jQuery autocomplete on multiple fields

Surprisingly, I didn't find any answers to my question.

I want to make a form on jQuery with two fields.

1. City Code.
2. City Name.

and when I enter a city code and go out of the field. I want an autocomplete on the city name.

I Installed the jQuery Autocomplete plugin.

and I have the following code :

$(document).ready(function() {
    $("#field_localite").autocomplete('admin/ajax/npa', {
       extraParams: {
           npa: function() { return $("#field_npa").val(); }
       }
    });

    $("#field_npa").blur(function() {
        $("#field_localite").search();
    });
});

The problem is that the .search() method. doesnt launch the autocomplete.

I'm looking for a method to trigger this autocomplete search on the field.

do you know a way or a plugin able to do this search ?

thanks in advance

BTW : the PHP code behin is totally tested and works, it returns the data when doing the call.

$("#field_localite").autocomplete("search"); should do the trick.

got it.

finally I did it another way.

I put the autocomplete on the city code field :

$("#field_npa").autocomplete(Drupal.settings.basePath+'admin/ajax/npa', {
   formatItem: formatItem,
   cacheLength: 1,
   minChars:4

}).result(function(event, data, formatted) {
    $("#field_localite").val(data[1]);
});

function formatItem(row) {
        return row[0] + " " + row[1];
}

and this did the trick as I wanted.
