flash课件怎么实现点击跳转到不同的题目?

var numAry:Array=[2,3,4,5,6,7,8];var index:int=0;var idAry:Array=new Array();mc.gotoAndStop(1);idAry=GetRandomAry(numAry);btn.addEventListener(MouseEvent.CLICK,GetNextFrame);function GetNextFrame(e:MouseEvent):void{if(index<idAry.length){mc.gotoAndStop(idAry[index]);index++;}else{mc.gotoAndStop(mc.totalFrames);}}function GetRandomAry(ary:Array):Array{var tempAry:Array=new Array();var tempAry2:Array=ary;while(tempAry2.length>0){var temp:int=int(Math.random()*10000)%tempAry2.length;tempAry.push(tempAry2[temp]);tempAry2.splice(temp,1);}return tempAry;}
