Are you allowed to use the javascript\_include\_tag to include  
javascript files for specific views? I have included the default  
javascript files in the element of my site layout file, but  
when I try and include a javascript file for a specific view within a  
new element in that view it does not work. I guess my question  
is: is it okay to create separate elements for specific views?  
Will all the code get rendered that is within these new   
elements and the elements in my layout file? or will there be  
a conflict?

Yes, you are allowed to use the javascript\_include\_tag to include  
javascript  
files for specific view templates. Can you post your code so that  
people  
can better assist you because I don’t follow your question.

so would the following be redundant then?

\<% content\_for :javascript do %\>  
\<%= javascript\_tag “new javascript function” %\>  
\<% end %\>

assuming i have \<%= yield :javascript %\>

in my main layout file.
