                var $values = jQuery.map(enabled.find('li'),function(item){
                    return $(item).data('value');
                });
                field.val($values.join(','));
            }
        }).disableSelection();
        disabled.sortable({
            connectWith: enabled,
            dropOnEmpty: true,
            placeholder: 'ddmultiselect-placeholder',
            items: 'li'
        }).disableSelection();

Can anybody point me in the right direction? Thank you.

Solution

  • You see the warning message because the $.unique() method is indeed deprecated. If you aren't explicitly using it then I would assume it's being used internally by jQueryUI, or some other library you've included in the page. To remove the message you may need to update these libraries, if they have newer versions available.

    Note that this message is not an error, and will not currently cause any functionality to break within your page.
