Question

In Rails 3.1, what is a neat way to include a javascript file for only some views and exclude it from others?

Answer 1

In the view you want the script,

<%- content_for :javascript do -%> 
  <script type="text/javascript"> ... </script>
<%- end -%>

An alternative to the above, I use a javascript_include_tag pointing to the js file for that script instead of using the tag so that I can keep all my javascript in one place.

<%- content_for :javascript do -%> 
  <%= javascript_include_tag "example.js" %>
<%- end -%>

In the layout for that view where you have your other javascript:

   <%= yield :javascript %>
