youtube iFrame嵌入的參考API未加載iFrame

Question

我已使用代碼https://developers.google.com/youtube/iframe_api_reference#Getting_Started。我已經複製了上述url中提供的代碼。但是，它給了我一個空白頁面。

<div id="player"></div> 
    <script> 
     // 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; 
     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(); 
     } 
    </script> 

任何人都可以請幫我解決這個問題嗎？

這段代碼看起來不錯。你把它粘貼在什麼地方？也許這是一個無關的語法錯誤...
