javascript - 如何在一天后调用Javascript倒计时并将一周添加到计时器中

Question

所以我有一个倒计时，我只想在它结束时显示一条消息（它实际上已经这样做了）并等待 1 天，然后再次开始倒计时并添加一周。

那是代码：

var countDownDate = new Date("Oct 17, 2018 20:00:00").getTime();

var x = setInterval(function() {

var now = new Date().getTime();

var distance = countDownDate - now;

var days = Math.floor(distance / (1000 * 60 * 60 * 24));
var hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
var seconds = Math.floor((distance % (1000 * 60)) / 1000);

if (days<1)
{
    document.getElementById("demo").innerHTML = hours + " Hours " + minutes + " Minutes " + seconds + " Seconds ";
    if(hours<1)
    {
        document.getElementById("demo").innerHTML = minutes + " Minutes " + seconds + " Seconds ";
    }
    if(minutes<1)
    {
        document.getElementById("demo").innerHTML = seconds + " Seconds ";}
    }
else {
    document.getElementById("demo").innerHTML = days + " Days " + hours + " Hours "
    + minutes + " Minutes " + seconds + " Seconds ";
    }

if (distance < 0) {
    clearInterval(x);
    document.getElementById("demo").innerHTML = "Rewards are given!";
}
}, 1000);
