Question

Current Problem

---

In relearning jQuery/jQueryUI, I’m trying to call an event on an element after sorting it. This is probably relatively simple to do since jQuery has many ways to implement callbacks.

jQuery(document).ready(function($) {
  $('ul').addClass('list-unstyled');
  $('.sortable').sortable({
    revert: true,
    connectWith: ".sortable"
  });
});

ul {
  margin: .8rem 2rem !important;
}

li {
  margin: 0;
  padding: 0;
}

div>div {
  border: 1px solid #999;
  margin-bottom: 2px;
}

body {
  padding: 1rem;
}

.sortable {
  cursor: pointer;
}

.sortable>div:hover {
  background: #f0f0f0;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">

<div class="sortable">
  <div>
    <ul class="1">
      <li>test 1</li>
      <li>test 2</li>
    </ul>
  </div>
  <div>
    <ul class="2">
      <li>test 3</li>
      <li>test 4</li>
    </ul>
  </div>
</div>
<div class="sortable">
  <div>
    <ul class="3">
      <li>test 7</li>
      <li>test 8</li>
    </ul>
  </div>
  <div>
    <ul class="4">
      <li>test 9</li>
      <li>test 0</li>
    </ul>
  </div>
</div>

So let’s say I move the 3/4 list. I want to issue a callback (to change the background or the font size) after the element is finished moving.

Edit(s)

• 20101019-1145EST: I think I need to be more clear. I’m trying to call the event on a particular element that is sorted. I guess I might be able to use the sort/change function, but shouldn’t there be a conditional involved? This involves more than adding a class, the eventual function I plan to attach will perform some AJAX as well as some calculations.

Answer 1

Use the stop event of the sortable plugin.

This event is triggered when sorting
has stopped.

In your example

$('.sortable')
    .sortable({
       revert       : true,
       connectWith  : ".sortable",
       stop         : function(event,ui){ /* do whatever here */ }
    });
