| 17 | Usage Note: | |
| 18 | ----------- | |
| 19 | Do not use both ajaxSubmit and ajaxForm on the same form. These | |
| 20 | functions are mutually exclusive. Use ajaxSubmit if you want | |
| 21 | to bind your own submit handler to the form. For example, | |
| 22 | ||
| 23 | $(document).ready(function() { | |
| 24 | $('#myForm').on('submit', function(e) { | |
| 25 | e.preventDefault(); // <-- important | |
| 26 | $(this).ajaxSubmit({ | |
| 27 | target: '#output' | |
| 28 | }); | |
| 29 | }); | |
| 30 | }); | |
| 31 | ||
| 32 | Use ajaxForm when you want the plugin to manage all the event binding | |
| 33 | for you. For example, | |
| 34 | ||
| 35 | $(document).ready(function() { | |
| 36 | $('#myForm').ajaxForm({ | |
| 37 | target: '#output' | |
| 38 | }); | |
| 39 | }); | |
| 40 | ||
| 41 | You can also use ajaxForm with delegation (requires jQuery v1.7+), so the | |
| 42 | form does not have to exist when you invoke ajaxForm: | |
| 43 | ||
| 44 | $('#myForm').ajaxForm({ | |
| 45 | delegation: true, | |
| 46 | target: '#output' | |
| 47 | }); | |
| 48 | ||
| 49 | When using ajaxForm, the ajaxSubmit function will be invoked for you | |
| 50 | at the appropriate time. | |
