Switching between tabs in puppeteer

问题

How to switch between current opened tab to the parent tab using puppeteer?

I have a home page and when i click on the link in home page it opens a new tab. After that page is loading i need to switch to home page.

You can use the browser.pages() method, it returns a promise which resolves to an array of all open pages.

const firstTab = (await browser.pages())[0];
const secondTab = (await browser.pages())[1];

Also, you can use event popup, emitted when the page opens a new tab or window.

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

const [popup] = await Promise.all([
 new Promise(resolve => page.once('popup', resolve)),
 page.evaluate(() => window.open('https://example.com')),
]);
