消除儿童增加活力的一些问题
原标题:Some problems regarding removing a child added dynamically

我有这一职能,我希望获得一部电影剪辑(功能目标),并将其改为另一部电影。 问题是,在装满新车之前,这显然排除了电影剪辑。

var changePeca:Loader = new Loader;
var changeLoad:URLRequest = new URLRequest(e.target.name.substr(0,4)+".png");
changePeca.load(changeLoad);

e.target.removeChildAt(0);
e.target.addChild(changePeca);

我知道,我必须使用<代码>。 活动:COMPLETE 是的,但我是如何说哪些电影可以删除的,因为我可以再使用<条码>。

最佳回答

"The problem is that it obviously removes the movie clip before the new one is loaded."

因为你们的法典这样说! 你们需要补充活动听众,如果 st子被装上,则会对其进行检查。

private var holderMC:Sprite;
private var imageLoader:Loader;

private  function load(e:Event):void
{
    holderMC = e.target as Sprite // or something else you have there, just store it.
    imageLoader = new Loader ();
    imageLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, handleLoadComplete)
    imageLoader.load(new URLRequest(e.target.name.substr(0, 4) + ".png"));
}

private function handleLoadComplete(e:Event):void 
{
    if(holderMC.numChildren > 0)
        holderMC.removeChildAt(0);

    holderMC.addChild(imageLoader.content)
}
