Javascript file for only some views in Rails 3.1

Question

在Rails 3.1中，什么是仅包含某些视图的javascript文件并将其从其他视图中排除的一种巧妙方法？

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 %>

Answer 2

在您的特定html.erb文件中添加以下行

<%= javascript_include_tag "name_of_js_file" %>
