flex Container 类的getChildren方法只能得到调用对象的子对象
例如flex结构
<mx:VBox id="uploadbox">
<mx:HBox id="file1" paddingTop="10">
<mx:ProgressBar id="bar1" visible="true"
labelPlacement="center"
minimum="0" maximum="100"
label="当前进度: 0%"
direction="right"
mode="manual" width="308" height="27" />
<mx:Button label="上传" height="27" click="upload(event);" x="320" y="10"/>
</mx:HBox>
...... // 此处省略若干HBox
</mx:VBox>
代码程序
var hboxChild:Array = uploadbox.getChildren();
for(var i:int=0;i<hboxChild.length;i++)
{
trace("hboxChild.name= "+(hboxChild[i] as DisplayObject).name);
}
结果如下
hboxChild.name= file1 //如果没有设置name属性，则name = id
hboxChild.name= hb_5
hboxChild.name= hb_6
hboxChild.name= hb_7
hboxChild.name= hb_8
hboxChild.name= hb_9
