在nette中通过AJAX使用带有数据的select2插件进行多选返回一个空数组

<select id="mySelect" multiple="multiple">
  <option value="1">Option 1</option>
  <option value="2">Option 2</option>
  <option value="3">Option 3</option>
</select>

<script>
$(document).ready(function() {
  $('#mySelect').select2({
    ajax: {
      url: 'your_ajax_endpoint',
      dataType: 'json',
      processResults: function(data) {
        return {
          results: data
        };
      }
    }
  });
});
</script>

public function handleAjaxRequest()
{
  $data = [
    ['id' => 1, 'text' => 'Option 1'],
    ['id' => 2, 'text' => 'Option 2'],
    ['id' => 3, 'text' => 'Option 3']
  ];

  echo json_encode($data);
  exit;
}

$router->addRoute('GET', 'your_ajax_endpoint', 'YourController:handleAjaxRequest');

$('#mySelect').on('change', function() {
  var selectedValues = $(this).val();

  $.ajax({
    url: 'your_backend_handler',
    type: 'POST',
    data: { selectedValues: selectedValues },
    success: function(response) {
      console.log(response);
    }
  });
});
