您可以添加一个“已结束”的事件侦听器作为第一个参数

像这样：

<video src="video.ogv" id="myVideo">
  video not supported
</video>

<script type='text/javascript'>
    document.getElementById('myVideo').addEventListener('ended',myHandler,false);
    function myHandler(e) {
        // What you want to do after the event
    }
</script>

这是一种在视频结束时触发的简单方法 .

<html>
<body>

    <video id="myVideo" controls="controls">
        <source src="video.mp4" type="video/mp4">
        etc ...
    </video>

</body>
<script type='text/javascript'>

    document.getElementById('myVideo').addEventListener('ended', function(e) {

        alert('The End');

    })

</script>
</html>

在'EventListener'行中，将'ended'替换为'pause'或'play'来捕获这些事件 .

您可以添加监听器所有视频事件，其中包括 ended, loadedmetadata, timeupdate ，其中 ended 函数在视频结束时被调用

$("#myVideo").on("ended", function() {
   //TO DO: Your code goes here...
      alert("Video Finished");
});

$("#myVideo").on("loadedmetadata", function() {
      alert("Video loaded");
  this.currentTime = 50;//50 seconds
   //TO DO: Your code goes here...
});


$("#myVideo").on("timeupdate", function() {
  var cTime=this.currentTime;
  if(cTime>0 && cTime % 2 == 0)//Alerts every 2 minutes once
      alert("Video played "+cTime+" minutes");
   //TO DO: Your code goes here...
  var perc=cTime * 100 / this.duration;
  if(perc % 10 == 0)//Alerts when every 10% watched
      alert("Video played "+ perc +"%");
});

<!DOCTYPE html>

      <source src="your_video_file.mp4" type="video/ogg">

在"I want to roll my own controls"部分的Opera Dev网站上查看这篇Everything You Need to Know About HTML5 Video and Audio帖子 .

这是相关部分：
```
<video src="video.ogv">
     video not supported
</video>
```
然后你可以使用：
```
<script>
    var video = document.getElementsByTagName('video')[0];

    video.onended = function(e) {
      /*Do things here!*/
    };
</script>
```
onended 是所有媒体元素上的HTML5标准事件，请参阅HTML5 media element (video/audio) events文档 .

这是一个完整的例子，我希望它有帮助=） .

<!DOCTYPE html> 
<html> 
<body> 

<video id="myVideo" controls="controls">
  <source src="your_video_file.mp4" type="video/mp4">
  <source src="your_video_file.mp4" type="video/ogg">
  Your browser does not support HTML5 video.
</video>

<script type='text/javascript'>
    document.getElementById('myVideo').addEventListener('ended',myHandler,false);
    function myHandler(e) {
        if(!e) { e = window.event; }
        alert("Video Finished");
    }
</script>
</body> 
</html>
