jQuery UI Autocomplete with CI ??

[eluser]josebyte[/eluser]
The code works, thanks!!
I haven´t any idea of jquery but resolved the problem using function() before autocomplete:

Code:

$(function() {
    $( "#city" ).autocomplete({
            source: function(req, add){
                    $.ajax({
                        url: 'http://www.URL.com/index.php/ajax/search'+'/'+$('#provincia').val()
,
                        dataType: 'json',
                        type: 'POST',
                        data: req,
                        success: function(data){
                            if(data.response =='true'){
                               add(data.message);
                            }
                        }
                    });
            },
            minLength: 3,
            select: function(event, ui){
                $(this).end().val(ui.item.value);
            }
    });
});
