Notifications of selection?

James T. Savidge-2
Greetings,

I’m trying to put together a query criteria selection page, and if I
have a multiSelect list, is there a way that I can be informed each
time a selection is made?

I want to fill a secondary selection list on the fly, based on the
selection(s) in the first list, but I’d rather that the user didn’t
have to push a button to get the second list populated.

Can this be done, and if so, are there any WebVelocity or Seaside
examples that I can use as a starting point?

You'd need to use ajax to catch the onChange event on the list. I'm sure there are jQuery examples of exactly this in Seaside.

Cheers,
Michael

That‘s what I figured as I continued my research, but I must not have it coded
correct yet because my breakpoint is not getting hit.

     html form: [
         html multiSelect
                 list: ... ;
                 labels: [ :each | each name ];
                 onChange: ( html jQuery ajax callback: [ :selection | selection
halt. ] ). ].

I’ll keep looking.
