这是我的游戏关卡选择器。你可以选择1-8级，我需要知道点击了哪一个。e.target 除了对象的名称之外并没有给我太多信息。我需要知道数组中的位置或图片的名称，以便知道要加载哪个级别。

package

我会做这样的事情：

//...
private function init(e:Event = null):void 
{
    //...
    for (var i:int = 1; i < 9; i++) 
    {
        //...
        myArraySprites[i] = new Sprite();
        myArraySprites[i].addChild(myArrayBitmaps[i]);
        //...
        stage.addChild(myArraySprites[i]);

        myArraySprites[i].addEventListener(MouseEvent.CLICK, removeThis);


        }
    }
}
private function removeThis(e:MouseEvent):void
{
    var clickTarget:int = myArraySprites.indexOf(e.currentTarget);
    trace("Clicked sprite (id): " + clickTarget);
}
