Ajax Seitennummerierung funktioniert nicht im Codeigniter?

Question

Controller: test.php

<?php 
    defined('BASEPATH') OR exit('No direct script access allowed'); 
    class Test extends CI_Controller 
    { 
     function __construct() 
     { 
      parent :: __construct(); 
      $this->load->helper(array('form', 'url', 'captcha', 'email')); 
      $this->load->model('dependent_field'); 
      $this->load->library('curl'); 
     } 
     public function get_exam_college($offset=null) 
     { 

      $this->load->library('pagination'); 
      $config['base_url'] = base_url().'test/get_exam_college/'; 
      $config['total_rows'] = $this->dependent_field->count_field_exam_college($field); 

      $config['per_page'] = 10;

      $config['full_tag_close'] = '</ul>'; 
      $config['cur_tag_open'] = '<li class="active"><a href="javascript:void(0)">'; 
      $config['num_tag_open'] = '<li>'; 
      $config['num_tag_close'] = '</li>'; 
      $config['cur_tag_close'] = '</a></li>'; 
      $config['first_link'] = 'First'; 
      $config['first_tag_open'] = '<li>'; 
      $config['first_tag_close'] = '</li>'; 
      $config['last_link'] = 'Last'; 
      $config['last_tag_open'] = '<li>'; 
      $config['last_tag_close'] = '</li>'; 
      $config['next_link'] = FALSE; 
      $config['next_tag_open'] = '<li>'; 
      $config['next_tag_close'] = '</li>'; 
      $config['prev_link'] = FALSE; 
      $config['prev_tag_open'] = '<li>'; 
      $config['prev_tag_close'] = '</li>'; 
      $config['page_query_string'] = FALSE; 
      $this->pagination->initialize($config); 

      $field=$this->input->post('field'); 
      $data['field'] = $this->dependent_field->field_exam_college($field, $config['per_page'],$offset); 
      $this->load->view('exam-centers-colleges',$data); 
     } 
    }

    }); 
</script> 

Modell: dependent_field.php

<?php 
    class Dependent_field extends CI_Model 
    { 
     function __construct() 
     { 
     parent::__construct(); 
     } 
     public function field_exam_college($field) 
     {  
     $this->db->select('college_name, field, city, state, address, website, courses'); 
     $this->db->from('all_colleges'); 
     $where = "field = '$field'"; 
     $this->db->where($where); 
     $query = $this->db->get(); 
     $result = $query->result_array(); 
     return $result; 
     } 

     public function count_field_exam_college($field) 
     { 
     $this->db->select('college_name, field, city, state, address, website, courses'); 
     $this->db->from('all_colleges'); 
     $where = "field = '$field'"; 
     $this->db->where($where); 
     $query = $this->db->get(); 
     $result = $query->count(); 
     return $result; 
     } 
    } 

In diesem Code habe ich einen Index haben. php-Datei und ich rufe exam-collections.php-Datei an, wenn ich auf Senden klicke. Jetzt möchte ich Ajax-Seitenzahlen verwenden, aber es funktioniert immer noch nicht. Ich weiß nicht warum und wo mache ich mich falsch. Also, wie kann ich Ajax Paginierung verwenden? Bitte helfen Sie mir.

Thank

Sorry, ich habe eine Menge Code zu ändern.

<?php 
    defined('BASEPATH') OR exit('No direct script access allowed'); 
    class Test extends CI_Controller 
    { 
     function __construct() 
     { 
      parent :: __construct(); 
      $this->load->helper(array('form', 'url', 'captcha', 'email')); 
      $this->load->model('dependent_field'); 
      $this->load->library('url'); 
     } 
    public function get_exam_college($offset=null) 
    { 

     $this->load->library('pagination'); 
     $config['base_url'] = base_url().'test/get_exam_college/'; 
     $config['total_rows'] = $this->dependent_field->count_field_exam_college($field); 

     $config['per_page'] = 10; 
     $config['full_tag_open'] = '<ul class="pagination" id="search_page_pagination">'; 
     $config['full_tag_close'] = '</ul>'; 
     $config['cur_tag_open'] = '<li class="active"><a href="javascript:void(0)">'; 
     $config['num_tag_open'] = '<li>'; 
     $config['num_tag_close'] = '</li>'; 
     $config['cur_tag_close'] = '</a></li>'; 
     $config['first_link'] = 'First'; 
     $config['first_tag_open'] = '<li>'; 
     $config['first_tag_close'] = '</li>'; 
     $config['last_link'] = 'Last'; 
     $config['last_tag_open'] = '<li>'; 
     $config['last_tag_close'] = '</li>'; 
     $config['next_link'] = FALSE; 
     $config['next_tag_open'] = '<li>'; 
     $config['next_tag_close'] = '</li>'; 
     $config['prev_link'] = FALSE; 
     $config['prev_tag_open'] = '<li>'; 
     $config['prev_tag_close'] = '</li>'; 
     $config['page_query_string'] = FALSE; 
     $this->pagination->initialize($config); 

     $field = $this->input->post('field'); 
     $data['field'] = $this->dependent_field->field_exam_college($field, $config['per_page'],$offset); 
     $value['string'] = ''; 
     foreach($data['field'] as $token => $fetch) 
     { 
      $value['string'] .= ' 
        <div class="about"> 
         <ul id="list"> 
          <li>' . $fetch['college_name'] . '</li> 
          <li>' . $fetch['address'] . '</li> 
         </ul> 
        </div>'; 
     } 
     $value['pagination'] = $this->pagination->create_links(); 
     echo json_encode($value); 
    } 
} 

Modell:

<?php 
    class Dependent_field extends CI_Model 
    { 
     function __construct() 
     { 
     parent::__construct(); 
     } 
     public function field_exam_college($field) 
     {  
     $this->db->select('college_name, field, city, state, address, website, courses'); 
     $this->db->from('all_colleges'); 
     $this->db->where('field', $field); 
     $query = $this->db->get(); 
     $result = $query->result_array(); 
     return $result; 
     } 
     public function count_field_exam_college($field) 
     { 
     $this->db->select('college_name, field, city, state, address, website, courses'); 
     $this->db->from('all_colleges'); 
     $this->db->where('field', $field); 
     $query = $this->db->get(); 
     return $result->num_rows(); 
     } 
    } 

Ausblick:

<div class="col-lg-12" id = "box" > 

    </div> 
    <div id="pagination"> 

    </div> 
<script type="text/javascript"> 
    $(function(){ 
     $('body').on('click','ul#search_page_pagination > li > a',function(event){ 
      e.preventDefault(); 
      var Pagination_url = $(this).attr('href'); 
      $.ajax({ 
       url:Pagination_url, 
       type:'POST', 
       dataType: 'json', 
       success: function(data) 
       { 
        $('#box').html(data.string); 
        $('#pagination').html(data.pagination); 
        $('table').addClass('table'); 
       } 
      }); 
     }); 
    }); 
</script> 

Bitte mich daran erinnern, wenn es nicht funktioniert.
