JS 倒计时实现代码(时、分，秒)

Posted 2023-03-29

参考技术A JS实现倒计时(时、分，秒)
var
interval
=
1000;
function
ShowCountDown(year,month,day,divname)

var
now
=
new
Date();
var
endDate
=
new
Date(year,
month-1,
day);
var
leftTime=endDate.getTime()-now.getTime();
var
leftsecond
=
parseInt(leftTime/1000);
//var
day1=parseInt(leftsecond/(24*60*60*6));
var
day1=Math.floor(leftsecond/(60*60*24));
var
hour=Math.floor((leftsecond-day1*24*60*60)/3600);
var
minute=Math.floor((leftsecond-day1*24*60*60-hour*3600)/60);
var
second=Math.floor(leftsecond-day1*24*60*60-hour*3600-minute*60);
var
cc
=
document.getElementById(divname);
cc.innerhtml
=
"脚本之家提示距离"+year+"年"+month+"月"+day+"日还有："+day1+"天"+hour+"小时"+minute+"分"+second+"秒";

window.setInterval(function()ShowCountDown(2010,4,20,'divdown1');,
interval);
