点击播放Youtube视频

我正在使用Youtube API，并有几个Div作为缩略图。单击一个缩略图（div）时，应播放相应的Youtube视频。我正在为视频使用iframe元素，而网页仅由HTML，CSS和JavaScript组成。如果我不使用按钮（缩略图/ div与onclick），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时（来自div的onclick）没有任何反应，但是我得到了这个错误。

“拒绝执行来自'https://www.youtube.com/embed/HVldRjNb4BE'的脚本，因为其MIME类型（'text / html'）不可执行，并且启用了严格的MIME类型检查。”

这是我的代码：

HTML：

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

的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();
  }

此代码仅从https://developers.google.com/youtube/iframe_api_reference复制而来。

当这是我在文档中的全部内容时，当页面加载时，播放器就在那里，并且视频已准备好播放。所以为了澄清我的问题，我怎样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？

您好我认为这会对您有所帮助：

<!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)
            //    after the API code downloads.
            var player;
            function onYouTubeIframeAPIReady() {
                player = new YT.Player('player', {

                    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();
            }
        </script>
    </body>
