AS3如何返回父级的其中一帧

AS3如何返回父级的其中一帧

在mc2的帧上写如下代码：
closeA.addEventListener(MouseEvent.CLICK, gotoFrameA);
function gotoFrameA(evt:MouseEvent):void{
MovieClip(this.parent).gotoAndStop(5);
}
closeB.addEventListener(MouseEvent.CLICK, gotoFramB);
function gotoFrameB(evt:MouseEvent):void{
MovieClip(this.parent).gotoAndStop(7);
}

closeC.addEventListener(MouseEvent.CLICK, gotoFrameC);
function gotoFrameA(evt:MouseEvent):void{
MovieClip(this.parent).gotoAndStop(10);
}

在mc2的任意一个图层的第一帧中添加如下代码：
closeA.addEventListener(MouseEvent.CLICK, gotoFrame); //给三个按钮添加监听事件
closeB.addEventListener(MouseEvent.CLICK, gotoFrame); //响应事件为鼠标点击
closeC.addEventListener(MouseEvent.CLICK, gotoFrame); //响应函数为gotoFrame

function gotoFrame(event:MouseEvent):void
{
if(event.currentTarget === closeA) //判断当前事件对象是否全等与 closeA 按钮
{
this.parent)gotoAndStop(5);
}
else if(event.currentTarget === closeB)
{
this.parent)gotoAndStop(7);
}
else if(event.currentTarget === closeC)
{
this.parent)gotoAndStop(10);
}
}
