<p>该实例中，我们使用了 HTML DOM 为 audio 元素添加 "ontimeupdate" 事件。
在用户开始播放视频，或者移动音频的播放位置时触发函数，并显示视频的播放位置。</p>
<audio id="myAudio" controls>
  <source src="/statics/demosource/horse.ogg" type="audio/ogg">
  <source src="/statics/demosource/horse.mp3" type="audio/mpeg">
   您的浏览器不支持 audio 元素。
</audio>
<p>播放位置: <span id="demo"></span></p>
<script>
// 获取 id="myAudio" 的 audio
var aud = document.getElementById("myAudio");
// 为 audio 元素添加 ontimeupdate 事件，并在播放位置改变时执行函数 
aud.ontimeupdate = function() {myFunction()};
function myFunction() {
    // 显示 id="demo" 的 &lt;p&gt; 元素中音频的播放位置
    document.getElementById("demo").innerHTML = aud.currentTime;
}
