Flash无法将radiobutton标签与字符串进行比较

为什么第一个跟踪打印的不是第二个跟踪，而我在属性面板中将标签设置为“hello”

它对我有用。。。至少使用此代码：

<?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">
<fx:Script>
    <![CDATA[
        protected function radiobutton1_clickHandler(event:MouseEvent):void{
            trace(event.target.label.toString());
            if (event.target.label.toString() == "hello") {
                trace("comparison works");         
            };  
        }
    ]]>
</fx:Script>
<s:RadioButton label="hello" click="radiobutton1_clickHandler(event)"/>
</s:Application>

错误肯定在其他地方

就我个人而言，我猜标签中意外出现了额外的空间

尝试跟踪（event.target.label.toString（）.length）如果不是5，那就是你的问题。

哦，是的，我在什么地方弄乱了大写字母。

<?xml version="1.0" encoding="utf-8"?>

           xmlns:s="library://ns.adobe.com/flex/spark" 
           xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">

    <![CDATA[
        protected function radiobutton1_clickHandler(event:MouseEvent):void{
            trace(event.target.label.toString());
            if (event.target.label.toString() == "hello") {
                trace("comparison works");         
            };  
        }
    ]]>
</fx:Script>
<s:RadioButton label="hello" click="radiobutton1_clickHandler(event)"/>
</s:Application>
