JavaScript / jQuery倒计时 [英] JavaScript / jQuery Countdown

问题描述

我想完成的是一个实时更新的倒数计时，如下所示：

What I'd like to accomplish is a countdown that updates live... like this:

6天（仅几天）

12小时（仅在1天之内的小时）

12 Hours (just hours within 1 day)

59分钟（仅1个小时之内的分钟）

59 Minutes (just minutes within 1 hour)

59秒（在1分钟内仅几秒钟）

59 Seconds (just seconds within 1 minute)

实现此目标的最佳方法？

Best way to accomplish this?

推荐答案

您可以在 http：// jsfiddle中找到有效的示例.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);
