js的一个视频播放路径问题，换成txt文件，读取不到菜单路径了~

Question

 var s = new SWFObject("D:/flashPlay/flvplayer/flvplayer.swf","preview","240","240","7");
            s.addParam("allowfullscreen","true");
            //s.addVariable("file","D:/flashPlay/flvplayer/狼牙.flv");
              s.addVariable("file","D:/flashPlay/flvplayer/playlist.txt"); s.addVariable("autostart","true");
s.addVariable("repeat","list");
            s.addVariable("width","240");
            s.addVariable("height","240");
            s.addVariable("displayheight","175");
            s.write("player");我这里 单播放狼牙 没问题
 我建立一个playlist.txt文件  然后里面 写    /狼牙.flv
s.addVariable("file","D:/flashPlay/flvplayer/playlist.txt");这样的话 就找不到路径了  大哥们帮我看下
