|     Usage Note:
 | |
|     -----------
 | |
|     Do not use both ajaxSubmit and ajaxForm on the same form.  These
 | |
|     functions are intended to be exclusive.  Use ajaxSubmit if you want
 | |
|     to bind your own submit handler to the form.  For example,
 | |
| 
 | |
|     $(document).ready(function() {
 | |
|         $('#myForm').bind('submit', function() {
 | |
|             $(this).ajaxSubmit({
 | |
|                 target: '#output'
 | |
|             });
 | |
|             return false; // <-- important!
 | |
|         });
 | |
|     });
 | |
| 
 | |
|     Use ajaxForm when you want the plugin to manage all the event binding
 | |
|     for you.  For example,
 | |
| 
 | |
|     $(document).ready(function() {
 | |
|         $('#myForm').ajaxForm({
 | |
|             target: '#output'
 | |
|         });
 | |
|     });
 | |
| 
 | |
|     When using ajaxForm, the ajaxSubmit function will be invoked for you
 | |
|     at the appropriate time.

|  * 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
