[jQuery] URL redirect

Hi,
I have an input text field with city names which uses the jquery
autocomplete plugin.
Now I would like to redirect the page when a city is selected. Can you
anybody tell me how I could go about doing it.
$().ready(function() {
$('#cities').autocomplete(".autocomplete.php", {
     width: 260,
        selectFirst: false,
        matchSubset :0,
});
});
