+ 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.
