public class Barbershop extends Sprite {
var customDF:Customer=new Customer("DFdou");
var waiter:Waiter=new Waiter("路人A");
public function Barbershop () {
addChild (waiter);
btnCutHair.addEventListener (MouseEvent.CLICK,cutHair);
btnSpecial.addEventListener (MouseEvent.CLICK,special);
}
function cutHair (_evt:MouseEvent) {
customDF.addEventListener (ServerEvent.CUT_HAIR,waiter.serve);
customDF.callServe (ServerEvent.CUT_HAIR,"MM1");
customDF.removeEventListener (ServerEvent.CUT_HAIR,waiter.serve);
}
function special (_evt:MouseEvent) {
customDF.addEventListener (ServerEvent.SPECIAL,waiter.serve);
customDF.callServe (ServerEvent.SPECIAL,"MM2");
customDF.removeEventListener (ServerEvent.SPECIAL,waiter.serve);
}
public function showInfo (_str:String) {
txtInfo.appendText (_str+"\n");
}
}
}
[/js]
自定义事件类ServerEvent.as：
[js]
package {
import flash.events.Event;
public class ServerEvent extends Event{
public static const CUT_HAIR:String="cut_hair";
public static const SPECIAL:String="special";
public var _server:String;//指定个变量来存放服务人员
public function ServerEvent (eventType:String):void {
super(eventType);
}
}
}
[/js]
Customer顾客类Customer.as：
[js]
package {
import flash.events.EventDispatcher;
public class Customer extends EventDispatcher {
public var _name:String;
public function Customer (name:String):void {
_name=name;
}
public function callServe(eventType:String,server:String){
var serverEvent:ServerEvent=new ServerEvent(eventType);
serverEvent._server=server;//指定服务的人
dispatchEvent(serverEvent);//发送事件
}
}
}
[/js]
Waiter类Waiter.as：
[js]
package {
import flash.display.Sprite;
public class Waiter extends Sprite{
public var _name:String;
public function Waiter (name:String) {
_name=name;
}
public function serve (_evt:ServerEvent) {
//调用root里的函数，这里是用来做Demo用到～
Object(root).showInfo("你需要"+_evt._server+"服务,服务类型为:"+_evt.type);
}
}
}
[/js]
自定义事件的具体流程：
1.自定义好事件类；
2.注册事件侦听器；例子中为Custom callServe
3.发送dispatch事件；
4.侦听事件，处理；例子中为Waiter serve
5.移除侦听。
