Hi all,

I’m using a set of radio buttons, which when selected will transfer the  
control to a javascript function. But the issue is that the javascript  
function isn’t triggered. Is there any error in my code?

Given below is the code.

\<% @types.each do |type|%\> #@types was declared in the controller  
\<%= type.name %\>\<input type=“radio” name= “type”  
value= \<%type.id\>onclick= “myfunc();”\>  
\<% end %\>

The above code is in a partial and the javascript function is in an  
rhtml page.

My javascript function

\<%= javascript\_include\_tag “prototype” %\>  
\<%= javascript\_include\_tag “defaults” %\>

I have no clue on why this is happening and I believe someone can help  
me.  
Thanks  
Chris

> value= \<%type.id\>onclick= “myfunc();”\>

… the way the code is pasted here on the forum, it seems there is an  
error with some spacings…(the onclick is the continuation of the value  
attribute, and there are no qoutes on value (as well as a ‘=’ to display  
the type.id output):

\<input type=“radio” name=“type” value="\<%= type.id %\>  
onclick=“myfunc();” /\>
