JavaScript/jQuery 倒计时

Question

我想要完成的是实时更新的倒计时...像这样:

6 天(只是几天)

12 小时(1 天内的几个小时)

59 分钟(1 小时内仅几分钟)

59 秒(1 分钟内的几秒)

实现此目的的最佳方法？

您可以在 http://jsfiddle.net/gaby/QH6X8/79/ 找到一个工作示例

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);
