Javascript 向文档加载时音频元素上的所有音频元素添加控件

您可以使用document.ready或window.load执行此操作

<script src="jQuery.js></script>
<script>
var a = document.getElementByTagName("audio");
a.controls = true;
</script>
<audio src ="one.mp3"></audio>
<audio src ="two.mp3"></audio>
<audio src ="three.mp3"></audio>
<audio src ="four.mp3"></audio>
<audio src ="five.mp3"></audio>

    $(document).ready(function(){
          $("#audio").each(function(){
       $(this).attr("controls","");
});
    });
