[jQuery] autocomplete help - make another ajax call when results picked?

[jQuery] autocomplete help - make another ajax call when results picked?


I'm using Jorn's Autocomplete plugin and am successfully using it to
return a list of users along with a user_ID. What I'd like to do now is
when the user selects a person from the autocomplete list - via Ajax
take that user_ID, populate a table in my database and return another
value .
Right now I have:
$("#personIDdisplay").result(function(event, data, formatted) {
    if (data)
        $('#personID').val(data[1]);
});
This populates a hidden field (personID) with the value returned via
autocomplete.
What I'd like to do is instead that that value (data[1]) and use it to
make another Ajax call to run a query and then return another value -
but now sure exactly how to do that? :)
Is it just a matter of sticking in a ajax call and doing something like
this??
(psuedo code)
$("#personIDdisplay").result(function(event, data, formatted) {
    if (data)
    $.ajax({
     url: "dosomething.cfm",
    data: "id = .val(data[1]) ",
     success: function (data) {
         $('#personID').val(data);
     }
    });
I'm off to tinker but any feedback would be appreciated!
Thanks,
Jim
