I am using jQuery UI draggable and sortable functions and I am new to this. I have list of items in left (generated from database ) and I have boxes on right where user can drag and drop them. While/after dropping user can sort them.

Problem: How can I get array of IDs of elements in each box after sorting?

I have tried .sortable("toArray") and sortable("serialize") but both return empty string.

Simple HTML

<div id="raspored">  
      <div class="left">
        <ul id="kanta">Delete</ul>    
        <ul id="lista_predmeta" class="droptrue">
          <li class="predmet ui-state-default" predmet-id="id_1">Item_1</li>
          <li class="predmet ui-state-default" predmet-id="id_2">Item_2</li>
          <li class="predmet ui-state-default" predmet-id="id_3">Item_3</li>
          <li class="predmet ui-state-default" predmet-id="id_4">Item_4</li>
        </ul>
      </div>
      <div class="right">     
        <ul class="raspored" razred="1">I</ul>  
        <ul class="raspored" razred="2">II</ul>  
        <ul class="raspored" razred="3">III</ul>  
        <ul class="raspored" razred="4">IV</ul>  
      </div>  
  </div> 

My jQuery functions

$(document).ready(function() {
     var url = "";
     var raz = 0;

    $( ".raspored" ).sortable({
        cursor: 'move',
        opacity: 0.65,
        stop: function ( event, ui){
            var data = $(this).sortable('toArray');
            console.log(data); // This should print array of IDs, but returns empty string/array
       }
    });

    $(".raspored").droppable({
         accept: ".predmet",   
         drop: function(event, ui){
            ui.draggable.removeClass("predmet");
            ui.draggable.addClass("cas");
            raz = $(this).attr("razred");
         }
    });


    $(".predmet").draggable({
        connectToSortable:".raspored",
        helper: "clone",
        revert: "invalid",

        stop: function(event, ui){
                var predmet = $(this).attr("predmet-id") ;
                console.log( "PredmetID = " + predmet + " | RazredID = " + raz);
        }
    });

    $("#kanta").droppable({
        accept: ".cas",
        drop: function(event, ui){
            ui.draggable.remove();
        }
    });

    $( ".raspored, .predmet, .cas, #kanta, #lista_predmeta" ).disableSelection();
  });

Sorted by: Reset to default 21

When you call toArray, you can pass an options object with an attribute field. This attribute field defines what attribute is used in the toArray call. For example:

var data = $(this).sortable('toArray', { attribute: 'predmet-id' });

That will give you an array of the predmet-id attributes of the items. See the toArray documentation.

Note that the default attribute is id, which is why your array returned empty strings before - none of your elements have id attributes!

use serialize that work for me. below are sample code that may help you.

<ul id="sortable">
<li id="ID_11" class="ui-state-default">sai</li>
<li id="ID_21" class="ui-state-default">2</li>
<li id="ID_3" class="ui-state-default">3</li>
<li id="ID_4" class="ui-state-default">4</li>
<li id="ID_5" class="ui-state-default">5</li>
<li id="ID_6" class="ui-state-default">6</li>
<li id="ID_7" class="ui-state-default">7</li>
<li id="ID_8" class="ui-state-default">8</li>
<li id="ID_9" class="ui-state-default">9</li>
<li id="ID_10" class="ui-state-default">10</li>
<li id="ID_11" class="ui-state-default">11</li>
<li id="ID_12"  class="ui-state-default">12</li>
</ul>
 <a href="javascript:void(0);" onClick="saveDisplayChanges();">Save</a>
 <span id="categorysavemessage"></span>

Javascript code are :

<script>
   $(function() {
   $( "#sortable" ).sortable();
});

function saveDisplayChanges()
{
  var order =  $("ul#sortable").sortable("serialize");
  var a = "hello";
  var b = "hi";
  $.post("update_displayorder.php?"+order+"&a=hello"+"&b=developer",{abc:a,xyz:b},function(theResponse){
  $("#categorysavemessage").html(theResponse);

});
}
</script>

Php script for fetch order data with other info update_displayorder.php script are :

<?php
echo "<pre>";
print_r($_REQUEST); 

$newOrder = $_POST['ID'];
$counter = 1;
foreach ($newOrder as $recordIDValue) {
   echo $counter .' '. $recordIDValue .'<br/>';
   $counter ++;
}
?>
