如何使用 Puppeteer 在选项卡之间切换? [英] How to switch between tabs with Puppeteer?

问题描述

这是我的用例:

我有一个链接，点击它会打开一个新标签并加载内容.

I have a link which on clicking opens a new tab and loads the content.

我在找什么:

有没有办法在新标签打开时切换页面的引用或为新标签创建引用?

Is there a way to switch the reference of the page while new tab opens or create a reference for the new tab?

推荐答案

要获取点击链接后打开的页面，可以在 popup 事件.当页面打开新选项卡或窗口时发出.

To get the page that was opened after a link is clicked, you can listen on the popup event. It is emitted when the page opens a new tab or window.

代码示例(来自上面链接的文档)

Code sample (from the docs linked above)

const [newPage] = await Promise.all([
    new Promise(resolve => page.once('popup', resolve)),
    page.click('a[target=_blank]'),
]);

这将在等待当前页面打开一个窗口时点击链接.newPage 将是打开的页面.

This will click on the link while waiting for a window to be opened by the current page. newPage will be the opened page.

替代方法:要获取所有打开页面的列表，您可以使用 browser.pages:

Alternative approach: To get a list of all open pages, you can use browser.pages:

const pages = await browser.pages();

pages 将是一个包含所有打开页面的数组.

pages will be an array with all open pages.
