How to empty select2 previous data?

I have 2 select2 component in my project. Values of one of them is depended on value of other one which is selected. Here is the code:

  $('#states').on('change', function() {
     $.get({
            url: 'https://mydomain/cities.php/?sid='+$(this).val(),
            dataType: 'json',
            success: function(response) {
                citiesData = new Array();
                $.each(response, function(index, el) {
                   citiesData.push({'id' : el.id, 'text' : el.title});
                });

                $('#cities').select2({data:citiesData});
            }

        });
  });

Problem is select2 which shows cities doesn't get empty for each change of states and cities of selected state is added to pre-selected state.

How can I empty select2 of cities before inserting new data?

Try this in your ajax success function.

$('#cities').select2().val();

And to empty the select2

$("#cities").empty();
