Answer 1

Ashirvad's answer no longer works. Note the class name changes and using the option element instead of the li element. I've updated my answer to not use the deprecated "success" event, instead opting for .done():

$('.chosen-search input').autocomplete({
    minLength: 3,
    source: function( request, response ) {
        $.ajax({
            url: "/some/autocomplete/url/"+request.term,
            dataType: "json",
            beforeSend: function(){ $('ul.chosen-results').empty(); $("#CHOSEN_INPUT_FIELDID").empty(); }
        }).done(function( data ) {
                response( $.map( data, function( item ) {
                    $('#CHOSEN_INPUT_FIELDID').append('<option value="blah">' + item.name + '</option>');
                }));

               $("#CHOSEN_INPUT_FIELDID").trigger("chosen:updated");
        });
    }
});

Answer 2

This might be helpful. You have to just trigger an event.

$("#DropDownID").trigger("liszt:updated");

Where "DropDownID" is ID of <select>.

try this:

$('.chzn-choices input').autocomplete({
  source: function( request, response ) {
    $.ajax({
      url: "/change/name/autocomplete/"+request.term+"/",
      dataType: "json",
      beforeSend: function(){$('ul.chzn-results').empty();},
      success: function( data ) {
        response( $.map( data, function( item ) {
          $('ul.chzn-results').append('<li class="active-result">' + item.name + '</li>');
        }));
      }
    });
  }
});

Answer 4

If you are generating select tag from ajax, add this inside success function:

$('.chosen').chosen();

Or, If you are generating select tag on clicking add more button then add:

$('.chosen').chosen();

inside the function.

Answer 5

Like Vicky suggested, Select2 comes with the AJAX features inbuilt and looks like a great plugin.

If you dont want to switch from Chosen, try AJAX-Chosen https://github.com/meltingice/ajax-chosen

var object = $("#lstValue_chosen").find('.chosen-choices').find('input[type="text"]')[0];
var _KeyCode = event.which || event.keyCode;
if (_KeyCode != 37 && _KeyCode != 38 && _KeyCode != 39 && _KeyCode != 40) { 

    if (object.value != "") {
        var SelectedObjvalue = object.value;
        if (SelectedObjvalue.length > 0) {
            var obj = { value: SelectedObjvalue };
            var SelectedListValue = $('#lstValue').val();
            var Uniqueid = $('#uniqueid').val();

            $.ajax({
                url: '/Admin/GetUserListBox?SelectedValue=' + SelectedListValue + '&Uniqueid=' + Uniqueid,
                data: { value: SelectedObjvalue },
                type: 'GET',
                async: false,
                success: function (response) {
                    if (response.length > 0) {
                        $('#lstValue').html('');
                        var options = '';                            
                        $.each(response, function (i, obj) {
                            options += '<option value="' + obj.Value + '">' + obj.Text + '</option>';
                        });
                        $('#lstValue').append(options);
                        $('#lstValue').val(SelectedListValue);
                        $('#lstValue').trigger("chosen:updated");
                        object.value = SelectedObjvalue;
                    }
                },
                error: function (xhr, ajaxOptions, thrownError) {
                    //jAlert("Error. Please, check the data.", " Deactivate User");
                    alert(error.StatusText);
                }
            });
        }
    }
}
