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

[Priest, James (NIH/NIEHS) [C]]

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
