Flex中获取RadioButtonGroup中的RadioButton的值

Flex中获取RadioButtonGroup中的RadioButton的值

1、设计源码

<?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"
			   width="100%" height="100%">
	<s:layout>
		<s:BasicLayout/>
	</s:layout>
	
	<fx:Declarations>
		<s:RadioButtonGroup id="radiogroup"/>
	</fx:Declarations>
	
	<fx:Script>
		<![CDATA[
			import mx.controls.Alert;
			
			/*获取Radio中的值函数*/
			protected function clickHandler(event:MouseEvent):void
			{
				//获取radioButton的label值
				var radio:String = radiogroup.selectedValue.toString();
				//打印radioButton的label值
				Alert.show("选择："+radio);
			}

		]]>
	</fx:Script>
	
	<mx:VBox width="100%" horizontalAlign="center">
		<mx:HBox width="100%" horizontalAlign="center" paddingTop="100">
			<s:RadioButton label="篮球" groupName="radiogroup" selected="true"/>
			<s:RadioButton label="足球" groupName="radiogroup"/>
			<s:RadioButton label="排球" groupName="radiogroup"/>
		</mx:HBox>
		<s:Label height="10"/>
		<s:Button label="获取Radio值" click="clickHandler(event)" cornerRadius="8"/>
	</mx:VBox>
	
</s:Application>

2、设计结果

（1）初始化时

（2）选择“足球”时

（3）选择“排球”时
