- 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(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'
- });
- });
- When using ajaxForm, the ajaxSubmit function will be invoked for you
- at the appropriate time.
