Set a cookie expire after 2 hours
提问by Tureac Cosmin
I have this JavaScript code:
我有这个 JavaScript 代码：
function spu_createCookie(name, value, days) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = "; expires="+date.toGMTString();
}
else
var expires = "";
document.cookie = name+"="+value+expires+"; path=/";
}
How can I make the cookie expire after 2 hours?
如何让 cookie 在 2 小时后过期？
回答by Sébastien
If you want to use the same type of function, transform the daysparam into hoursand pass 2to get a 2 hour expiration date.
如果要使用相同类型的函数，请将daysparam 转换为hours并传递2以获得 2 小时的到期日期。
function spu_createCookie(name, value, hours)
{
if (hours)
{
var date = new Date();
date.setTime(date.getTime()+(hours*60*60*1000));
var expires = "; expires="+date.toGMTString();
}
else
{
var expires = "";
}
document.cookie = name+"="+value+expires+"; path=/";
}

Try this:
试试这个：
function writeCookie (key, value, hours) {
var date = new Date();
// Get milliseconds at current time plus number of hours*60 minutes*60 seconds* 1000 milliseconds
date.setTime(+ date + (hours * 3600000)); //60 * 60 * 1000
window.document.cookie = key + "=" + value + "; expires=" + date.toGMTString() + "; path=/";
return value;
};
Usage:
用法：
<script>
writeCookie ("myCookie", "12345", 24);
</script>
//for 24 hours

Well -most obvious thing is to make "expire" date +2 hours ? :). Here You have nice prototype for that: Adding hours to Javascript Date object?
嗯 - 最明显的事情是让“过期”日期 +2 小时？:)。在这里，您有很好的原型： 向 Javascript 日期对象添加小时数？

Try jquery-cookie. Makes it very easy to work with cookies.
试试jquery-cookie。使使用 cookie 变得非常容易。

This would do it.
这样就可以了。
var now = new Date();
var time = now.getTime();
time += 7200 * 1000;
now.setTime(time);
document.cookie =
name+ '=' + value +
'; expires=' + now.toGMTString() +
'; path=/';
