How to show div with radio button onclick


I am trying to get a div to show when a radio button is clicked but
the problem is that the div is dynamically named. I am using the
normal html for a radio button:

Because observe field does not work well with radio buttons. I have
tried adding an onclick with the div id:

But the #{} does not get rendered and I have had a lot
trouble figuring out how to do this. I think I need to use some sort
of inline RJS? Im not sure, does anyone have any ideas?



this should do it. You are inside HTML code and not inside a ruby
string, so the #{} syntax won’t work. Instead you have to use the Erb
sequence <%= %>
