How can i get jquery countdown to redirect to a reset file

Question

here is my countdown

$('span.countdown').each(function() {
        var endtime = $(this).html();
        $(this).countdown({
            until:  endtime,
            format: 'dhmS',
            layout: '{d<}{dn} days {d>}{h<}{hn} hours {h>}{m<}{mn} mins {m>}{sn} secs',
            expiryUrl: self.location.href
        });
    });
}

i would like to redirect to index.php when countdown hits zero :)

Answer 1

Try changing it to expiryUrl: "something".

Answer 2

            expiryUrl: self.location.href
    to

            expiryUrl: window.location.href

or 

            expiryUrl: "absolute url" //ie http://domain/index.php
