Hey Venkat,

Did you added

add jquery.js into your app/assets/javascripts folder.

add these lines into layout and try.
<%= javascript_include_tag ‘jquery.js’,‘application.js’ %>

Cheers,
Sai

If he is using Rails 3.1 it’s not necessary to manually include the
jQuery
library using a tag. It’s also not necessary to manually
include
application.js like he is doing.

It’s better to use the asset pipeline.

Make sure your Gemfile contains the following line:

gem ‘jquery-rails’

Also make sure your app/assets/application.js includes the following
line:

//= require jquery

And then when you use the following helper, jquery will be automagically
included:

stylesheet_link_tag “application”

Check the guide on the Asset Pipeline for lots more information:

Thanks,
Sai
