我想转换成字符串数组影片剪辑这已经在舞台上存在的名称。

I am trying to convert an array of string to MovieClip names which already exist on stage.

这是我怎么做的，但美国能源部鼻涕似乎工作。 我有11个影片剪辑在舞台上。它们的实例名是bmc1，BMC2等。 所有这些BMC影片剪辑是一个名为bars_mc夹里。因此，这是我如何编码它现在。

THis is how I am doing it but doe snot seem to work. I have 11 movieclips on stage. THeir instance names are "bmc1", "bmc2" and so on. All these BMC movie clips are inside a clip called "bars_mc". So this is how I am coding it right now.

var myBtnArray = ['bmc1', 'bmc2', 'bmc3', 'bmc4', 'bmc5', 'bmc6', 'bmc7', 'bmc8', 'bmc9', 'bmc10', 'bmc11'];
for each (var btn in myBtnArray){
    bars_mc.MovieClip(getChildByName(btn)).gotoAndPlay('open');
}

这是行不通的。 我曾尝试这样做的：

This does not work. I have tried doing:

this[btn]

这也没有工作。 这是codeD在AS 3.0。

That also didnt work. This is being coded in AS 3.0.

需要有人T0帮我找出正确的方式将字符串转换为影片剪辑。

推荐答案

我认为这个问题很可能是你已经添加了影片剪辑投错了地方，因为虽然有对对象bars_mc属性影片剪辑。

I think the problem is likely that you've added the MovieClip cast in the wrong place, as though there were a property MovieClip on the object bars_mc.

这个例子涉及一个额外的行，但应该是一个更清楚一点：

This example involves an extra line but should be a bit clearer:

var myBtnArray = ['bmc1', 'bmc2', 'bmc3', 'bmc4', 'bmc5', 'bmc6', 'bmc7', 'bmc8', 'bmc9', 'bmc10', 'bmc11'];
for each (var btn:String in myBtnArray) {
    var btnClip:MovieClip = bars_mc[btn] as MovieClip;
    btnClip.gotoAndPlay('open');
}

和一个版本更接近你原来是：

And a version closer to your original would be:

var myBtnArray = ['bmc1', 'bmc2', 'bmc3', 'bmc4', 'bmc5', 'bmc6', 'bmc7', 'bmc8', 'bmc9', 'bmc10', 'bmc11'];
for each (var btn:String in myBtnArray) {
    MovieClip(bars_mc[btn]).gotoAndPlay('open');
}
