Flex基礎知識點。 MenuBar labelField=@property。 使用@獲取屬性值。 <mx:Script>
????<![CDATA[
??????import mx.controls.Alert;
??????import mx.events.MenuEvent;
??????public function menuHandle(event:MenuEvent):void
??????{
????????Alert.show(event.item.@label);
??????}
????]]>
??</mx:Script>
????
??<mx:MenuBar id="mb" fontSize="12" labelField="@label" x="429" y="94" itemClick="menuHandle(event)">
????<mx:XMLList id="dataList" xmlns="">
????????
??????<meunitem label="JAVA">
????????<menuitem label="JDBC" />
????????
??????</meunitem>
????????
??????<meunitem label=".NET">
????????<menuitem label="WINFORM" />
??????</meunitem>
????????
??????<meunitem label="設計">
????????<menuitem label="photoshop" />
??????</meunitem>
????????
????</mx:XMLList>
??</mx:MenuBar> 對于菜單（MenuBar），統(tǒng)一推薦使用itemClick作為事件進行觸發(fā)。 通過event.item.@標簽名稱 的方式來獲得用戶所選擇的值 使用{變量名}可以拿到該組件對象。 <?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="initCollection()">
