急求一个150秒和180秒的FLASH倒计时器~~

我给你写个as2.0的吧。
你把你的铃声放到flash的库里，改名字为alarm,右键点击alarm,链接名字也为alarm.
然后把代码放到第一帧
clearInterval(intevaalId);
var total:Number = 180;
var bgalrm:Boolean;
var alarm:Sound = new Sound();
alarm.attachSound("alarm");
var shijiantxt = this.createTextField("shijiantxt", 10, 0, 0, 200, 30);
shijiantxt.text = total;
function jishi() {
shijiantxt.text = --total;
if (total<=20 && !bgalrm) {
bgalrm = true;
alarm.start(0, 1);
}
if (total<=0) {
clearInterval(intevaalId);
shijiantxt.text = "";
}
}
var intevaalId = setInterval(jishi, 1000);

你留下邮箱号，我给你发过去。是要*swf格式还是*exe格式？我都给你。面板如下图：（样式还可以修改）。

150秒的倒计时。

as3代码给你，自己改吧

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

var time:int = 150;
var i:int = time;
var tTimer:Timer = new Timer(1000);
a_btn.visible = false;
t_lab.visible=false;
function onTimer(e:TimerEvent):void
{
 
 time_txt.text = i.toString();
 if (i==0)
 {
  tTimer.stop();
  lable.visible = false;
  a_btn.visible = true;
  t_lab.visible=true;
  time_txt.visible=false;
  
 }
 i--;
}
tTimer.addEventListener(TimerEvent.TIMER,onTimer);
tTimer.start();
a_btn.addEventListener(MouseEvent.MOUSE_DOWN,ondown);
function ondown(e:MouseEvent):void
{
 tTimer.start();
 a_btn.visible = false;
 lable.visible = true;
 t_lab.visible=false;
 time_txt.visible=true;
 time_txt.text="";
 i=time;
}
