Which is the best way to add a page-specific JavaScript code in a Rails
3 app?
<%= f.radio_button :rating, 'positive', :onclick => "$('some_div').show();"
%>

<% content_for :head do %> <script type="text/javascript"> <%= render :partial => "my_view_javascript" </script> <% end %> Then in layout file <head> ... <%= yield :head %> </head>

In the application_helper.rb file: def include_javascript (file) s = " <script type=\"text/javascript\">" + render(:file => file) + "</script>" content_for(:head, raw(s)) end Then in your particular view (app/views/ books/index.html.erb in this example) <% include_javascript 'books/ index.js' %>

In the controller: def get_script render :file => 'app/assessts/javascripts/' + params[:name] + '.js' end def get_page @script = '/' + params[:script_name] + '.js?body=1' render page end In View <script type="text/javascript",:src => @script>
