+/*
+ 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.

+ * 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
