Question

我正在开发一个Phonegap应用程序。我想在页面中播放Youtube视频以及一些文本内容。我使用了iframe，视频正在播放，暂停，全屏但我只能听到声音。没有视频只有黑屏。

iframe class="embed-responsive-item" width="560" height ="315" src="https://www.youtube.com/embed/VIDEO_ID" allowfullscreen="allowfullscreen" frameBorder="0"

请帮我解决这个问题。提前谢谢。

Answer 1

Youtube正在提供youtube播放器API。我在phonegap API中使用了这个API，它的工作正常。这是代码。

<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>

并在html文件中

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

它在我的phonegap应用程序中运行良好。你可以试试这个。
