youtube - YouTube Upload Widget/OnStateChange事件监听器

Question

我正在尝试使用onStateChange事件监听器对YouTube上载小部件进行调用，这取决于上载小部件的状态，但是我似乎无法使onStateChange事件监听器与上载小部件一起使用。请参阅下面的代码。奇怪的是，当我使用相同的技术为iframe播放器单独添加onStateChange侦听器时，它的效果就很好。有人有什么好主意吗？还是上传窗口小部件API只是 buggy ？

<script>    
var player;
var widget;
function onYouTubeIframeAPIReady() {
player1 = new YT.Player('player1', {
    events: {

      }
                       }
                       );

 widget = new YT.UploadWidget('widget', {
      events: {
        'onStateChange': onWidgetStateChange,
        'onUploadSuccess': onUploadSuccess,
        'onProcessingComplete': onProcessingComplete
      }
    });
  }

function onWidgetStateChange(event) {
    if (event.data == YT.UploadWidgetState.RECORDING) {
      player1.playVideo();
              }
}

function onUploadSuccess(event) {
    alert('Video ID ' + event.data.videoId + ' was uploaded and is currently being       processed.');
  }

function onProcessingComplete(event) {
    player = new YT.Player('player', {
      height: 390,
      width: 640,
      videoId: event.data.videoId,
      events: {

          }
    });
  }

我相信您的问题是您需要将event.data == YT.UploadWidgetState.RECORDING更改为event.data.state == YT.UploadWidgetState.RECORDING
进行更改时，我能够将一个jsfiddle组合在一起，几乎可以完成您想要的操作:http://jsfiddle.net/jeffposnick/yhWsG/35/
