【问题描述】：

我的视图中有 3 个部分，当用户选择必须仅刷新分页 div 的另一个页面链接时，我希望更改视图的一部分。我在 Codeigniter 中的简单分页代码如下，并且运行良好。

控制器：home.php

<?php
class Home extends CI_Controller {


 public function __construct() {
       parent::__construct();
        $this->load->model('MovieModel');
        $this->load->library('pagination');
    }


 public function index($offset=0){

  $config['total_rows'] = $this->MovieModel->totalMovies();

  $config['base_url'] = base_url().'/home/index';
  $config['per_page'] = 5;
  $config['uri_segment'] = '3';

  $config['full_tag_open'] = '<div class="pagination"><ul>';
  $config['full_tag_close'] = '</ul></div>';

  $config['first_link'] = '« First';
  $config['first_tag_open'] = '<li class="prev page">';
  $config['first_tag_close'] = '</li>';

  $config['last_link'] = 'Last »';
  $config['last_tag_open'] = '<li class="next page">';
  $config['last_tag_close'] = '</li>';

  $config['next_link'] = 'Next →';
  $config['next_tag_open'] = '<li class="next page">';
  $config['next_tag_close'] = '</li>';

  $config['prev_link'] = '← Previous';
  $config['prev_tag_open'] = '<li class="prev page">';
  $config['prev_tag_close'] = '</li>';

  $config['cur_tag_open'] = '<li class="active"><a href="">';
  $config['cur_tag_close'] = '</a></li>';

  $config['num_tag_open'] = '<li class="page">';
  $config['num_tag_close'] = '</li>';


  $this->pagination->initialize($config);


  if($this->uri->segment(3))
  {
    $offset = $this->uri->segment(3);
  }
  else 
  {
     $offset = 0;


  }

  $query = $this->MovieModel->getMovies(5,$offset); 

  //$query = $this->MovieModel->getMovies(5,$this->uri->segment(3));

  $data['MOVIES'] = null;

  if($query){
   $data['MOVIES'] =  $query;
  }

  $this->load->view('index1.php', $data);
 }
}
?>

MovieModel.php

<?php
class MovieModel extends CI_Model {


 function getMovies($limit=null,$offset=NULL){
  $this->db->select("MOVIE_ID,FILM_NAME,DIRECTOR,RELEASE_YEAR");
  $this->db->from('trn_movies');
  $this->db->limit($limit, $offset);
  $query = $this->db->get();

  return $query->result();
 }

 function totalMovies(){
  return $this->db->count_all_results('trn_movies');
 }
}
?>

index1.php

        <?php 
        if(is_array($MOVIES) && count($MOVIES) ) {
         foreach($MOVIES as $movie){     
        ?>
        <tr><td><?=$movie->MOVIE_ID;?></td><td><?=$movie->FILM_NAME;?></td><td><?=$movie->DIRECTOR;?></td><td><?=$movie->RELEASE_YEAR;?></td></tr>     
           <?php 
         }        
        }?>  
       </table>            
      </div>
     </div>
    </div>
    <div class="row">
              <div class="col-md-12">
      <div class="row"><?php echo $this->pagination->create_links(); ?></div> 
     </div>
    </div>
   </div>    
  </body>
 </html>

【解决方案1】：

这不能仅在 PHP 中完成。

您必须使用 AJAX 来更新页面上的部分。

建议的方法是：

使用 jQuery 检测按钮点击。
向您的 Codeigniter 后端发送请求。
jQuery 检测成功，使用后端打印的数据更新前端的容器。
