- 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
