使用ajax

标签： php jquery ajax codeigniter

我在codeigniter中通过ajax使用搜索功能...代码工作正常...它正确搜索所需的匹配但我的代码的问题是它在视图中显示2个东西1.默认值2 .searched值 但我想要的是，当我搜索时，它只显示默认值，然后只显示搜索值而不是默认值。 我的控制器是：

public function seller()
{
    $this->load->model('home/Home_model');
    $ser = $this->input->post('search_data');
   if(isset($search))
   {
    $data['h'] = $this->Home_model->search_seller($search);     
    }
    else
    {
    $data['h'] = $this->Home_model->seller();       
    }
    $this->load->view('admin/pages/sellers', $data);    
}

我的模特是

      public function seller()  
  {  
     $query = $this->db->get('wc_seller');  
     return $query;  
  } 
    public function search_seller($search)
    {
    $this->db->select('*');
    $this->db->like('seller_name', $search);
    $this->db->like('email', $search);
    $query = $this->db->get('wc_seller');
     return $query;

} 视图是

foreach ($h->result() as $row)  
     {  
        ?>
        <form action="<?php echo base_url() . "Home/edit_sellers/" . $row->id; ?>" method="POST">
                <tr>
                    <th scope="row"><?php echo $i; ?></th>
                    <td><?php echo $row->last_modified;?> </td>
                    <td><?php echo $row->email; ?></td>
                    <input type="hidden" name="id" value="<?php echo $row-> id; ?>">
                    <td><input type="text" name="seller_name" value="<?php echo $row->seller_name;?>" placeholder="<?php echo $row->seller_name;?>" class="form-control"></td>
                    <td><input type="text" name="mobile_no" value="<?php echo $row->mobile_no;?>" placeholder="<?php echo $row->mobile_no;?>" class="form-control"></td>
                    <td>
  </form>
    <?php } ?>

我的ajax脚本是

       <?php $this->load->view('admin/templates/header'); ?>       

 <div id="page-wrapper">
<div class="graphs">
<h3 class="blank1">All Sellers</h3>
<div class="something">

    <div id="suggestions">
        <div id="autoSuggestionsList">

    </div>
  </div>
  <div class="xs tabls tabls1">
     <div class="panel-body1">
         <table class="table table-hover table-responsive">

原因是您正在将搜索结果添加到同一个视图文件中。因此，请尝试以下方法： - 

Create one new view file someName.php and paste the following code.

    <div class="panel-body1">
        <table class="table table-hover table-responsive">
            <thead>
                <tr>
                <th>Id</th>
                <th>Registered On</th>
                <th>Email</th>
                <th>Full Name</th>
                <th>Mobile No</th>
                <th>Actions</th>
            </tr>
        </thead>
        <tbody>
<?php  
$i = 1; 
 foreach ($h->result() as $row)  
 {  
    ?>
    <form action="<?php echo base_url() . "Home/edit_sellers/" . $row->id; ?>" method="POST">
            <tr>
                <th scope="row"><?php echo $i; ?></th>
                <td><?php echo $row->last_modified;?> </td>
                <td><?php echo $row->email; ?></td>
                <input type="hidden" name="id" value="<?php echo $row-> id; ?>">
                <td><input type="text" name="seller_name" value="<?php echo $row->seller_name;?>" placeholder="<?php echo $row->seller_name;?>" class="form-control"></td>
                <td><input type="text" name="mobile_no" value="<?php echo $row->mobile_no;?>" placeholder="<?php echo $row->mobile_no;?>" class="form-control"></td>
                <td>

                <button type="submit" value="Update" class="btn btn-primary btn-sm">Update</button>
                <a type="button" class="btn btn-danger btn-sm" href="<?php echo base_url() . "Home/delete_seller/" . $row->id; ?>" onclick="return confirm('Are you sure you want to delete it?')"><i class="fa fa-trash-o" aria-hidden="true"></i></a>

                <?php if($row->status == '1' ){
                $status = 'Deactivate';
                }
                else{
                    $status = 'Activate';

                }
                ?>
                <button type="button" class="btn btn-success btn-sm" id="<?php echo $row->id; ?>"  onclick="savestatus<?php echo $row->id; ?>(<?php echo $row->id; ?>)"><?php echo $status; ?></button>
                </td>
            </tr>
        </form>
    </tbody>
    </table>
    </div>

更改您的默认视图文件： - 

<?php $this->load->view('admin/templates/header'); ?>       

<div id="page-wrapper">
<div class="graphs">
<h3 class="blank1">All Sellers</h3>
<div class="something">
<input name="search_data" id="search_data" type="text" onkeyup="ajaxSearch();">
</div>
<div class="xs tabls tabls1" id="suggestions">
 <div class="panel-body1">
     <table class="table table-hover table-responsive">

                <th>Mobile No</th>
                <th>Actions</th>
            </tr>
        </thead>

                <?php if($row->status == '1' ){
                $status = 'Deactivate';
                }
                else{
                    $status = 'Activate';

                }
                ?>
                <button type="button" class="btn btn-success btn-sm" id="<?php echo $row->id; ?>"  onclick="savestatus<?php echo $row->id; ?>(<?php echo $row->id; ?>)"><?php echo $status; ?></button>

   $("#"+row_id).text().trim()==="Activate"?         $("#"+row_id).text("Deactivate"):$("#"+row_id).text("Activate")

}

</script>

    <?php 
     $i++;

    }  

      ?> 
        </tbody>
    </table>

</div>

    if (input_data.length === 0) {
        $('#suggestions').hide();
        //$('.tabls1').show();
    } else {

        var post_data = {
            'search_data': input_data,
            '<?php echo $this->security->get_csrf_token_name(); ?>': '<?php echo $this->security->get_csrf_hash(); ?>'

            }
        });

    }
   }
</script>
<?php $this->load->view('admin/templates/footer'); ?>

在控制器中

public function seller()
{
$this->load->model('home/Home_model');
$ser = $this->input->post('search_data');
if(isset($search))
{
    $data['h'] = $this->Home_model->search_seller($search);     
    $this->load->view('admin/pages/someName', $data); 
}
else
{
    $data['h'] = $this->Home_model->seller();       
    $this->load->view('admin/pages/sellers', $data); 
}

}
