Question

点击播放Youtube视频

8

我正在使用Youtube API，并且有几个Div作为缩略图。当单击一个缩略图（div）时，应播放相应的Youtube视频。我正在使用iframe元素进行视频播放，网页仅由HTML、CSS和JavaScript组成。如果我不使用按钮（具有onclick的缩略图/ div），而是使用带有Youtube API JavaScript代码的空白页面，它将起作用。但是，当我尝试将所有内容包装在函数调用中（从div的onclick），什么都不会发生，但是我会收到以下错误消息。

"Refused to execute script from 'https://www.youtube.com/embed/HVldRjNb4BE' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled."

这是我的代码：

HTML：

<div id="player"></div>

JavaScript:

// 2. This code loads the IFrame Player API code asynchronously.
  var tag = document.createElement('script');

  tag.src = "https://www.youtube.com/iframe_api";
  var firstScriptTag = document.getElementsByTagName('script')[0];
  firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

  // 3. This function creates an <iframe> (and YouTube player)
  //    after the API code downloads.
  var player;
  function onYouTubeIframeAPIReady() {
    player = new YT.Player('player', {
      height: '390',
      width: '640',
      videoId: 'M7lc1UVf-VE',
      events: {
        'onReady': onPlayerReady,
        'onStateChange': onPlayerStateChange
      }
    });
  }

  // 4. The API will call this function when the video player is ready.
  function onPlayerReady(event) {
    event.target.playVideo();
  }

  // 5. The API calls this function when the player's state changes.
  //    The function indicates that when playing a video (state=1),
  //    the player should play for six seconds and then stop.
  var done = false;
  function onPlayerStateChange(event) {
    if (event.data == YT.PlayerState.PLAYING && !done) {
      //setTimeout(stopVideo, 6000);
      done = true;
    }
  }
  function stopVideo() {
    player.stopVideo();
  }

这段代码是从https://developers.google.com/youtube/iframe_api_reference复制的。

如果这是文档中唯一的内容，当页面加载时会有一个播放器，视频也已准备好播放。因此，为了澄清我的问题，我该如何做才能让用户点击其中一个按钮（div）时，Youtube播放器显示并播放视频呢？

我知道这是一个旧的帖子，但它是谷歌搜索结果中排名靠前的。在JavaScript中播放YouTube视频的更简单的方法是将YouTube Iframe对象的src属性更改为包含?autoplay=1属性。 JavaScript：

document.getElementById('my_youtube').src = 'https://www.youtube.com/embed/VIDEO_ID?autoplay=1'

HTML：

<iframe id="my_youtube" width="560" height="315" src="https://www.youtube.com/embed/VIDEO_ID" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen></iframe>

上面的 JavaScript 代码可以添加到 onclick 处理程序中。

你好，我认为这可以帮助你：

<!doctype html>
<html>
    <head>
        <meta charset="utf-8">
        <title>Play Youtube Video On Click</title>
    </head>
    <body>
        <button onclick="myFunction();return false;">Click me</button>
        <div id="video"></div>

        <script>
            function myFunction() {
                document.getElementById("video").innerHTML = "<div id='player'></div>";

                // 2. This code loads the IFrame Player API code asynchronously.
                var tag = document.createElement('script');

                tag.src = "https://www.youtube.com/iframe_api";
                var firstScriptTag = document.getElementsByTagName('script')[0];
                firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
            }

            // 3. This function creates an <iframe> (and YouTube player)

            // 4. The API will call this function when the video player is ready.
            function onPlayerReady(event) {

                    done = true;
                }
            }
            function stopVideo() {
                player.stopVideo();
            }
