如何添加youtube外部取消静音

Question

我正在尝试按下按钮以取消静音但无法执行它。我最初的计划是做一个切换声音，但我希望先发出声音

 
   
    
      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', {
          height: '600',
          width: '100%',
          playerVars: { 'autoplay': 1, 'controls': 0,'autohide':1,'wmode':'opaque' },
          videoId: 'W83b4HoPdFo',
          events: {
            'onReady': onPlayerReady}
        });
      }

      // 4. The API will call this function when the video player is ready.
      function onPlayerReady(event) {
        event.target.mute();
      }
  
  
  
       $('#mutevideo').on('click', function(){
                player.unmute();        
       
        
      });
  
  
  

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="player"></div>
<a href="#" id="mutevideo">Sound On</a>

Answer 1

你可以使用，

 player.unMute();

而不是

 player.unmute();
