- 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.
