Youtube iFrame Api示例 - 错误：“JSON未定义”？

我想新的iFrame阿比examlpe @ http://code.google.com/apis/youtube/iframe_api_reference.html（下面的代码在这里..）Youtube iFrame Api示例 - 错误：“JSON未定义”？

万物工作prerfect在Chrome，Safari但在Firefox 3.0和IE6报告错误 - > JSON未定义的行：13 玩家仍在工作，但JavaScript的完全崩溃。

我试图让页面顶部json2.js库（http://www.json.org/）脚本，但没有效果更好。如何在这些旧浏览器上安排此JSON错误？

<html> 
    <body> 
    <!-- 1. The <div> tag will contain the <iframe> (and video player) --> 
    <div id="player"></div> 
    <script src="js/json2.js"></script> 
    <script language="javascript"> 
     // 2. This code loads the IFrame Player API code asynchronously. 
     var tag = document.createElement('script'); 
     tag.src = "http://www.youtube.com/player_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; 
     function onYouTubePlayerAPIReady() { 
     player = new YT.Player('player', { 
      height: '390', 
      width: '640', 
      videoId: 'u1zgFlCw8Aw', 
      playerVars: { 'autoplay': 1, 'controls': 0, 'showinfo': 0, 'loop': 1, 'rel' : 0, 'showsearch' : 0, 'enablejsapi' : 1}, 
      events: { 
      'onReady': onPlayerReady, 
      'onStateChange': onPlayerStateChange 
      } 
     }); 
     } 

     // 4. The API will call this function when the video player is ready. 
     function onPlayerReady(event) { 
     event.target.playVideo(); 
     } 


     function onPlayerStateChange(event) { 
     // 
     } 

    </script> 
    </body> 
</html>
