音乐连播功能主要用到的 JS对WMP的操作

//基本属性　
wmp.URL:String; //指定媒体位置，本机或网络地址
wmp.uiMode:String; //播放器界面模式，可为Full, Mini, None, Invisible
wmp.playState:integer; //播放状态，1=停止，2=暂停，3=播放，6=正在缓冲，9=正在连接，10=准备就绪
wmp.enableContextMenu:Boolean; //启用/禁用右键菜单
wmp.fullScreen:boolean; //是否全屏显示

//播放器常用控制
wmp.controls.play; //播放
wmp.controls.pause; //暂停
wmp.controls.stop; //停止
wmp.controls.currentPosition:double; //当前进度
wmp.controls.currentPositionString:string; //当前进度，字符串格式。如“00:23”
wmp.controls.fastForward; //快进
wmp.controls.fastReverse; //快退
wmp.controls.next; //下一曲
wmp.controls.previous; //上一曲

//播放器常用设置
wmp.settings.volume:integer; //音量，0-100
wmp.settings.autoStart:Boolean; //是否自动播放
wmp.settings.mute:Boolean; //是否静音
wmp.settings.playCount:integer; //播放次数
wmp.settings.balance = -100; //(左声)
wmp.settings.balance=100; //(右声)
wmp.settings.balance=0; //(全声)

//常用当前媒体属性
wmp.currentMedia.duration:double; //媒体总长度
wmp.currentMedia.durationString:string; //媒体总长度，字符串格式。如“03:24”
wmp.currentMedia.getItemInfo(const string); //获取当前媒体信息
//"Title"=媒体标题     "Author"=艺术家     "Copyright"=版权信息
//"Description"=媒体内容描述     "Duration"=持续时间（秒）
//"FileSize"=文件大小     "FileType"=文件类型     "sourceURL"=原始地址
wmp.currentMedia.setItemInfo(const string); //通过属性名设置媒体信息
wmp.currentMedia.name:string; //同currentMedia.getItemInfo("Title")

wmp.network.bufferingProgress; //缓冲百分比
wmp.network.downloadProgress; //下载百分比
 
较全面的页面参数设置

<script language="javascript">
    var WMP=this.document.getElementById("Player");

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;                  
  }
