AS3简单mp3播放器实例

下午抽了点时间给自己的blog写了一个MP3简单的播放器,用的是一个免费的mp3类,老外写的,没有仔细看,不过用起来蛮方便,发出来给大家做个参考!!

以下是代码,老外的代码就不贴出来了!!又兴趣下载源码看吧!!

 import flash.net.URLLoader;
 import flash.net.URLRequest;
 import flash.events.Event;
 import com.arpitonline.controls.mp3Playback.MP3Playback;
 import com.arpitonline.controls.mp3Playback.PlaybackProgressEvent;
 
 var xmlUrl:String;
 xmlUrl = loaderInfo.parameters["url"];
 //xmlUrl = "mp3.xml";
 var Isplay:String;
 Isplay = loaderInfo.parameters["isplay"];
 //Isplay = "2";
 var playconut:int = 0;
 var loadXML:URLLoader=new URLLoader();
 var arrList:Array = new Array();
 var mp3Playback = new MP3Playback();
 var myRequest:URLRequest = new URLRequest(xmlUrl);
 loadXML.load(myRequest);
 loadXML.addEventListener(Event.COMPLETE,loadComplete);
 mp3Playback.addEventListener(PlaybackProgressEvent.PLAYBACK_PROGRESS, onPlaybackProgress);
 mp3Playback.addEventListener(MP3Playback.SONG_COMPLETE, onSongComplete);
 playbtn.addEventListener(MouseEvent.CLICK ,playbtnClick);
 stopbtn.addEventListener(MouseEvent.CLICK ,stopbtnClick);
 function onSongComplete(event:Event):void{
    if(++playconut==arrList.length)
    {playconut=0};
                mp3Playback.source = arrList[playconut].url;
            }
 function stopbtnClick(e:MouseEvent)
 {
  mp3Playback.stop();
  if(Isplay =="1")
  {
   Isplay ="2";
   playbtn.play();
  }
 }
 function playbtnClick(e:MouseEvent)
 {
  if(Isplay =="1")
  {
   Isplay ="2";
   mp3Playback.pause();
  }
  else
  {
   Isplay="1";
   if(mp3Playback.enabled)
   {
   mp3Playback.play();
   }
   else
   {
     mp3Playback.source = arrList[playconut].url;
   }
  }
  playbtn.play();
 }
 
 function loadComplete(e:Event)
  {
   
   var strxml:XML =new XML( loadXML.data) ;
   var max:int = strxml.@length ;
   for(var i:int=0;i<max;i++)
   {
    arrList[i]={title:strxml.mp3[i].title,url:strxml.mp3[i].url,description:strxml.mp3[i].description}
   }
   if(Isplay=="1")
   {
    mp3Playback.source = arrList[0].url;
    playbtn.play();
   }

   
  }
   function onPlaybackProgress(event:PlaybackProgressEvent):void{
    var p:Number = isNaN(event.playheadPercent)? 0:event.playheadPercent;
     
                Pbar.graphics.clear();
    Pbar.graphics.beginFill(0x000000);
    Pbar.graphics.drawRect(0,0,Math.floor(p*100),3);
  }

这个是xml

xml里的东西并没有都用到,这个只是方便扩展!!  xml地址 和 是否直接播放的参数是直接传进去滴!! 

<param value="/mp3/mp3.swf?url=/mp3/mp3.xml&amp;isplay=2" name="movie" /> 嵌入flash时注意参数

写的时间很短不知道有没有bug, 代码写的比较随意!!
