AS3: setChildIndex of targetSection + "_mc“to FRONT / accessing on alpha:0 MC

Question

我目前正在使用AS3 &Greensock的TimelineMax在闪存CS5中制作一个定制应用程序。

导航基于Snorkl.TV Bullet proof portfolio，它使用TimeLineMax跳到时间线中的标签，并使用alpha跳到适当的MC中。所有的MC Garment_mc，Size_mc，Design_mc，Ink_mc，Options_mc，Checkout_mc都坐在舞台上不同层的同一空间上，当他们的按钮被点击时，从x:-100开始补间。

这意味着当SWF发布在最上面的层并且MC覆盖其他MC时，当您导航到较低的MC时，它们显示在alpha:0 MC的下面，因此最上面的MC的按钮/功能仍然可以点击并影响之前的选择(选择服装，下一节，单击该MC上的某些东西，它会注册在最上面的MC上)。

我需要NavClick函数包含如下内容...setChildIndex(targetSection + "_mc"，0)，但我得到了1067:隐式强制错误。

有没有人能给出什么建议？或者我应该从这里做什么？我正在赶着我最后的交接日期，所以任何帮助都是很好的，谢谢！

启动代码。

// all the section clips are fully visible on the stage
//we don't want to see them when the swf starts
//set up an array of section clips so that we can start them all with alpha=0;
var Panel_clips = [Garment_mc,Size_mc,Design_mc,Ink_mc,Options_mc,Checkout_mc];

for (var j:Number = 0; j < Panel_clips.length; j++)
{
    Panel_clips[j].alpha = 0;
}

在navClick function中，更改以下行：

targetSection = e.target.ID;

如下所示：

targetSection = e.target;

因为作为第一个参数的setChildIndex函数需要子电影本身，而不是他的名字/id。

编辑:在你的情况下，可能是你也应该尝试一下：

setChildIndex( getChildByName(e.target.ID + "_mc"),0);
