我需要一种获取视频的总时间长度和使用jQuery的当前时间的方式，并以几个< div>标签。
<div id="current">0:00</div> <div id="duration">0:00</div>
解决方法
HTML：
<video
id="video-active"
class="video-active"
width="640"
height="390"
controls="controls">
<source src="myvideo.mp4" type="video/mp4">
</video>
<div id="current">0:00</div>
<div id="duration">0:00</div>
JavaScript：
$(document).ready(function(){
$("#video-active").on(
"timeupdate",function(event){
onTrackedVideoFrame(this.currentTime,this.duration);
});
}
function onTrackedVideoFrame(currentTime,duration){
$("#current").text(currentTime);
$("#duration").text(duration);
}
笔记：
Every 15 to 250ms,or whenever the MediaController’s media controller
position changes,whichever happens least often,the user agent must
queue a task to fire a simple event named timeupdate at the
MediaController.
