I want to create an onclick event for the radio button. Here is what I  
have:

\<%= radio\_button\_tag ‘user’, ‘d\_home’, :id =\> ‘user[d\_home]’, :onclick  
=\> “new Effect.SwitchOff(‘apear-div’); new Effect.Fade( ‘apear-div’ )”  
%\>

Now, the radio button works fine along with the other members of the  
group, is just doesn’t recognize the :onclick part. Anyone know what I’m  
missing here? Thanks,

–S

Check the APIs for radio\_button and radio\_button\_tag, you’re not  
using them correctly:

> **[ActionView::Helpers::FormHelper](https://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html#M000502)**

Try this, it should work (note (a) checked attribute ‘true’ (b) options  
within ‘{’ and ‘}’):

\<%= radio\_button\_tag ‘user’, ‘d\_home’, true, {:id =\> ‘user[d\_home]’,  
:onclick =\> “new Effect.SwitchOff(‘apear-div’); new Effect.Fade(  
‘apear-div’ )”} %\>
