[html-formfu] Checkbox attributes

[kewei xiao]

Hi Carl

     Is there any way I can call a javascript function when a checkbox 
is checked.  In my app, I have a group of checkbox reside in scrollable 
box, when one of the checkbox is checked, a javascript function will be 
called and display a proper box below.  But I don't wanna the box to be 
shown when the checkbox is unchecked.  I have tried to use
 
     attributes_xml => { onclick => "calledFunction()" } OR 
attributes_xml => { onchange => "calledFunction()" },  none of them work 
as I expect.

Hopefully you can give me some hints.  Thanks
