通过隐藏在laravel中的数据

Question

我使用数据库创建了下拉列表，我希望以隐藏的方式发送“ center_code”值传递，而不在下拉列表中显示该值。

我的代码

<label for="student_course" control-label>STATE</label>

<div class="form-group">
  <select required name="state" id="state" class="form-control input-lg dynamic" data-dependent="district">
    <option value=""></option>
    @foreach($state as $states)
    <option value="{{ $states->state }}">{{ $states->state }}</option>
    @endforeach
  </select>
</div>


</div>
<div class="col-md-6">


  <label for="qualification" control-label>DISTRICT</label>

  <div class="form-group">
    <select required name="district" id="district" class="form-control input-lg dynamic" data-dependent="taluk">
      <option value=""></option>
    </select>
  </div>
</div>
<div class="col-md-6">

  <label for="qualification" control-label>TALUK</label>

  <div class="form-group">
    <select required name="taluk" id="taluk" class="form-control input-lg  dynamic" data-dependent="center_name">
      <option value=""></option>
    </select>
  </div>


</div>




<div class="col-md-6">


  <label for="center_name" control-label>CENTER NAME</label>

  <div class="form-group">
    <select required name="center_name" id="center_name" class="form-control dynamic" data-dependent="center_code">
      <option value=""></option>
    </select>
  </div>


</div>

<input name="center_code" id="center_code" class="form-control input-lg" type="text" value="{{($(this))}}">

<div class="col-md-6">




  <div class="form-group">
    <select required name="center_code" id="center_code" class="form-control input-lg">
      <option value=""></option>
    </select>
  </div>

  {{ csrf_field() }}
</div>

</div>

脚本

<script>
$(document).ready(function(){

 $('.dynamic').change(function(){
  if($(this).val() != '')
  {
   var select = $(this).attr("id");
   var value = $(this).val();
   var dependent = $(this).data('dependent');
   var _token = $('input[name="_token"]').val();
   $.ajax({
    url:"{{ route('dynamicdependent.fetch') }}",
    method:"POST",
    data:{select:select, value:value, _token:_token, dependent:dependent},
    success:function(result)
    {
     $('#'+dependent).html(result);
    }

   })
  }
 });

  $('#state').change(function(){
  $('#district').val('');
  $('#taluk').val('');
  $('#center_name').val('');
  $('#center_code').val('');

 });

 $('#district').change(function(){
  $('#taluk').val('');
  $('#center_name').val('');
    $('#center_code').val('');
 });


});
</script>
