Question

我的计时器有问题。我想要它做的是当倒计时达到“0天0小时0分0秒”时我希望它在0处停止而不显示像“-1天18小时12分57秒”这样的傻瓜”。有没有人有这样的经历？

我想我的“if”语句有问题可以停止倒计时。这是代码的样子：

<script>
    function getTimeRemaining(endtime) {
        var t = Date.parse(endtime) - Date.parse(new Date());
        var seconds = Math.floor((t / 1000) % 60);
        var minutes = Math.floor((t / 1000 / 60) % 60);
        var hours = Math.floor((t / (1000 * 60 * 60)) % 24);
        var days = Math.floor(t / (1000 * 60 * 60 * 24));
        return {
            'total': t,
            'days': days,
            'hours': hours,
            'minutes': minutes,
            'seconds': seconds
        };
    }

    function initializeClock(id, endtime) {
        var clock = document.getElementById(id);
        var daysSpan = clock.querySelector('.days');
        var hoursSpan = clock.querySelector('.hours');
        var minutesSpan = clock.querySelector('.minutes');
        var secondsSpan = clock.querySelector('.seconds');

        function updateClock() {
            var t = getTimeRemaining(endtime);

            daysSpan.innerHTML = t.days;
            hoursSpan.innerHTML = ('0' + t.hours).slice(-2);
            minutesSpan.innerHTML = ('0' + t.minutes).slice(-2);
            secondsSpan.innerHTML = ('0' + t.seconds).slice(-2);

            if (t.total <= 0) {
                clearInterval(timeinterval);
            }
        }

        updateClock();
        var timeinterval = setInterval(updateClock, 1000);
    }

    var deadline = 'December 16 2015 13:00:00 UTC-0800';
    initializeClock('clockdiv', deadline);
</script>

我会这样试试：

 var timeinterval;

 function updateClock() {
        var t = getTimeRemaining(endtime);

        if (t.total <= 0) {
            clearInterval(timeinterval);
        }else{
            daysSpan.innerHTML = t.days;
            hoursSpan.innerHTML = ('0' + t.hours).slice(-2);
            minutesSpan.innerHTML = ('0' + t.minutes).slice(-2);
            secondsSpan.innerHTML = ('0' + t.seconds).slice(-2);
        }

    }
    updateClock();  
    timeinterval = setInterval(updateClock, 1000);
