1、界面:注册事件，并获取子窗体的值

//选择专题区域
private ?var ztqy:DBPJZTQY = null;
private function select_ztqy():void
{
? ?ztqy = new DBPJZTQY();
? ?ztqy.x = (this.stage.stageWidth-ztqy.width)/2;
? ?ztqy.y = (this.stage.stageHeight-ztqy.height)/2;
? ?ztqy.addEventListener("clickztqy",getParamztqy); //注意这里的时间名称
? PopupEffert.show(ztqy,this,true);
}
public function getParamztqy(e:Event):void
{
var s:String= ztqy.str_mc;
var ss:String= ztqy.str_dm;
}

<mx:Button click="select_ztqy()" />

2.界面：DBPJZTQY.mxml?
