    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
 | 
						|
 * passes the options argument along after properly binding events for submit elements and
 | 
						|
 * the form itself.
