在 google 提供的示例中，我可以在哪里调用 widget.setVideoTitle(title)：
<div id="widget"></div>
<div id="player"></div>
<script>
// 2. Asynchronously load the Upload Widget and Player API code.
var tag = document.createElement('script');
tag.src = "//www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// 3. Define global variables for the widget and the player.
// The function loads the widget after the JavaScript code
// has downloaded and defines event handlers for callback
// notifications related to the widget.
var widget;
var player;
function onYouTubeIframeAPIReady() {
widget = new YT.UploadWidget('widget', {
width: 500,
events: {
'onUploadSuccess': onUploadSuccess,
'onProcessingComplete': onProcessingComplete
}
});
}
// 4. This function is called when a video has been successfully uploaded.
function onUploadSuccess(event) {
alert('Video ID ' + event.data.videoId + ' was uploaded and is currently being processed.');
}
// 5. This function is called when a video has been successfully
// processed.
function onProcessingComplete(event) {
player = new YT.Player('player', {
height: 390,
width: 640,
videoId: event.data.videoId,
events: {}
});
}
</script>
附言。onProcessingComplete 根本不起作用，如果评论它对上传没有任何影响，所以我在处理时没有收到任何返回的消息.....
