Flex 构建器层次结构输出中的 Action script3 跟踪

Question

我正在使用 Flex builder 4.5，我的问题是这个代码不起作用，当我使用 Trace(event.target) 时，我在控制台中得到以下结果，

deleteme.ApplicationSkin2._ApplicationSkin_Group1.contentGroup.VGroup5.button1

如果我替换“if”语句中的这一长行，代码就可以工作。 （deleteme是项目名称）。你不认为它应该只说button1而不是所有层次结构的长线，如果是这样的话我们如何缩短它？

<?xml version="1.0" encoding="utf-8"?>
 <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
           xmlns:s="library://ns.adobe.com/flex/spark" 
           xmlns:mx="library://ns.adobe.com/flex/mx" 
           minWidth="955" minHeight="600"
           initialize="handleClick(event)">
<fx:Declarations>
    <!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>

<fx:Script>
    <![CDATA[
        private function init():void{
            button2.addEventListener(MouseEvent.CLICK, handleClick);
        }
        private function handleClick(event:Event):void{
            trace(event.target);
            if(event.target == "button1"){
                button1.label = "Button 1 clicked";
            }else if(event.target == "button2"){
                button2.label = "Button 2 clicked";
            }
        }

    ]]>
</fx:Script>
<s:VGroup width="100%">
    <s:Button id="button1" label="Button 1" click="handleClick(event)"/>
    <s:Button id="button2" label="Button 2" />
</s:VGroup>
</s:Application>

预先感谢，

（我尝试使用 sdk 4.1 还是相同的答案）

请改用以下代码：

<?xml version="1.0" encoding="utf-8"?>
 <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
           xmlns:s="library://ns.adobe.com/flex/spark" 
           xmlns:mx="library://ns.adobe.com/flex/mx" 
           minWidth="955" minHeight="600"
           initialize="handleClick(event)">
<fx:Declarations>
    <!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>

<fx:Script>
    <![CDATA[
        private function init():void{
            button2.addEventListener(MouseEvent.CLICK, handleClick);
        }
        private function handleClick(event:Event):void{
            trace(event.target);
            if(event.currentTarget == button1){
                button1.label = "Button 1 clicked";
            }else if(event.currentTarget == button2){
                button2.label = "Button 2 clicked";
            }
        }

    ]]>
</fx:Script>
<s:VGroup width="100%">
    <s:Button id="button1" label="Button 1" click="handleClick(event)"/>
    <s:Button id="button2" label="Button 2" />
</s:VGroup>
</s:Application>

将视觉对象与字符串进行比较是没有意义的。将物体与物体本身进行比较。
