Jquery sortable('serialize')

Question

Is it possible to get the serialized list of items from a UL in jquery by calling the serialize method directly instead of using a callback? The code snippet:

This post was very helpful. In case you're looking for additional help, here's how I got it to work (using haml-rails). Using the toArray function is slightly different. If using `serialize' you would have to set the attribute, again, as 'data-item="data-item_#{id}'.

Thank you, Internet, for knowing so many programming solutions.

:css
  #sortable { list-style-type: none; margin: 40 20; padding: 0; width: 500; }
  #sortable li { margin: 0 3px 3px 3px; padding: 0.4em; padding-left: 1.5em; font-size: 1.4em; height: 18px; }
  #sortable li span { position: absolute; margin-left: -1.3em; }

:javascript
  $(function() {

    $( "#sortable" ).sortable({
      update: function( event, ui ) {
        var data = $("#sortable").sortable('toArray', {attribute: "data-item"});  
        // return ids in order after update
        //alert(JSON.stringify(data));
        $.ajax({
          type: "PATCH",
          async: true,
          url: "/calendar/update_order.json",
          data: JSON.stringify(data),
          dataType: 'json',
          contentType: 'application/json',
          error: function(data) { return false; },
          success: function(data) { return false; }
        });
      }
    });
    $( "#sortable" ).disableSelection();

  });
