jQuery UI Sortable — How can I cancel the click event on an item that's dragged/sorted?

I have a jQuery UI Sortable list. The sortable items also have a click event attached. Is there a way to prevent the click event from firing after I drag an item?

$().ready( function () { 
 $('#my_sortable').sortable({
   update: function() { console.log('update') },
   delay: 30
 });    

 $('#my_sortable li').click(function () {    
   console.log('click');
 });                        

});
#my_sortable li {
          border: 1px solid black;
          display: block;
          width: 100px;
          height: 100px;    
          background-color: gray;
        }
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.1/jquery-ui.min.js"></script>

<ul id="my_sortable">                 
  <li id="item_1">A</li>
  <li id="item_2">B</li>
  <li id="item_3">C</li>
</ul>

I had the same problem and since my sortable items contained three or four clickable items (and the number was variable) binding/unbinding them on the fly didn't really seem an option. However, by incident I specified the

helper : 'clone'

option, which behaved identically to the original sortable in terms of interface but apparently does not fire click events on the dragged item and thus solves the problem. It's as much a hack as anything else, but at least it's short and easy..

Answer

If you have a reference to the click event for your li, you can unbind it in the sortable update method then use Event/one to rebind it. The event propagation can be stopped before you rebind, preventing your original click handler from firing.

If you for some reason don't want to use the helper:'clone' trick, this worked for me. It cancels the click event on an item that is dragged. jQuery adds the class ui-sortable-helper to the dragged element.

$('.draggable').click(clickCancelonDrop);
function clickCancelonDrop(event) {
    var cls = $(this).attr('class');
    if (cls.match('ui-sortable-helper'))
         return event.stopImmediatePropagation() || false;
}
Answer
$('.selector').draggable({
    stop: function(event, ui) {
        // event.toElement is the element that was responsible
        // for triggering this event. The handle, in case of a draggable.
        $( event.toElement ).one('click', function(e){ e.stopImmediatePropagation(); } );
    }
});

This works because "one-listeners" are fired before "normal" listeners. So if a one-listener stops propagation, it will never reach your previously set listeners.

The answer by mercilor worked for me a couple of caveats. The click event was actually on the handle element rather than the sorted item itself. Unfortunately the ui object, doesn't give you a reference to the handle in the update event (feature request to jquery ui?). So I had to get the handle myself. Also, I had to call preventDefault as well to stop the click action.

update: function(ev, ui) {
    var handle = $(ui.item).find('h3');
    handle.unbind("click");
    handle.one("click", function (event) {
                            event.stopImmediatePropagation();
                            event.preventDefault();
                            $(this).click(clickHandler);
                        });
    // other update code ...

Easier, use a var to know when the element is being sorted...

We can also use a flag on the stop event that and check that flag on the click event.

var isSortableCalled = false;

$('#my_sortable').sortable({
         stop: function(event, ui){
              isSortableCalled = true;
         },
         update: function() { console.log('update') },
         delay: 30
});

$('#my_sortable li').click(function () {    
       if(!isSortableCalled){
            console.log('click');
       }
       isSortableCalled = false;

});

One solution is to use live() instead of normal binding, but Elte Hupkes solution rocks!!!!

Answer

Thanks to Elte Hupkus;

helper: 'clone' 

I have implemented the same and a sample is shown below.

$(document).ready(function() {
$("#MenuListStyle").sortable({
 helper:'clone',
 revert:true
}).disableSelection();
});
Answer
$('.menu_group tbody a').click(function(){
    link = $(this).attr('href');
    window.location.href = link;
});

This solution seems to be working for me. Now i can click on clickables inside sortable elements.

Note: ".menu_group tbody" is .sortable();
