  • ajaxForm() provides a mechanism for fully automating form submission. *
  • The advantages of using this method instead of ajaxSubmit() are: *
  • 1: This method will include coordinates for <input type="image" /> elements (if the element
  • is used to submit the form).
  • 2. This method will include the submit element's name/value data (for the element that was
  • used to submit the form).
  • 3. This method binds the submit() method to the form for you. *
  • The options argument for ajaxForm works exactly as it does for ajaxSubmit. ajaxForm merely
  • passes the options argument along after properly binding events for submit elements and
  • the form itself. */
