我把问题移到了这个新问题上.我正在尝试在加载图像时删除loading111. 我正在尝试做的是，将loading111添加到每个Bolder中，并且在加载图像时，我删除了loading111(这只是一个显示正在加载的标志).
I moved the question to this new one. I am trying to remove the loading111 when the image is loaded. What i am trying to do, to add loading111 into each Bolder, and when the image is loaded, and i remove the loading111(which is just a sign showing loading).
感谢您的帮助！

推荐答案
removeChild(loading111);尝试从这个"类而不是Boulder类对象中删除最后创建的加载程序图标.
removeChild(loading111); tries to remove last created loader icon from "this" class and not from Boulder class object.
您应该将图像和其他显示对象存储在Vector之类的容器中，并通过ID对其进行访问.
You should store your images and other display objects in come container like Vector and access them by id.
但是有一个粗略的解决方案，如果您粗心的话，可能会导致一些问题:
But there is rough solution, which may cause you some problems if you will be careless:
function onImageLoaded(e:Event):void {
DisplayObjectContainer(e.target.loader).parent.removeChildAt(0);
或者如果它不起作用，则:
or if it does not work then:
function onImageLoaded(e:Event):void {
var boulderOfThisImage:DisplayObjectContainer = DisplayObjectContainer(e.target.loader).parent;
while(boulderOfThisImage.numChildren){
boulderOfThisImage.removeChildAt(0);
}
boulderOfThisImage.addChild(e.target);
我强烈反对使用removeChildAt函数.更改显示列表结构后，可能会导致许多问题.但这行得通.
I highly disapprove using removeChildAt function. It may cause many problems after changing your display list structure. But it works.
