JS undefined error on vertical.tabs.js line 9

Loop on line 8 is grabbing some selectors that don't have a name attr. Causing an error on line 8 "Uncaught TypeError: Cannot call method 'replace' of undefined".

var default_name = $(this).attr('name').replace(/\[value\]/, '[default]');

This error is stopping other javascript on the page to load. Such as ckeditor on field_body.

Provided patch to add a check if the field name is defined.

var input_field = $(this).attr('name');
if(input_field === undefined ) {
  return false;
}
var default_name = input_field.replace(/\[value\]/, '[default]');
