With regards to the most voted answer, I think there is a much simpler syntax by just appending the extra request value into the source url.

This:

$("#city_id").autocomplete({
    source: src+"?country_id="+$("#country_id").val().
    min_length: 3,
    delay: 300
});

does the same as:

$("#city_id").autocomplete({
    source: function(request, response) {
        $.ajax({
            url: src,
            dataType: "json",
            data: {
                term : request.term,
                country_id : $("#country_id").val()
            },
            success: function(data) {
                response(data);
            }
        });
    },
    min_length: 3,
    delay: 300
});

given that src is an url string.
