如何使用 javascript 从优酷播放视频？

我试图这样做但没有工作，我该怎么做？

<iframe id="test" src="https://player.youku.com/embed/XMjUzMzY2ODQ4OA==" frameborder="0" webkitallowfullscreen="" mozallowfullscreen="" allowfullscreen="" style="position: absolute; top: 0; left: 0; width: 50%; height: 50%;"></iframe>


<div style=" position: fixed; top: 56%; " onclick="play_fn()">Play</div>

<script>
function play_fn(){
    var test = document.getElementById('test');
    test.play();
}
</script>

play()是在<video>和<audio>元素上找到的方法。An<iframe>只是在页面中嵌入 URL 的一种方式。它不提供用于播放媒体的 API。

除非优酷提供您可以访问的 API（我无法通过快速搜索找到一个），否则无法从您的页面触发播放。

浏览器施加的标准跨源安全限制阻止您使用 JavaScript 操作嵌入页面。

检查我的解决方案。您可以根据自己的情况找出样式，我span在视频上方使用 as 叠加层，当您单击它时，它会消失并播放视频。

const videoSection = document.querySelector('.video');
    if(videoSection) {
    	const playBtn = document.querySelector('.play-btn');
    	playBtn.addEventListener('click', playVideo);
    }

    function playVideo() {
    	const iframeHolder = document.querySelector('.iframe-holder');
    	const iframeEl = document.querySelector('.iframe-holder iframe');
    	const playStr = '?autoplay=true';
    	let baseUrl = iframeEl.getAttribute('src');
    	
    	iframeHolder.classList.add('play');
    	iframeEl.setAttribute('src', `${baseUrl}${playStr}`);
    	iframeEl.setAttribute('allow', 'autoplay');
    }

    }

参考这段代码

    <!DOCTYPE html>
<html>
<head>
  <meta http-equiv="content-type" content="text/html; charset=UTF-8">
  <meta name="robots" content="noindex, nofollow">
  <meta name="googlebot" content="noindex, nofollow">
  <script type="text/javascript" src="/js/lib/dummy.js"></script>
  <link rel="stylesheet" type="text/css" href="/css/result-light.css">




  <style type="text/css">
      #overlay {
  position: absolute; 
  top: 100px; 
  color: #FFF; 
  text-align: center;
  font-size: 20px;
  background-color: rgba(221, 221, 221, 0.3);
  width: 640px;
  padding: 10px 0;
  z-index: 2147483647;
}

#v {
  z-index: 1;
}
  </style>
