选择选项值 id 并使用 javascript & codinator 在值中显示其他输入框

Question

我正在使用 codinator 选择 id 显示值其他输入框但不显示任何值。请帮助...

在此处选择选项查看页面代码

工作正常

<select  id="tanktype" name="tankno" class="form-control tankno" required >

    <option>Select</option>

     <?php

       $queryw = $this->db->where('vh_rdi',$_SESSION['rdi']);

       $queryw = $this->db->get('vh_stock');

       if ($queryw->num_rows() > 0)  

         {

         foreach ($queryw->result() as $roww)

           {

     ?>                             

    <option value="<?php echo $roww->vh_id; ?>"><?php echo $roww->vh_id; ?></option>

   <?php } } ?>

</select>

结果显示视图字段相同的页面但不显示任何值

<input   name="vh_stock"  type="text" class="vh_stock" value="">

JavaScript 代码在这里

alert('ajax completed. Response: '+data) 很好，但在 vh_stock 获取值后不显示

<script>

        $(document).ready(function(){

        $('#tanktype').change(function(){

            //Selected value

            var id = $(this).val();

            alert("value in js "+id);

            //Ajax for calling php function

            $.post('<?php echo base_url()."index.php/Mechanical_rdirecived/viewtankstock"; ?>', { dropdownValue: id }, function(data){

                alert('ajax completed. Response:  '+data);//working fine result

                //do after submission operation in DOM

                 $(".vh_stock").val(data.vh_stock); //value is not getting 

                 //$(".id1").val(data.id1);                      

              //}, 'json')

            });

        });

});

    </script>  

控制器 => Mechanical_rdirecived/viewtankstock

工作正常

public function viewtankstock()  

{ 

$id = $this->input->post('dropdownValue');

$this->load->model('Model_fuel_rdirecived');

$this->Model_fuel_rdirecived->viewtankstock($id);

}

模型=>Model_fuel_rdirecived->viewtankstock($id);
