巧用Flash的Media组件实现多首mp3连播

function init(){
flagNum = 1;
//播放歌曲的标示
mp3Num = 0;
attachController();
};
//将MediaController和MediaDisplay组件载入舞台并初始化
function attachController(){
//将MediaDisplay组件载入舞台并给定义实例名 "mp3Container" + flagNum
  _root.attachMovie("MediaDisplay","mp3Container" + flagNum,2);
  //设置组件初始参数
  with(_root["mp3Container" + flagNum]){
   _x = 250;
   _y = 0;
   setMedia(myArray[mp3Num],"MP3");
}
//将MediaController组件载入舞台并给定义实例名 "mp3Controller" + flagNum
_root.attachMovie("MediaController","mp3Controller" + flagNum,1);
//设置组件初始参数
with(_root["mp3Controller" + flagNum]){
    _x = 0;
    _y = 0;
   activePlayControl = false;
   controllerPolicy = "on";
   //将MediaController和MediaDisplay组件相关联
   associateDisplay(_root["mp3Container" + flagNum]);
  };
};
function playNext(){
//将MediaController和MediaDisplay组件从舞台上删除
    _root["mp3Controller" + flagNum].removeMovieClip();
    _root["mp3Container" + flagNum].removeMovieClip();
    flagNum += 1;
    mp3Num += 1;
    //如果播放到歌曲的最后一首，将mp3Num = 0，意为将从头开始播放
    if(mp3Num == mp3Total) mp3Num = 0;
    //重新载入MediaController和MediaDisplay组件，并给一新的实例名
       attachController();
       //因为每播放完一首歌曲后MediaController和MediaDisplay组件从舞台上被卸载
       //然后又重新载入MediaController和MediaDisplay组件并给了另外一个实例名
       //所以要重新向注册的监听器广播事情
       _root["mp3Container" + flagNum].addEventListener("complete", myListener);
};

stop();
//数组myArray用来存储 载入的XML文档中的歌曲名称
var myArray = new Array();
//歌曲的总数
var mp3Total:Number;
var myXml = new XML();
myXml.ignoreWhite = true;
myXml.load("mp3list.xml");
myXml.onLoad = function() {
var e = myXml.firstChild.childNodes;
mp3Total = e.length;
for (var i = 0; i<mp3Total; i++) {
myArray.push(e[i].attributes["title"]);
}
init();
_root["mp3Container"+flagNum].addEventListener("complete", myListener);

var myListener = new Object();
myListener.complete = function(eventObject) {
playNext();
};
