14 | | Usage Note: |
15 | | ----------- |
16 | | Do not use both ajaxSubmit and ajaxForm on the same form. These |
17 | | functions are intended to be exclusive. Use ajaxSubmit if you want |
18 | | to bind your own submit handler to the form. For example, |
19 | | |
20 | | $(document).ready(function() { |
21 | | $('#myForm').bind('submit', function(e) { |
22 | | e.preventDefault(); // <-- important |
23 | | $(this).ajaxSubmit({ |
24 | | target: '#output' |
25 | | }); |
26 | | }); |
27 | | }); |
28 | | |
29 | | Use ajaxForm when you want the plugin to manage all the event binding |
30 | | for you. For example, |
31 | | |
32 | | $(document).ready(function() { |
33 | | $('#myForm').ajaxForm({ |
34 | | target: '#output' |
35 | | }); |
36 | | }); |
37 | | |
38 | | When using ajaxForm, the ajaxSubmit function will be invoked for you |
39 | | at the appropriate time. |

561 | | * |
562 | | * 1: This method will include coordinates for <input type="image" /> elements (if the element |

568 | | * The options argument for ajaxForm works exactly as it does for ajaxSubmit. ajaxForm merely |
569 | | * passes the options argument along after properly binding events for submit elements and |
