长按事件和短按事件的实现 Flash as3.0

舞台上有一个动态文本框（txtTime）和一个按钮(btnOnClick)

?

import flash.events.MouseEvent;
import flash.utils.Timer;
import flash.events.TimerEvent;

var timeNum=1;??? //默认时间是01;
txtTime.text="0"+timeNum;

var timer:Timer;
var delay:Number=1000;
btnOnClick.addEventListener(MouseEvent.MOUSE_DOWN,onDown);
btnOnClick.addEventListener(MouseEvent.MOUSE_UP,onUp);
?
function onDown(e:MouseEvent):void
{
??? timer = new Timer(delay,1); //超过1秒就算是长按
??? timer.addEventListener(TimerEvent.TIMER,onTimer);
??? timer.start();
}

var tm:Timer = new Timer(100,0); function onTimer(e:TimerEvent):void {?? ?tm.start(); ?tm.addEventListener(TimerEvent.TIMER,timerListener); ??? timer.removeEventListener(TimerEvent.TIMER,onTimer); } function timerListener(e:TimerEvent):void { ?timeNum++; ?txtTime.text=timeNum;
