Codeigniter通过Button向Datatable提交Ajax结果不起作用

<button id="submitBtn">提交</button>

$(document).ready(function() {
  $('#submitBtn').click(function() {
    $.ajax({
      url: 'your_ajax_url',
      type: 'POST',
      data: {param1: 'value1', param2: 'value2'},
      success: function(response) {
        // 处理成功响应
      },
      error: function(xhr, status, error) {
        // 处理错误响应
      }
    });
  });
});

class YourController extends CI_Controller {
  public function ajaxSubmit() {
    $param1 = $this->input->post('param1');
    $param2 = $this->input->post('param2');

    // 处理数据并返回结果
    $result = $this->your_model->processData($param1, $param2);

    // 将结果转换为JSON格式并发送回前端
    echo json_encode($result);
  }
}

$route['your_ajax_url'] = 'your_controller/ajaxSubmit';
