/**

• 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
