twitter-bootstrap – Bootstrap Carousel中的Youtube iframe –

我希望能够检测用户何时点击控件,根据正在播放的当前视频创建播放器,并关闭该视频.在我看过的其他例子中,玩家是在onYoutubeIframeAPIReady函数中声明的,但我认为最好不要为页面上的每个视频动态创建玩家.现在,我收到了错误

Uncaught TypeError: Object #<T> has no method 'stopVideo'

当我点击旋转木马控件时.但是,如果我输入

player.stopVideo();

在Chrome javascript控制台中,它运行正常.我究竟做错了什么？

<script>
  var youtubeReady = false;

  function onYouTubeIframeAPIReady(){
    youtubeReady = true;
  }

  $('.carousel').on('slide',function(){
    if(youtubeReady){
      console.log("setting player");
      var iframeID = $(this).find('.active').find('iframe').attr("id");
      player = new YT.Player(iframeID); 
      player.stopVideo(); 
    }
  });
  </script>

示例轮播：

          <div class="carousel-inner 523">
          <div class="item active">
