jQuery cookie到期值 [英] jQuery cookie expiration value
问题描述
我在这里阅读了许多jQuery Cookie问题，并且知道有一个jQuery Cookie插件（ jQuery cookie ）。没有多少调查，问题：有一种方法来确定cookie的过期日期？
I have read a lot of jQuery cookie questions on here and know there is a jQuery cookie plugin (jQuery cookie). Without doing much investigation, the question: is there a way to determine expiration date of cookie?
从jquery.cookie文档：
From the jquery.cookie doc:
/**
* Get the value of a cookie with the given name.
*
* @example $.cookie('the_cookie');
* @desc Get the value of a cookie.
*
* @param String name The name of the cookie.
* @return The value of the cookie.
* @type String
*
* @name $.cookie
* @cat Plugins/Cookie

看起来这个插件可以吗？
Doesn't seem that this plugin can do it?
我想这样做的原因是我的cookie在5分钟不活动后过期，Id想通知用户他们的会话即将从Javascript过期。
The reason I want to do this is that my cookie expires after 5 minutes of inactivity and Id like to notify user that their session is about to expire from Javascript.
推荐答案
除非有任何变化，否则您无法从设置它，但它是，当它过期它只是不会显示在cookie集合中不再....但你不能看到它在5分钟内过期。例如。
Unless something has changed, you can't get this value from a cookie, you can set it but that's it, when it expires it just won't show up in the cookie collection anymore....but you can't see that it expires in 5 minutes for example.
对于会话过期的最佳选择是使用 setTimeout（） 正确的延迟，例如如果是5分钟，您可能需要在4分30秒时发出警报，例如：
Your best bet for something along the lines of session expiration is to use setTimeout() with the correct delay, for example if it's 5 minutes, you may want to alert at 4 min 30 seconds, like this:
setTimeout(function() {
alert("Your session will expire in 30 seconds!");
}, 270000); //4.5 * 60 * 1000
