How to expire a Cookie using Jquery at midnight?

Question

I did this:

$.cookie(\"ultOS\", (i), {expires:1});

But it will only expire next day.

How can I expire a cookie at midnight?

Answer 1

According to the latest version of ths cookie plugin (assuming this is the one you're using: http://plugins.jquery.com/project/Cookie), you can pass a normal Date object in.

I haven't tried it, but the source of the plugin is fairly straightforward....

if (options.expires && (typeof options.expires == 'number' || options.expires.toUTCString)) {
            var date;
            if (typeof options.expires == 'number') {
                date = new Date();
                date.setTime(date.getTime() + (options.expires * 24 * 60 * 60 * 1000));
            } else {
                date = options.expires;
            }
            expires = '; expires=' + date.toUTCString(); // use expires attribute, max-age is not supported by IE
        }

If you pass in a number, it assumes that's number of days. If you pass in a Date, it takes that.
