Get original parent ID if JQuery sortable element is moved from one parent to another-CodePudding

I am using the JQuery UI sortable plugin, using the "connect with" functionality to allow LI elements to be moved between two different parent lists.

I am trying to produce an alert showing the ID of the original list from which the LI element was contained when a list item is moved from either #sortable1 to #sortable2 or visa versa.

The Jquery I am trying to use this as follows:

$( function() {
$( "#sortable1, #sortable2" ).sortable({
  connectWith: ".connectedSortable", 
  receive: function(e, ui) {
  alert(ui.originalPosition.id);
 }
}).disableSelection();
});

Currently this produced a undefined output, rather than #sortable1 to #sortable2.

I have included below a sample script recreating the issue I am having.

CodePudding user response：

The ui object (Sortable) has a sender jQuery object that has as the originating element.

Set your alert to this: ui.sender[0].id and you'll have it.
