[Seaside] [Scriptaculous] Configure element's class frominsidetheupdater?

[Boris Popov]

Lukas,

1. It's the formatter, really :)

2. Okay, cool.

3. How do you define onSuccess? I've tried the following with the
non-existing 'bag', but don't see the error in the Firefox's JavaScript
console, which prompts me to think that its not being called. Am I using a
wrong protocol for this? The request itself works just fine.

(html request)
  triggerForm: fid;
  onSuccess: 'bah()';
  yourself 

Cheers!

-Boris

Yeah, interesting process. I experienced similar trial-and-error exercises
;-)

1. Your brackets and semicolons are very strangely placed. I think
they are probably wrong and cause some problems.

2. You don't need "html evaluator" if you don't inject a script into
the web-page, just use "html request" for simple requests.

3. The AJAX objects (request, updater, evaluator, etc.) understand a
set of events, such as #onComplete:, #onFailure:, #onSuccess:, etc. I
would use one of these events (probably #onSuccess:) to change the
class of your element. Maybe write a helper function in JavaScript
that takes the element and the checkbox as parameters and toggles the
classes appropriately. Then you can attach this function to the event
handler.

Hope this helps,
Lukas
