我需要在 jQuery 中修改倒计时

Question

我想修改我的 jQuery 代码请帮忙。这是倒数计时器，从 30 开始，到 0 结束，然后停止。

我想要倒计时从 0 开始，然后从 30 重新开始。我想要从 30 到 0 随机倒计时，然后从 30 开始到 0。

// Random Countdown Timer Script, by http://ctrtard.com

var timer;

function startCount() {
    timer = setInterval(count, 1000); // 200 = 200ms delay between counter changes. Lower num = faster, Bigger = slower.
}

function count() {
    var rand_no = Math.ceil(1 * Math.random()); // 9 = random decrement amount. Counter will decrease anywhere from 1 - 9.
    var el = document.getElementById('counter');
    var currentNumber = parseFloat(el.innerHTML);
    var newNumber = currentNumber - rand_no;
    if (newNumber > 0) {
        el.innerHTML = newNumber;
    } else {
        el.innerHTML = "Sold Out"; // This message is displayed when the counter reaches zero.
    }
}

function count() {
    var rand_no = Math.ceil(1 * Math.random()); // 9 = random decrement amount. Counter will decrease anywhere from 1 - 9.
    var el = document.getElementById('counter');
    var currentNumber = parseFloat(el.innerHTML);
    var newNumber = currentNumber - rand_no;
    if (newNumber > 0) {
        el.innerHTML = newNumber;
    } else {
        setElemVal(el , 30);
        count();   
    }
}

function setElemVal(el , val) {
    el.innerHTML = '';
    el.innerHTML = val;
}

只需添加另一个函数来重置值并更改 else 条件。
