<script language="javascript">

    var wmp=this.document.getelementbyid("player");

    //播放

    function playthis(url)

    {           

       wmp.url = url;

       wmp.controls.play();

如何播放一个音乐列表?

思路:播放一个音乐列表,需要实现两个目的,一是循环,二是判断是否当前歌曲播放完成.只有当前歌曲播放完成后才进行循环.实现检测.

   var i=0;

   playthis(firstmusic)

   //实时检测器,间隔时间为1秒

   d=setinterval(function shwotimer()

   {  

        if(wmp.playstate==1) 

        { 

            if(i>=soundarray.length)

            {       

                //当播放所有完成后清空循环                             

                clearinterval(d);

            }

            else

            {    

                 //当播放完成后播放下一首

                 playthis(url); 

        }

  }

  ,1000);

如有其它控制需要,如暂停,可设置一个标识,即当前暂停,则下一步为播放,反之亦然

  var pauseflag=0;

  function command_pause()

  {

      if(pauseflag==0)

      {

          wmp.controls.pause();

      }

      else

          wmp.controls.play();                           

      pauseflag=pauseflag==1?0:1;
