CodeIgniter AJAX分页删除问题

$route['ajax/delete'] = 'ajax/delete';

class Ajax extends CI_Controller {
    public function delete() {
        // 解析AJAX请求参数
        $id = $this->input->post('id');

        // 执行删除操作
        $result = $this->db->delete('table_name', array('id' => $id));

        // 返回响应
        if ($result) {
            $response = array('status' => 'success', 'message' => '删除成功');
        } else {
            $response = array('status' => 'error', 'message' => '删除失败');
        }

        echo json_encode($response);
    }
}

$.ajax({
    url: '/ajax/delete',
    type: 'POST',
    data: {id: 1},
    dataType: 'json',
    success: function(response) {
        if (response.status === 'success') {
            alert(response.message);
        } else {
            alert(response.message);
        }
    },
    error: function() {
        alert('请求失败');
    }
});
