检查YouTube视频是否正在播放并运行脚本

Question

我在WordPress中嵌入了以下视频

<iframe id="video" width="640" height="360" src="http://www.youtube.com/embed/xxxxxx?enablejsapi=1" frameborder="0" allowfullscreen></iframe>

它在SlideDeck滑块内,我想在有人点击视频时停止.我无法弄清楚如何获得这行代码

self.pauseAutoPlay = true;

在视频播放时运行.

我非常需要一些帮助.

编辑:因为我不是最终用户.我需要一些适用于YouTube默认嵌入代码的内容.

Answer 1

您需要使用YouTube iFrame API.请记住,我只知道Javascript的基础知识等等,所以这可能会更有效率.

他们像往常一样嵌入你的iframe

<iframe id="player" width="640" height="360" src="http://www.youtube.com/embed/TJ2X4dFhAC0?enablejsapi" frameborder="0" allowfullscreen></iframe>

但有一些变化.它需要有一个ID,"播放器",你需要附加?enablejsapi到源URI的末尾.

然后,您需要运行以下脚本来加载API JS以及创建播放器

// 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',
      events: {
        'onReady': onPlayerReady,
        'onStateChange': onPlayerStateChange
      }
    });
  }

请注意,它new YT.Player('player'应与您的iframe ID videoId: 'u1zgFlCw8Aw'匹配,并且应与src URI匹配.

在此之后,您将能够运行像这样的脚本

var myPlayerState;
      function onPlayerStateChange(event) {
        if (event.data == YT.PlayerState.PLAYING && !done) {
          // DO THIS
        }
        myPlayerState = event.data;
      }

if (myPlayerState == 1){
  // PAUSE SLIDER
}

Answer 2

你需要直接用flash嵌入youtube:

之后,您可以使用youtube javascript API.

你的代码可能是这样的:

<script type="text/javascript" src="swfobject.js"></script>    
<div id="ytapiplayer">
You need Flash player 8+ and JavaScript enabled to view this video.
</div>

<script type="text/javascript">

var params = { allowScriptAccess: "always" };
var atts = { id: "myytplayer" };
swfobject.embedSWF("http://www.youtube.com/v/VIDEO_ID?enablejsapi=1&playerapiid=ytplayer&version=3",
                   "ytapiplayer", "425", "356", "8", null, null, params, atts);


var player;

function onytplayerStateChange(newState) {
    if (newState == 1)
        callPlay();
    else if (newState == 2)
        callPause();
}

function callPlay() {
    //video is play
}

function callPause() {
    //video is paused
}

</script>
