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:

var sortableLinks = $("#category_links_list_3");
var linkOrderData = $(sortableLinks).sortable('serialize');

category_links_list_3 is the id of the UL

The DOM structure is:

<div class="hidden" id="inline_list_3">
    <ul class="category_links_list ui-sortable" id="category_links_list_3">
        <li class="link_title ui-state-default" id="category_link_8">Coconut Oil</li>
        <li class="link_title ui-state-default" id="category_link_9">Hempseed</li>
    </ul>
</div>

Thanks...

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();

  });

#sort_tickets
  %ul#sortable
    - @tickets.each do |ticket|
      %li.ui-state-default(data-item="#{ticket.id}")<
        %span.ui-icon.ui-icon-arrowthick-2-n-s<
        = ticket.customer

I finally got the answer! You need to make the UL sortable first before calling the serialize method on it:

var sortableLinks = $("#category_links_list_3");
$(sortableLinks).sortable();
var linkOrderData = $(sortableLinks).sortable('serialize');

This time linkOrderData contains category_link[]=8&category_link[]=9

If serialize returns an empty string, make sure the id attributes include an underscore. They must be in the form: "set_number" For example, a 3 element list with id attributes foo_1, foo_5, foo_2 will serialize to foo[]=1&foo[]=5&foo[]=2. You can use an underscore, equal sign or hyphen to separate the set and number. For example foo=1 or foo-1 or foo_1 all serialize to foo[]=1.

Above one is a example. that i used it. That is why I saw 2 you.
