                            <div class="form-group">

                            </div>
                        </div>
                    </div>
              </div>

I am trying to populate all these fields from the json response from my ajax call.. whenever I try to target directly the element using the class.. all appended elements with the same class is populated with same value. I only want the closest elements be populated from my ajax call.

here's my javascript code

$('body').on('change','.product_name', function(){
    var product_id = $(this).find('option:selected').val();
    $.ajax({
        url : selectproduct,
        type: 'POST',
        data:{
          _token : token,
          product_id : product_id
        },
        beforeSend: function(){
          console.log('loading');
        },
        success: function(response){
          console.log(response);
            $(this).next('.row').find('.shipping_mark').val(response.product.shipping_mark);
        }
    });
  });

@pawankumar I also tried did but no luck.. I'm still figuring out the solution for this.. I'm running out of ideas.. — Kim Carlo

this inside ajax success refers to a different object. you need to save the original reference in a variable.

$('body').on('change','.product_name', function(){
    var product_id = $(this).find('option:selected').val();
    var self = this; // save reference in a variable
    $.ajax({
        url : selectproduct,
        type: 'POST',
        data:{
          _token : token,
          product_id : product_id
        },
        beforeSend: function(){
          console.log('loading');
        },
        success: function(response){
          console.log(response);//Use the saved reference in next line
            $(self).next('.row').find('.shipping_mark').val(response.product.shipping_mark);
        }
    });
  });
