How can I listen for the "timeupdate" event from my video.js player?
提问by coyote
While I have been able to listen for the "timeupdate" event with a vanilla HTML5 player, I can't seem to get it to work with video.js.
虽然我已经能够使用普通 HTML5 播放器收听“timeupdate”事件，但我似乎无法让它与 video.js 一起使用。
Here's my code:
这是我的代码：
<!DOCTYPE html>
<html>
<head>
<link href="video-js.css" rel="stylesheet">
<script src="video.js"></script>
<script src="jquery.min.js"></script>
</head>
<body>
<video id="testvid" class="video-js vjs-default-skin" controls width="640" height="480" data-setup='{}'>
<source src="testvideo.mp4" type="video/mp4">
</video>
</body>
</html>
<script>
videojs('testvid').ready(function(){
var myPlayer = this;
$(myPlayer).bind('timeupdate', function(){
console.log('the time was updated to: ' + this.currentTime);
});
});
</script>
Am I misunderstanding a basic way that video.js operates?
我是否误解了 video.js 的基本操作方式？

You actually CAN register events in callback of ready(), and it is better solution because in previous one registration of event still could be finished after ready(). Use following snippet:
实际上你可以在ready()的回调中注册事件，这是更好的解决方案，因为在前一个事件注册在ready()之后仍然可以完成。使用以下代码段：
videojs('example_video_1').ready(function () {
this.on('timeupdate', function () {
console.log(this.currentTime());
})
});

I have to add the event listener before the video loads. I solved the problem by changing the script to:
我必须在视频加载之前添加事件侦听器。我通过将脚本更改为：
<script>
$('#testvid').on('timeupdate', function(){
console.log('the time was updated to: ' + this.currentTime);
});
videojs('testvid').ready(function(){
var myPlayer = this;
});
</script>
