How to get value of select2:unselect

rated 0 times [ 132] [ 2] / answers: 1 / hits: 33915 / 9 Years ago, fri, december 25, 2015, 12:00:00

how can I get value of unselected option in Select2 using select2:unselect

$('#mySelect').on(select2:unselect, function(e){



    var unselected_value = $('#mySelect').val(); // using this shows 'null'

    // or using below expression also shows 'null'

    var unselected_value = $('#mySelect :selected').val();



    alert(unselected_value);

}).trigger('change');

in above code alert shows 'null'

I need to use select2:unselect because 'change' event will sense :select and :unselect both.

Finally, I've got the solution and that is:
The value of unselected option is only available before it is unselected. Not at select2:unselect rather at select2:unselecting
now the code will be:

$('#mySelect').on(select2:unselecting, function(e){

         var unselected_value = $('#mySelect').val();

         alert(unselected_value);

    }).trigger('change');
