jQuery cookie expiry time
提问by Ganga
I was able to set a cookie using jQuery with a redirect to a landing page but I have no idea how can I set the cookie expiry date to less then one day (for example 15 minutes). I was not able to find explanation in the plugin documentation
我能够使用 jQuery 设置 cookie 并重定向到登录页面，但我不知道如何将 cookie 到期日期设置为不到一天（例如 15 分钟）。我无法在插件文档中找到解释
Here is my code:
这是我的代码：
$(function() {
var COOKIE_NAME = 'splash-page-cookie';
$go = $.cookie(COOKIE_NAME);
if ($go == null) {
$.cookie(COOKIE_NAME, 'test', { path: '/', expires: 1 });
window.location = "/example"
}
else {
// do nothing
}
});
Thank you for all help !
谢谢大家的帮助！
EDIT:I was able to set cookie as session cookie by skipping expire, well im fine with that but its not perfect, if you guys have some idea i would be grateful.
编辑：我能够通过跳过过期将 cookie 设置为会话 cookie，我对此很好，但它并不完美，如果你们有一些想法，我将不胜感激。

The plugins expiresoption accepts either a number or a date object.
pluginsexpires选项接受数字或日期对象。
If a number is passed, it's the number of days until the cookie expires, but if a date object is passed, it's the time and date when the cookie expires, so you can do
如果传递了一个数字，则它是距离 cookie 过期的天数，但如果传递了一个日期对象，则它是 cookie 过期的时间和日期，因此您可以这样做
var expDate = new Date();
expDate.setTime(expDate.getTime() + (15 * 60 * 1000)); // add 15 minutes
$.cookie(COOKIE_NAME, 'test', { path: '/', expires: expDate });

A fraction of a day should work, so for example there are 1440 minutes in a day so if you wanted the cookie to expire in 15 minutes you could simply divide the minutes by 1440 like so:
一天的一小部分应该可以工作，例如，一天有 1440 分钟，所以如果您希望 cookie 在 15 分钟后过期，您可以简单地将分钟除以 1440，如下所示：
$.cookie('foo', 'bar', {expires: 15/1440});
This would also work with hours, so for example if you wanted the cookie to expire in 2 hours you could do:
这也适用于数小时，因此例如，如果您希望 cookie 在 2 小时内过期，您可以执行以下操作：
$.cookie('foo', 'bar', {expires: 2/24});
A third option is to pass a date object like so:
第三种选择是传递一个日期对象，如下所示：
var expire = new Date();
//set expiry to current time plus 15 minutes in milliseconds
expire.setTime(expire.getTime() + (15 * 60 * 1000));
$.cookie('foo', 'bar', {expires: expire});
Hope this helps!
希望这可以帮助！
