我遇到与倒计时插件有关的问题。 在文档中没有任何关于更改计数选项的信息。 问题是，它不能实时工作。在页面重新加载时，它从上一次开始计算。

这是与html标签的连接
$('section').ClassyCountdown({
end: $.now() + 645600 // end time});
这是JSFiddle https://jsfiddle.net/3nqs02q0/1/
倒计时JS代码从第6行开始。

正如PID已经指出的那样，配置参数需要是非易失性的，以便在页面刷新之间保持其值。
根据要求，这些值可以进行硬编码，存储在pom，localStorage，查询参数中，甚至可以存储为sessionStorage。
重要的是，cookie使用的是Unix，而不是Javascript时间。因此，配置值必须除以1000，如下面的代码所示。 OP也可能想同时使用＆＃34;现在＆＃34;和＆＃34;结束＆＃34;参数达到所需的时间间隔。
工作示例 - 运行代码段以尝试：
$('.countdown').ClassyCountdown({
theme: 'flat-colors',
now: Math.round( new Date( ).getTime() / 1000),
end: Math.round( new Date( '2017-01-01T00:00Z' ).getTime() / 1000),
onEndCallback: function() {
// do something ...
}

设定固定的结束时间。而不是：
$.now() + 645600
使用此构造函数：
(new Date(year, month, day, hours, minutes, seconds, milliseconds)).getTime()
例如，在2016年底结束时使用：
$('section').ClassyCountdown({
end: (new Date(2016, 11, 31, 23, 59, 59, 999)).getTime()
}); // ^^ month is 0-based
