| 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. |
