undefined result javascript

Question

I have a simple javascript code, that validate when you write a order number and generates tags with javascript(with bootstrap-tagsinput js):

 var order = $('#order_number').val();

 if ($.inArray(order, $('#input_order_tags').val()) >= 0) {
  $('#input_order_tags').tagsinput('add', order);
  return;
 }

 var params = {
  email: email,
  order_code: order
 }

 AjaxServices.validateOrderNumberByEmail(params, function(error, result) {
  if (error)
   alert(error);
  else
   $('#input_order_tags').tagsinput('add', result.order);
 });

This works fine but, every time trigger the error message when send a order number:

Console chrome debug:

How I can avoid the error of alert?

This is not a javascript issue. Server-side in you application you use order_code in one of the calls which returns the error message you see in the ajax call. Debug the offending call server-side, see which call returns that error and adjust your code so it works properly.

There might be two possibilities

client side issue ( javascript error) if so, its because the field order_number is disabled field. as mentioned in this link undefined index on javascript dynamic variables when passing to php form If so, remove that disabled and use read-only and check if it works, without any error.
Server side issue( ajax call) if so, server side code which performs on call of that ajax call is causing that issue.
