jquery - js cookie.js 如何在几分钟而不是几天内使cookie过期？

Question

我正在使用名为 jscookie.js 的 jquery cookie我已经阅读了自述文件，甚至将其实现到我的项目中。

自述文件解释了如何在“天”内使 Cookie 过期，而不是在几小时或几分钟内。

Create a cookie that expires 7 days from now, valid across the entire site:

Cookies.set('name', 'value', { expires: 7 });

如何将 Cookie 设置为在几分钟或几小时内过期？

JavaScript Cookie supports a Date instance to be passed in the expires attribute. That provides a lot of flexibility since a Date instance can specify any moment in time.

Take for example, when you want the cookie to expire 15 minutes from now:

var inFifteenMinutes = new Date(new Date().getTime() + 15 * 60 * 1000);
Cookies.set('foo', 'bar', {
    expires: inFifteenMinutes
});

Also, you can specify fractions to expire in half a day (12 hours):

Cookies.set('foo', 'bar', {
    expires: 0.5
});

Or in 30 minutes:

Cookies.set('foo', 'bar', {
    expires: 1/48
});
