今天看到一個容易理解的as3.0自訂事件執行個體：

package {import flash.display.Sprite;import flash.events.MouseEvent;import flash.events.EventDispatcher;public class myClip extends Sprite {public function myClip() {addEventListener(MouseEvent.CLICK,clickHander);}private function clickHander(evt:MouseEvent):void {var _clipEvent:clipEvent=new clipEvent();_clipEvent.M="wangyan";dispatchEvent(_clipEvent);}}}//庫綁定類package {import flash.events.Event;public class clipEvent extends Event {public static const CLIP_CLICK:String="clip_click";private var _mm:String;public function clipEvent() {super(CLIP_CLICK);}public function get M() {return _mm;}public function set M(a:String) {_mm=a;}}}//自訂事件類別function listen_clipEvent(evt:clipEvent) {trace("hello"+evt);}abc.addEventListener(clipEvent.CLIP_CLICK,listen_clipEvent);
