Set a cookie expire after 2 hours

Question

I have this JavaScript code:

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?

Answer 1

If you want to use the same type of function, transform the days param into hours and pass 2 to get a 2 hour expiration date.

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=/";
}

Well -most obvious thing is to make "expire" date +2 hours ? :). Here You have nice prototype for that: Adding hours to Javascript Date object?
