Adobe FLEX学习笔记（7）- 给组件…

一、方便一点的

<mx:Application
   xmlns:mx="http://www.adobe.com/2006/mxml"
   layout="vertical">

   <mx:Button id="btn" label="Show Names"click="showNames(event)"/>

   <mx:Script>
       <![CDATA[

           private function showNames(evt:MouseEvent):void
           {
               var temp:Array = new Array("George","Tim","Alex","Dean");
               trace(temp.toString());
           }
       ]]>
   </mx:Script>

</mx:Application>

点击button，在控制台显示temp中的内容

二、另一种方式，通过as代码来完成添加

<mx:Application
   xmlns:mx="http://www.adobe.com/2006/mxml"
   layout="vertical"
   creationComplete="initApp(event);">

   <mx:Button id="btn" label="ShowNames"/>

   <mx:Script>
       <![CDATA[
           import mx.events.FlexEvent;

           private function initApp(evt:FlexEvent):void
           {
               btn.addEventListener(MouseEvent.CLICK,showNames);
               btn.addEventListener(MouseEvent.CLICK,showTitles);
           }

           private function showNames(evt:MouseEvent):void
           {
               var temp:Array = new Array("George","Tim","Alex","Dean");
               trace(temp.toString());
           }

           private function showTitles(evt:MouseEvent):void
           {
               var temp:Array = newArray("Director","Vice-President","President",
"CEO");
               trace(temp.toString());
           }

       ]]>
   </mx:Script>

</mx:Application>
在initApp方法中为button添加事件监听器，因为btn.addEventListener(MouseEvent.CLICK,showNames);
写在btn.addEventListener(MouseEvent.CLICK,showTitles)的前面，所以showNames方法先执行，如果想指定方法的执行顺序，可以这样修改initApp方法

private function initApp(evt:FlexEvent):void {
   btn.addEventListener(MouseEvent.CLICK,showNames,false,0);
   btn.addEventListener(MouseEvent.CLICK,showTitles,false,1);       
}

第四个参数值大的方法先执行，当然也可以把btn.addEventListener(MouseEvent.CLICK,showTitles)写在btn.addEventListener(MouseEvent.CLICK,showNames)前面。
