为什么我会得到：提供的索引超出界限错误？

Question

我开发的代码创建了一个接一个加载swfs的容器，当每个swf完成时它将卸载该swf。那么它会保存你已经加载的swf，并且下次启动时会加载最后一个swf。但遗憾的是我在我的输出:(得到这个

的SWFLoader 'loader2'（part2.swf）加载

的SWFLoader 'loader1'（part1.swf）加载

的SWFLoader 'loader4'（第四部分.swf文件）加载

的SWFLoader 'loader3'（part3.swf）加载

所有SWF加载

的SWFLoader 'loader1'（part1.swf）

的RangeError：错误＃2006：提供的索引超出范围。

在flash.display使用::级DisplayObjectContainer/getChildAt（） 在dblogo（）

如何摆脱提供的索引是出界失误？ 我新的AS3所以，如果可以把它简单... 下面是代码：

import flash.events.FullScreenEvent; 
import flash.display.StageScaleMode; 

stage.scaleMode = StageScaleMode.EXACT_FIT;

    swfs.load();

}

currentLoader.rawContent.stop(); 

//unload the swf that just played 

currentLoader.unload(); 

//set up and play the next swf 


initCurrentLoader(); 


} 
} 

this.addEventListener(Event.ENTER_FRAME, loadSWFs) 



function loadSWFs(e:Event):void{ 
load_btn.visible = false; 
swfs.load(); 
this.removeEventListener(Event.ENTER_FRAME, loadSWFs)

我想你应该与指数开始= 0，而不是-1：VAR loaderIndex：数= 0; 尝试并告诉我们结果
