How to use jQuery instead of Prototype in a Rails 3 application?

Question

I would like to use jQuery instead of Prototype in my Rails 3 application.

What is the \"official\" Rails 3 way to do this?

Answer 1

First you need to install the gem, by adding this line to the Gemfile:

gem 'jquery-rails', '>= 0.2.6'

(and run bundle install) Then you need to go to the public/javascript folder and you need to replace the rails.js file by the one from: http://github.com/rails/jquery-ujs.

The proper way of doing this is to do:

rails generate jquery:install

or if you want to include jQuery UI:

rails generate jquery:install --ui

From the Github page:

This will remove the Prototype.js library from Rails, add latest jQuery library and fetch the adapter. Be sure to choose to overwrite the "rails.js" file.
