Question

as3是怎么实现遍历物件的？

在AS2中有如下代码：for(i in _root){trace(_root[i]);}在AS3中要怎么写？

Answer 1

disObj 是容器
for (var i:int = 0; i < disObj.numChildren; i++ ) {
if (disObj.getChildAt(i)) {
}
}

Answer 2

//将场景转换为MovieClip
var main:MovieClip=root as MovieClip;
for (var i:uint;i<main.numChildren;i++) {
trace(main.getChildAt(i));
}

Answer 3

for(var i in _root){
trace(_root[i]);
}
