body: <p>I've a question for you ... </p>
  
  <p>I've a function for autocomplete some text and on select i want return 2 value from the function ... this is my code:</p>
  
  <pre><code>function autoComp(field, srt, file, act) {
        $( field ).autocomplete({
              minLength: srt,
              source: function( request, response ) {
                    $.ajax({
                          url: file,
                          type: 'post',
                          dataType: "json",         
                          data: {'azione':act, 'txt':request.term},
                          success: function(data) {
                                response( $.map( data.result, function( item ) {
                                      return { 
                                            label: item.text, 
                                            value: item.text,
                                            id:  item.id
                                      }
                                }));
                          }
                    });
              },
              select: function( event, ui ) { 
                    var obj = {};
                    obj[0] = ui.item.id;
                    obj[1] = ui.item.label;
                    return obj;
              }
        }); 
  }
  
  $(document).on('focus', '.farmCompl', function(){
        obj = autoComp(this, 3, 'search.php', 'music');
        if(obj){
              alert(obj[0]);
              alert(obj[1]);
        }
  });
  </code></pre>
  
  <p>autoComp(...) wants to be a general function that is called from many places in my project ....
  'field' is the selector to be completed (ex. '#text1'), srt is the start of automplete ....
  Ajax works correctly in fact autocomplete presents the database options ...
  The problem is on the selection of the option .... 
  When I select the option, I want that autocomplete return the values ​​of id and label to the function or the event that called autoComp(...)
  I hope to have been clear
  Bye</p>
