javascript 倒数计时器删除时分秒.. 到期后

Question

我是 javascript 的新手，我不知道如何删除倒计时的过期部分。例如，当倒计时结束天数时，它会删除天数，然后它会删除小时数等，直到到达点 "Expired"

这里是JS代码：

var items = document.querySelectorAll('#clock');
for (var i = 0, len = items.length; i < len; i++) {
    (function () {
        var e = new Date("2018-12-31").getTime(),
            t = this.querySelector("[data-js=countdown]"),
            n = this.querySelector("[data-js=countdown-endtext]"),
            day = this.querySelector("[data-js=countdown-day]"),
            hour = this.querySelector("[data-js=countdown-hour]"),
            min = this.querySelector("[data-js=countdown-minute]"),
            sec = this.querySelector("[data-js=countdown-second]"),
            s = this.gjs_countdown_interval;
        s && s && clearInterval(s);
        var l = function (e, t, n, s) {
                day.innerHTML = e < 10 ? "0" + e : e,
                    hour.innerHTML = t < 10 ? "0" + t : t,
                    min.innerHTML = n < 10 ? "0" + n : n,
                    sec.innerHTML = s < 10 ? "0" + s : s
            },
            u = function () {
                var day = (new Date).getTime(),
                    hour = e - day,
                    min = Math.floor(hour / 864e5),
                    sec = Math.floor(hour % 864e5 / 36e5),
                    s = Math.floor(hour % 36e4 / 6e4),
                    u = Math.floor(hour % 6e4 / 1e3);
                l(min, sec, s, u), hour < 0 && (clearInterval(c),
                    n.innerHTML = "EXPIRED",
                    t.style.display = "none",
                    n.style.display = "")
            };
        if (e) {
            var c = setInterval(u, 1e3);
            this.gjs_countdown_interval = c,
                n.style.display = "none",
                t.style.display = "", u()
        } else l(0, 0, 0, 0)
    }.bind(items[i]))();
}

HTML:

<section class="flex-sect">
    <div id="clock" class="countdown">
        <span data-js="countdown" class="countdown-cont">
        <div class="countdown-block">
            <div data-js="countdown-day" class="countdown-digit"></div>
            <div class="countdown-label">days</div>
        </div>
        <div class="countdown-block">
            <div data-js="countdown-hour" class="countdown-digit"></div>
            <div class="countdown-label">hours</div>
        </div>
        <div class="countdown-block">
            <div data-js="countdown-minute" class="countdown-digit"></div>
            <div class="countdown-label">minutes</div>
        </div>
        <div class="countdown-block">
            <div data-js="countdown-second" class="countdown-digit"></div>
            <div class="countdown-label">seconds</div>
        </div>
        </span>
        <span data-js="countdown-endtext" class="countdown-endtext"></span>
    </div>
</section>

非常感谢你们的帮助

您可以检查某个时间段是否为 0，并且所有较大的时间段是否也为 0。

if (day == 0) {
    day.innerHTML = "";
}
if (day == 0 && hour == 0) {
    hour.innerHTML = "";
}
if (day == 0 && hour == 0 && min == 0) {
    min.innerHTML = "";
}
if (day == 0 && hour == 0 && min == 0 && sec == 0) {
    sec.innerHTML = "";
    n.innerHTML = "Expired";
}

我终于能够修复我的错误，我是这样做的：而不是 {{ request.GET.date }} GMT-7 提供您的参数并且效果很好！

<script>
    var deadline = new Date("{{ request.GET.date }} GMT-7").getTime();

    var x = setInterval(function () {

        var now = new Date().getTime();
        var t = deadline - now;
        var days = Math.floor(t / (1000 * 60 * 60 * 24));
        var hours = Math.floor((t % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
        var minutes = Math.floor((t % (1000 * 60 * 60)) / (1000 * 60));
        var seconds = Math.floor((t % (1000 * 60)) / 1000);

        if (days == 0) {
            document.getElementById("day").innerHTML = '';
            document.getElementById("day-title").innerHTML = '';
        } else if (days ==1) {
            document.getElementById("day-title").innerHTML = 'Day';
            document.getElementById("day").innerHTML = days;
        } else {
            document.getElementById("day").innerHTML = days;
            document.getElementById("day-title").innerHTML = 'Days';
        }
        if (hours != 0) {
            document.getElementById("hour").innerHTML = hours;
        } else {
            document.getElementById("hour").innerHTML = '';
            document.getElementById("hour-title").innerHTML = '';
        }

        document.getElementById("minute").innerHTML = minutes;
        document.getElementById("second").innerHTML = seconds;
        if (t < 0) {
            clearInterval(x);
            document.getElementById("clock").innerHTML = '';
        }
    }, 1000);
</script>
