YouTube Iframe API - OnStateChange突然不工作

Question

直到美国东部时间下午6点左右，下面的代码工作得很好，但现在由于某种原因，onStateChange没有触发。我在多个浏览器上尝试过，并让朋友检查过。看到什么明显的错误了吗?

<div id="video">
  <div id="player_wrap">
    <div id="player"></div>
  </div>
</div>
   <script>
    var tag = document.createElement("script");
    tag.src = "http://www.youtube.com/iframe_api";
    var firstScriptTag = document.getElementsByTagName("script")[0];
    firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
    function onYouTubeIframeAPIReady() {
    var player;
        player = new YT.Player("player", {
          width: 640,
          height: 400,
          videoId: "MbfsFR0s-_A",
          events: { 
            'onReady': onPlayerReady, 
            'onStateChange': onPlayerStateChange          
          }
        });
      }
function onPlayerReady() {
alert ("player ready"); 
}

function onPlayerStateChange(event) {
alert ("something happened"); 
}

Answer 1

这是iFrame Player API的临时问题。你可以在这里阅读:https://code.google.com/p/gdata-issues/issues/detail?id=4706

Jeff Posnick在这里发布了一个临时解决方案:http://jsfiddle.net/jeffposnick/yhWsG/3/

基本上，您只需要在onReady事件中添加事件侦听器(只是临时修复):

function onReady() {
    player.addEventListener('onStateChange', function(e) {
        console.log('State is:', e.data);
    });
}

张贴在这里的解决方案很好，真的很干净:

player = new YT.Player(element,{
    events: {
        onReady: function(){
            /*
            Do your stuff
            */
            // Attach a void function to the event
            player.addEventListener('onStateChange',function(){});
        },
        onStateChange: function(){
        // Actual function that gets executed during the event
        }
    }
});
