flash as3 动态循环加载库中元件到舞台，并控制

import flash.events.MouseEvent;var i:int;var array:Array = new Array();var mcc:mclass;var num:int;num = 4;for (i = 0; i<num; i++){mcc  = new mclass();//创建实例 mcc.x = i * 120;mcc.y =300;//设置mcc的坐标 this.addChild(mcc);//加入显示列表 ;array.push(mcc);//加入数组 ;array[i].a.text = '动态元件';array[i].buttonMode=true;array[i].mouseChildren=false;array[i].addEventListener(MouseEvent.CLICK, mcfunc);    function mcfunc(e:MouseEvent){trace('鼠标');e.currentTarget.y-=10;}
