在《第3号法》中,我利用复读部分建立了信库中的儿童部分。 我只想改变复读所创造的儿童部分。 是否有办法或途径接触特定的儿童部分,并作出必要的财产改变?
<mx:Repeater id="myrep" dataProvider="{myAC}">
<mx:Label id="Label1" text="This is button "/>
</mx:Repeater>
在上述法典中,我设立了10个标签,我想只对第5个拉贝尔作一些改动? 这是可能的。

是的,这是可能的。
你们可以接触重复产生的内容,例如:
component_id[index]
So in your case,for changing 5th element s label, your code would be Label1[4].text= blah blah
.
However changing repeater s generated components in this manner, is a bad practice. Instead use bindings.
例如:
//...
[Bindable]
var myAC:ArrayCollection = new ArrayCollection(["label1","label2","label3","label4","label5","label6"]) ;
//...
<mx:Repeater id="myrep" dataProvider="{myAC}">
<mx:Label id="Label1" text="{myrep.currentItem}"/>
</mx:Repeater>
//Changing label of 5th element
myAC[4] = blah blah ;
