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?

Would this work instead?

var date = new Date();
var midnight = new Date(date.getFullYear(), date.getMonth(), date.getDate(), 23, 59, 59);
$.cookie("ultOS", (i), {expires: midnight});

Answer 1

I think this would work:

var currentDate = new Date();
expirationDate = new Date(currentDate.getFullYear(), currentDate.getMonth(), currentDate.getDate()+1, 0, 0, 0);
$.cookie("ultOS", "5", {expires: expirationDate});
