Javascript快速静音youtube视频iframe的方法

Question

我正在寻找一种将视频静音的方法，除非用户取消静音。

<iframe id="video" src="https://www.youtube.com/embed/ShPQqM50Vz0?autoplay=1&showinfo=0&controls=0" frameborder="0" allowfullscreen></iframe>

我尝试使用此脚本，但没有任何显示

 <div id="player"></div>
<script>
      var tag = document.createElement('script');
      tag.src = "http://www.youtube.com/player_api";
      var firstScriptTag = document.getElementsByTagName('script')[0];
      firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

      var player;
      function onYouTubePlayerAPIReady() {
        player = new YT.Player('player', {
          playerVars: { 'autoplay': 1, 'controls': 1,'autohide':1,'wmode':'opaque' },
          videoId: 'ShPQqM50Vz0',
          events: {
            'onReady': onPlayerReady}
        });
      }

      function onPlayerReady(event) {
        event.target.mute();
      }
</script>
