Answer 5

Just download a copy of jQuery from here: http://code.jquery.com/jquery-1.6.2.js

Then copy the jquery-1.6.2.js file to your <> / public / javascripts folder .

Then, in your application.html.erb file in your layout, include the jquery file before including the application.js file, as shown below:

<%= javascript_include_tag 'jquery-1.6.2', 'application' %>

Then you are good to go.
