I just played a little with the SUCondition which is clearly the key
to my problem (sorry I didn't saw it before). I have a problem though.
If I use an evaluator as the condition, the result is returned in
The following code always shows an alert :
html scriptaculous script alert: 'test !'; condition: (html evaluator
callback: [:s | false])
I tried to add an '== ''false''' in several ways inside the condition,
but I can't manage to get something to work.
So I add a new SUStatement named SUEquals with this method :
super printContentOn: aStream.
So now this script doesn't show an alert :
html scriptaculous script alert: 'test !'; condition: ((html evaluator
callback: [:s | false]) equals: 'false')
Was this possible without the creation of the SUEquals class ?
