如何处理 poppeteer 中的弹出窗口

Question

how to handle the popup and access the popup to do some operations on it.

const puppeteer = require('puppeteer');

async function run() {
    const browser = await puppeteer.launch();
    const page = await browser.newPage();
    await page.goto('https://example.com');
    await page.click(Launchpopup);
}

Answer 1

Since version 0.13.0, you can use the following code:

... code to open popup...
const pages = await browser.pages(); // get all open pages by the browser
const popup = pages[pages.length - 1]; // the popup should be the last page opened

Answer 2

This code is Typescript, but you get the idea:

async function waitForPopupMatching(
  browser: Puppeteer.Browser,
  regex: RegExp,
  openAction: () => Promise<void>,
  timeout: number = 30000,
): Promise<Puppeteer.Page> {
  const promise = new Bluebird<Puppeteer.Target>(resolve => {
    const listener = async (target: Puppeteer.Target) => {
      if (target.type() === 'page' && regex.test(target.url())) {
        browser.removeListener('targetcreated', listener);
        resolve(target);
      }
    };
    browser.addListener('targetcreated', listener);
  }).timeout(timeout);

  await openAction(); // Typically a mouse click

  const tgt = await promise;
  return await tgt.page();
}

Puppeteer popup event

Starting with puppeteer version 1.12, a special 'popup' event has been added to the page, which allows you to catch new tabs and popups. We use it by rewriting the first example:

const puppeteer = require('puppeteer');         // puppeteer

const browser = await puppeteer.launch();       // run browser
const page = await browser.newPage();           // open new tab
await page.goto('https://example.com');            // go to site.com       

await page.waitForSelector('#goto');            // wait object load
const link = await page.$('#goto');             // declare object

const newPagePromise = new Promise(x => page.once('popup', x));

await link.click();                        // click, a new tab  opens
const newPage = await newPagePromise; 
await newPage.close();             // close it, for example
await browser.close();                          // close browser

You should check out the documentation for v0.12.0-alpha, it describes how to interact with dialogs.

const puppeteer = require('puppeteer');

puppeteer.launch().then(async browser => {
  const page = await browser.newPage();
  await page.goto('https://example.com');
  page.on('dialog', async dialog => {
    console.log(dialog.message());
    await dialog.dismiss();
    await browser.close();
  });
  page.evaluate(() => alert('1'));
});
