如何在特定时间自动重新加载网页？ [英] How to automatically reload a web page at a certain time?

问题描述

我有一个网站，我希望在特定时间重新加载，例如下午3:35，而不是像5分钟之后的特定时间间隔。我该怎么做？

I have a website that I want to be reloaded at a certain time, like 3:35pm, not after a specific interval like 5min. How do I do that?

推荐答案

以下JavaScript代码片段可以让您在给定时间刷新：

The following JavaScript snippet will allow you to refresh at a given time:

function refreshAt(hours, minutes, seconds) {
    var now = new Date();
    var then = new Date();

    if(now.getHours() > hours ||
       (now.getHours() == hours && now.getMinutes() > minutes) ||
        now.getHours() == hours && now.getMinutes() == minutes && now.getSeconds() >= seconds) {
        then.setDate(now.getDate() + 1);
    }
    then.setHours(hours);
    then.setMinutes(minutes);
    then.setSeconds(seconds);

    var timeout = (then.getTime() - now.getTime());
    setTimeout(function() { window.location.reload(true); }, timeout);
}

然后你可以添加一个脚本标签来调用 refreshAt（）函数。

Then you can add a script tag to call the refreshAt() function.

refreshAt(15,35,0); //Will refresh the page at 3:35pm
