Form submit (non ajax) only certain form fields?

Form submit (non ajax) only certain form fields?

Trying to find out if it is possible to submit a form (not ajax submit) and only submit certain form fields. I know it is possible with an ajax submit like:

  1. var post_data = $("SELECTION").serialize();
  2. $.ajax({
  3.        type :  'POST',
  4.         url  :  'script/post.php',
  5.         data :  post_data,
  6.         dataType : "text",
  7.         success: successfunction
  8. });
Now is it possible with a regular form submit in jquery?
