actionscript3.0自定义事件机制简单编程实例

话不多说，直接上源码，如下：

1.继承Event，DataEvent.as

package event{
import flash.events.Event;
public class DataEvent extends Event{
private var eventData:*;
private var eventData1:*;
public function DataEvent(type:String,bubbles:Boolean=false,cancelable:Boolean=false,data:*=false,data1:*=true){
super(type,bubbles,cancelable);
this.eventData = data;
this.eventData1 = data1;
}
public function get data():*{
return this.eventData;
}
public function get data1():*{
return this.eventData1;
}
public override function clone():Event{
return new DataEvent(type,bubbles,cancelable,eventData,eventData1);
}
public override function toString():String{
return formatToString("DataEvent","type","bubbles","cancelable","data","data1");
}
}
}

2.继承DataEvent，YYEvent.as

package event{
public class YYEvent extends DataEvent{
import flash.events.Event;
public static const Login:String = "login";
public function YYEvent(type:String,data:*=true,data1:*=true){
super(type,true,true,data,data1);
}
public override function clone():Event{
return new YYEvent(type,data,data1);
}
}
}

3.事件触发，MyEventResponse.as

package event{
import flash.events.EventDispatcher;
import event.YYEvent;
public class MyEventResponse{
private var myDispatcher:EventDispatcher = null;
public function MyEventResponse(){
this.myDispatcher = new EventDispatcher();
}
public function addEventListener(type:String,handler:Function):void{
this.myDispatcher.addEventListener(type,handler);
}
public function myEventDispatch():void{
var event:YYEvent = new YYEvent(YYEvent.Login);
this.myDispatcher.dispatchEvent(event);
}
}
}

4.在event.as中调用上面的三个as文件

package
{
import flash.display.Sprite;

import event.YYEvent;

import event.MyEventResponse;
public class events extends Sprite
{
private var myEventDispath:MyEventResponse = new MyEventResponse();
public function events()
{
login();
this.myEventDispath.myEventDispatch();
}

/*

 *写一个函数，名为onLogin，作为YYEvent.Login事件的响应，这里略去，不会写的朋友可以私下联系

 */


public function login():void{
this.myEventDispath.addEventListener(YYEvent.Login,onLogin);
}
}
}
