Rails spinoffs - Sep 2005 - radio buttons and event obvsering

Hi,

 

I made a little utility class that turns on a particular div when a
radio button is clicked - a RadioButtonDivToggler.  As the name
hopefully suggests, when a radio button from the same group is clicked,
a different div is made visible and the others are hidden.  In essence,
it toggles on (makes visible) the div associated with the radio button
from a group that you clicked.  However, I''m having problems with the
radio buttons not actually setting their "checked" value correctly (I
click button C, then click button B, but then B and C were both
selected!).  The buttons are definitely in the same group (they have the
same name attribute).  Yes, I double-checked that ;-)

 

The event observing is just this:

Event.observe(this.buttons[i],''click'',this.onChange.bindAsEventListener(
this));

 

I had to do a crazy hack in my object''s onChange method to unselect the
other radio buttons in the group by hand - it''s slightly ridiculous.
And I don''t call Event.stop anyway.  

 

Any suggestions on where I might be mucking things up and leading to a
radio button not acting like a member of a radio button group?  Is it a
side effect of Event.observe, or some unrelated nonsence?

 

Thanks,

 

Rahul

You radio buttons have to have the same name in the html attributes.
