</ul>
<ul class='sortable'>

   <li>2</li>
   <li>3</li>

Ok, this alert two times when I sort with ULs. I need one time alert even sorted with UL or Li.

Answer 1

I have found a way to do it.

$updated = false;
$('.sortable').sortable(
{
    connectWith: '.sortable',
    stop: function()
    {
        if($updated)
        {
                alert('Updated!');
        }
        $updated = false;
    },
    update: function(e, ui)
    {
        $updated = true;
    }
});
