flash倒计时怎么做？

我有as3.0的倒计时代码。

做一个动态文本,命名“chadate”

输入代码：

stage.addeventlistener(event.enter_frame,onevent);

functiononevent(evt:event):void{

vardate:date=newdate();

varfullyear:uint=date.fullyear;

varmonth:uint=date.month+1;

vardate2:uint=date.date;

varhours:uint=date.hours;

varminutes:uint=date.minutes;

varseconds:uint=date.seconds;

varday:uint=date.day;

vardate3:date=newdate(2009,1,18,0,0,0,0);

varshijiancha:number=(date3.gettime()-date.gettime())/1000;

if(shijiancha>0){

varshengyutian:uint=shijiancha/(3600*24);

varshengyuxiaoshi:uint=(shijiancha-shengyutian*3600*24)/3600;

varshengyufen:uint=(shijiancha-shengyutian*24*3600-shengyuxiaoshi*3600)/60;

varshengyumiao:uint=shijiancha-shengyutian*24*3600-shengyuxiaoshi*3600-shengyufen*60;

chadate.text="距哈尔滨大冬会开幕还有"+shengyutian+"天"+shengyuxiaoshi+"时"+shengyufen+"分"+shengyumiao+"秒";

}else{

chadate.text="倒计时已经结束，祝选手们取得好成绩。";

removeeventlistener(event.enter_frame,onevent);

}

}
