+ Usage Note: \r
+ -----------\r
+ Do not use both ajaxSubmit and ajaxForm on the same form. These\r
+ functions are intended to be exclusive. Use ajaxSubmit if you want\r
+ to bind your own submit handler to the form. For example,\r
+\r
+ $(document).ready(function() {\r
+ $('#myForm').bind('submit', function() {\r
+ $(this).ajaxSubmit({\r
+ target: '#output'\r
+ });\r
+ return false; // <-- important!\r
+ });\r
+ });\r
+\r
+ Use ajaxForm when you want the plugin to manage all the event binding\r
+ for you. For example,\r
+\r
+ $(document).ready(function() {\r
+ $('#myForm').ajaxForm({\r
+ target: '#output'\r
+ });\r
+ });\r
+ \r
+ When using ajaxForm, the ajaxSubmit function will be invoked for you\r
+ at the appropriate time. \r
