-   Usage Note:
-   -----------
-   Do not use both ajaxSubmit and ajaxForm on the same form.  These
-   functions are mutually exclusive.  Use ajaxSubmit if you want
-   to bind your own submit handler to the form.  For example,
-
-   $(document).ready(function() {
-   $('#myForm').on('submit', function(e) {
-   e.preventDefault(); // <-- important
-   $(this).ajaxSubmit({
-   target: '#output'
-   });
-   });
-   });
-
-   Use ajaxForm when you want the plugin to manage all the event binding
-   for you.  For example,
-
-   $(document).ready(function() {
-   $('#myForm').ajaxForm({
-   target: '#output'
-   });
-   });
-
-   You can also use ajaxForm with delegation (requires jQuery v1.7+), so the
-   form does not have to exist when you invoke ajaxForm:
-
-   $('#myForm').ajaxForm({
-   delegation: true,
-   target: '#output'
-   });
-
-   When using ajaxForm, the ajaxSubmit function will be invoked for you
-   at the appropriate time.
