jQuery cookie持久化 [英] jQuery cookie persistence

问题描述

我使用此jquery插件成功地将Cookie添加到网站上的jQuery Ajax应用程序。

I am using this jquery plugin to successfully add cookies to a jQuery Ajax application on a website.

但是，我的很短的问题是，如何设置cookie无限期存在？

But, my very short question is, how can I set the cookie to exist indefinately?

我试图记住用户的偏好设置，将它们长期存储在包含每个用户唯一的数据数组的Cookie中。

I am trying to remember users preferences settings by storing them long term in a cookie containing an array of data unique to each user.

谢谢。

推荐答案

您无法将Cookie设置为无限期。

You can't set a cookie to exist indefinitely. You make a cookie persistent by setting an expiration date on it, and as the expiration date has to have a specific value, that's when the cookie will expire.

您可以设置一个过期日期，并且过期日期必须有一个特定的值。该cookie存活一年，例如：

You can make the cookie live for a year, for example:

$.cookie('the_cookie', 'the_value', { expires: 365 });

您也可以使用 Date 到期日期，但您应该保留日期在2038年的这一侧，因为一些系统不支持之后的日期。

You can also use a Date object for the expiration date, but you should keep the date on this side of year 2038, as some systems doesn't support dates after that yet.
