Hi Esteban,
Add the following to your select:
html select
...
onChange: (html jQuery ajax
serializeThisWithHidden;
script: [:s | s << ((s jQuery id: id) html: [:r | self renderNewContentOn: r]) ]
In short:
- trigger a serialization of the select input element, followed by the generation of a script that replaces the div contents
- both these operations can be done using a single ajax request
- serializeThisWithHidden is Seaside-specific because a hidden element needs to be generated with selects and checkboxes.
If you want to serialize an entire form, starting from the submit button, then use #serializeForm (in a click handler on the submit button).
And yes, you need to prevent form submission in that case using a 'return false'.
Hope this helps
Johan
