推荐答案

你有几个选择。例如，即使刷新，cookie也可用于在页面（或同一页面）之间存储数据。您只需要存储计时器的开始时间。您可以计算从当前时间减去开始时间之间的时间。因此它将具有正确的倒计时值，即使用户浏览到另一个站点并在一段时间之后返回。

祝你好运！

You have several options. For example cookies can be used to store data between pages (or same page) even when refreshed. You only need to store the start time of the timer. You can calculate the time between from the current time minus the start time. So it will have the correct countdown value, even if a user browses to another site and comes back some time later.
