[TABS] Is there any way to pass variable to the server using tabs?

[TABS] Is there any way to pass variable to the server using tabs?

I figured it out (calendar-date-container contains the Unix timestamp
of that day at midnight):
$(".calendar-date-container").click(function() {
var url = 'day.php?t=' + this.id;
$('#tabs').tabs('url', 2, url);
$('#tabs').tabs('select', 2);
return false;
});
