-    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.
