Something similar to what I wrote below is what has worked for me in the
past using Pharo/Gemstone & Seaside 3. When using checkboxes you
probably want onClick rather than onChange because IE does not register
the change until the checkbox loses focus. I haven't tried a
multiselect. And there is likely a better/cleaner way to do this.
id: (id := html nextId);
((html jQuery ajax)
script: [ :s | s << (s jQuery id: 'target-div') load: [ :h | self
renderTarget: h ] ]);
callback: [ :value | cbox:=value ].
with: 'checkbox test'.
with:[self renderTarget: html].
cbox ifTrue:[html render:'Box is checked'] ifFalse:[html render:'Box
is not checked']
If you want to test the above you'd need an ivar in your component named
#cbox. Also I'm not sure about this but I thought that if you use
labels rather than the trailing #with: your user can click the entire
label to trigger the change in the check box.
