我正在使用 Wordpress,并且我已经有很多嵌入了 Youtube 视频的帖子。如何在不重写所有帖子的情况下检测视频何时停止播放?

我知道你可以使用 Youtube player API(下)

<!DOCTYPE html>
<html>
  <body>
    <!-- 1. The <iframe> (and video player) will replace this <div> tag. -->
    <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>
  </body>
</html>

但在我所有的帖子中,我都嵌入了这样的视频:

<iframe width="640" height="390" frameborder="0" type="text/html" src="http://www.youtube.com/embed/u1zgFlCw8Aw?enablejsapi=1"></iframe>

这是我到目前为止所做的。-(关联)

onYouTubePlayerReady();

function onYouTubePlayerReady() {
  //ytplayer = document.getElementById(playerId);
    ytplayer = $('iframe[src^="http://youtube.com/embed/"]');
    ytplayer.addEventListener("onStateChange", "onytplayerStateChange");
}

function onytplayerStateChange(newState) {
   if(newState==YT.PlayerState.ENDED){
        alert('stop');
   }
}

我不想浏览我所有的帖子并一一编辑。有没有办法可以对所有嵌入式视频进行全局挂钩?

据我所知,当您已经使用 iframe 嵌入视频时,您无法使用 Youtube API 来检测播放器更改。

所以一种解决方案是使用 jQuery 找到 iframe,从 src 属性中获取视频 id,删除 iframe,然后让 Youtube API 再次将视频嵌入到同一位置。我已经重写了您的代码,这应该可以帮助您入门。您可以将代码插入某种全局模板中,以便它适用于每个博客项目。

(我无法让它在 FiddleJS 上工作,但它可以很好地将代码保存为本地文件。)

    <html>
    <body>
    <iframe width="640" height="390" frameborder="0" type="text/html" src="http://www.youtube.com/embed/u1zgFlCw8Aw?enablejsapi=1"></iframe>


    <script type="text/javascript">

    function getVideoID(){
        var videoIframe =  $('iframe');
        var videoURL = videoIframe.attr('src');
        var id = videoURL.split("/")[4].split("?")[0];
        videoIframe.after('<div id="player"></div>');
        videoIframe.remove();
        return (id);
    }

    // 3. This function creates an <iframe> (and YouTube player)
    //    after the API code downloads.
    var player;
    function onYouTubeIframeAPIReady() {
       var videoID = getVideoID();
       player = new YT.Player('player', {
       height: '195',
       width: '320',
       videoId: videoID,
       events: {
          'onReady': onPlayerReady,
          'onStateChange': onPlayerStateChange
           }
        });

          function onPlayerReady(event) {
              event.target.playVideo();
          }

          function onPlayerStateChange(event) {
           var state = event.target.getPlayerState();
            if (state === 2) {
                alert("Paused");
            }
             else if (state === 0) {
                alert("Ended");
             }
            }
          }
    </script>
