你需要的只是一个倒计时函数，方法有很多，例如：
倒计时函数：
/*** daysID : 显示天数容器id
* hoursID : 显示小时容器id
* minuteID : 显示分钟容器id
* secondID : 显示秒数容器id
* endTime ：结束时间，设置倒计时的时间
* **/
function getRTime(daysID,hoursID,minuteID,secondID,endTime){
var EndTime = new Date(endTime)
var NowTime = new Date()
var t = EndTime.getTime() - NowTime.getTime()
var d = Math.floor(t/1000/60/60/24)
var h = Math.floor(t/1000/60/60%24)
var m = Math.floor(t/1000/60%60)
var s = Math.floor(t/1000%60)
if(s < 0){
clearInterval(timer)
d = 0
h = 0
m = 0
s = 0
}
document.getElementById(daysID).innerHTML = d
document.getElementById(hoursID).innerHTML = h
document.getElementById(minuteID).innerHTML = m
document.getElementById(secondID).innerHTML = s
}
调用：
var timer = setInterval(getRTime('days','hours','minute',null,'2017/6/22 24:00:00'),1000)
