从单独的功能暂停YouTube视频?

我为YouTube API制作了暂停按钮。如果它在创建视频的同一个函数中,它可以工作,但我需要它在一个单独的函数中。

http://jsfiddle.net/czvufy75/8/

$(function() {
    // 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;
      onYouTubeIframeAPIReady = 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();
      }

        $('.trigger').click(function(){
            //this works
            player.pauseVideo()
        });
});

$(function() {
    $('.trigger2').click(function(){
            // this does not work
            player.pauseVideo()
        });
});

它没有用,因为player在第二个函数中未定义。

您可以在函数之外定义它。
