如何处理弹出窗口并访问弹出窗口对其进行一些操作.

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

从0.13.0版本开始，可以使用以下代码：

... 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

所以我所做的是我在他们的主页上登录到 facebook，然后导航到我想去的页面，我点击它使用 facebook 按钮登录。然后下面的代码将在弹出窗口发生时单击带有 facebook 按钮的登录。

        await page.click('[service_name="facebook"]')
        const newPagePromise = new Promise(x => browser.once('targetcreated', target => x(target.page()))); 
        const popup = await newPagePromise;
        await popup.waitForSelector('[name="__CONFIRM__"]')
        const confirm = await popup.$('[name="__CONFIRM__"]')
        await popup.click('[name="__CONFIRM__"]')
        await page.waitFor(2000);
        await page.goto('your login page'); $

这段代码是 Typescript，但你明白了：

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();
}

您应该查看 v0.12.0-alpha 的文档，它描述了如何与对话框交互。

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'));
});
