<p>该实例中，我们使用了 addEventListener() 方法为 video 元素添加 "ontimeupdate" 事件。
在用户开始播放视频，或者移动视频的播放位置时触发函数，并显示视频的播放位置。</p>
<video id="myVideo" controls>
  <source src="/statics/demosource/mov_bbb.mp4" type="video/mp4">
  <source src="/statics/demosource/mov_bbb.ogg" type="video/ogg">
  您的浏览器不支持 HTML5 video 标签
</video>
<p>播放位置： <span id="demo"></span></p>
<script>
// 获取 id="myVideo" 的 video 元素
var vid = document.getElementById("myVideo");
// 为 video 元素添加 ontimeupdate 事件，如果当前播放位置改变则执行函数  
vid.addEventListener("timeupdate", myFunction);
function myFunction() {
    // 显示 id="demo" 的 p 元素中视频的播放位置
    document.getElementById("demo").innerHTML = vid.currentTime;
}
