动态创设button，动态指定事件

动态创建button，动态指定事件
ActionScript的很多写法与JavaScript的写法很像

var button:Button = new Button;button.label = "按钮";button.id = "button_1";button.addEventListener(MouseEvent.CLICK, clickHandler("hello"));或者如下//button.addEventListener(MouseEvent.CLICK, function(e:MouseEvent):void{clickChangeHandler(e, "hello")});

private function clickHandler(title:String):Function{return function(e:MouseEvent):void{clickChangeHandler.apply(null, [e, title])};}

private function clickChangeHandler(event:Event, title:String):void{Alert.show(title);}
