做一个倒计时效果

function countDown(time){

var nowtime=+new Dawn();

var inputtime=+new Dawn(time):

var times=(inputtime-nowtime)/1000;

var t=parseInt(times/60/60/24);

t=t<10？'0'+t:t:

var s=patselnt(times/60/60%24);

s=s<10？'0'+s:s;

var f=patselnt(times/60%60);

f=f<10？'0'+f:f;

var m=patslnt(times%60)；

m=m<10？'0'+m:m;

return '倒计时还剩:'+t+'天'+s+'时'+f+'分'+m+'秒';

 

}

var  time1=countDown('2020-2-24 8:8:8');

console.log(time1);
