大佬教程收集整理的这篇文章主要介绍了如何从 chrome 获取 DOM.shadowRootPushed 事件？，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

如何解决如何从 chrome 获取 DOm.shadowRootPushed 事件？？

开发过程中遇到如何从 chrome 获取 DOm.shadowRootPushed 事件？的问题如何解决？下面主要结合日常开发的经验，给出你关于如何从 chrome 获取 DOm.shadowRootPushed 事件？的解决方法建议，希望对你解决如何从 chrome 获取 DOm.shadowRootPushed 事件？有所启发或帮助；

我一直在尝试使用 DOm.shadowRootPushed 中的 CDPSession 获取 puppeteer 事件。这是加载包含 shadowRoot 的页面：

<HTML>
<head>
  <title>
    Page with Shadow Root
  </title>
</head>
<body>
  <header ID="host">
    <h1>Hello DOM</h1>
  </header>
</body>
<script>
  var attachShadow = HTMLElement.prototype.attachShadow

  HTMLElement.prototype.attachShadow = function ( option )
  {
    var sh = attachShadow.call( this,option )
    console.info( '%s shadow attached to %s',option.mode,this )
    //add a MutationObserver here
    return sh
  }
  setTimeout(function() {
    const host = document.getElementByID('host');
    const shadowRoot = host.attachShadow({mode: 'open'});
    shadowRoot.INNERHTML = '<h1>Hello Shadow DOM</h1>';
  },3300);
</script>
</HTML>

而且，我使用这个脚本来获取事件：

const puppeteer = require('puppeteer');

(async() => {
  // Use Puppeteer to launch a browser and open a page.
  const browser = await puppeteer.launch({
      headless: false
      // userDataDir: "/home/w/.config/chromium/"
    });
  const page = await browser.newPage();

  // Create a raw DevTools protocol session to talk to the page.
  // Use CDP to set the animation playBACk rate.
  const session = await page.target().createCDPSession();
  await session.send('Animation.enable');
  await session.send('DOm.enable');
  
  session.on('Animation.animationCreated',() => {
    console.log('Animation created!');
  });
  session.on('DOm.shadowRootPushed',() => {
    console.log('DOm.shadowRootPushed');
  });
  session.on('DOm.shadowRootPopped',() => {
    console.log('DOm.shadowRootPopped');
  });

  await session.send('Animation.setPlayBACkRate',{
    playBACkRate: 2,});


  // check it out! Fast animations on the "loading..." screen!
  // await page.goto('https://pptr.dev');
  await page.goto('http://localhost:8000');
  await wait(1115000)
  console.log("Done")
})();

async function wait(ms) {
  return new Promise(resolve => setTimeout(resolve,ms));
}

不过我得到了 Animation.animationCreated。 CDP 网站说 DOm.shadowRootPushed 是一个实验性事件。是否需要在启动选项中传递标志？依赖项：

  "dependencIEs": {
    "puppeteer": "8.0.0","ws": "7.2.3"
  },

Chrome Version：版本 90.0.4427.0（开发者版本）（64 位）

更新：

根据评论，我添加了以下标志：

args: [
        '--enable-blink-test-features','--enable-experimental-web-platform-features','--fake-variations-chAnnel=canary'
      ]

并为 dev 应用 beta、canary、stable、--fake-variations-chAnnel。未捕获通知。
