JavaScript/jQuery倒计时

countdown javascript

dcolumbus · 技术社区 · 15 年前

我想完成的是倒计时,实时更新。。。这样地:

12小时(1天内只有几个小时)

59分钟(1小时内只有几分钟)

实现这一目标的最佳方法是什么?

你可以在 http://jsfiddle.net/gaby/QH6X8/79/

var end = new Date('15 Dec 2010');

var _second = 1000;
var _minute = _second * 60;
var _hour = _minute * 60;
var _day = _hour *24

var timer;

function showRemaining()
{
    var now = new Date();
    var distance = end - now;
    if (distance < 0 ) {
       // handle expiry here..
       clearInterval( timer ); // stop the timer from continuing ..
       alert('Expired'); // alert a message that the timer has expired..
    }
    var days = Math.floor(distance / _day);
    var hours = Math.floor( (distance % _day ) / _hour );
    var minutes = Math.floor( (distance % _hour) / _minute );
    var seconds = Math.floor( (distance % _minute) / _second );

    var countdownElement = document.getElementById('countdown');
    countdownElement.innerHTML = 'Days: ' + days + '<br />';
    countdownElement.innerHTML += 'Hours: ' + hours+ '<br />';
    countdownElement.innerHTML += 'Minutes: ' + minutes+ '<br />';
    countdownElement.innerHTML += 'Seconds: ' + seconds+ '<br />';
}

timer = setInterval(showRemaining, 1000);
