.waitForLoadState();
console.log(await newPage.title());


If the action that triggers the new page is unknown, the following pattern can be used.

// Get all new pages (including popups) in the context
context.on('page', async page => {
await page.waitForLoadState();
console.log(await page.title());


Handling popups

如果页面打开了一个弹出窗口(例如通过 target="_blank" 链接打开的页面),你可以通过监听页面上的 popup 事件来获取对其的引用。

If the page opens a pop-up (e.g. pages opened by target="_blank" links), you can get a reference to it by listening to the popup event on the page.

除了 browserContext.on('page') 事件之外,还会触发此事件,但仅针对与此页面相关的弹出窗口。

This event is emitted in addition to the browserContext.on('page') event, but only for popups relevant to this page.

// Start waiting for popup before clicking. Note no await.
const popupPromise = page.waitForEvent('popup');
await page.getByText('open the popup').click();
const popup = await popupPromise;
// Wait for the popup to load.
await popup.waitForLoadState();
console.log(await popup.title());


If the action that triggers the popup is unknown, the following pattern can be used.

// Get all popups when they open
page.on('popup', async popup => {
await popup.waitForLoadState();
console.log(await popup.title());
