Better Unobtrusive JavaScript Respond (for Rails and jquery_ujs, twitter/bootstrap modal.js)

SrBuj comes to cure a common illness in a life of every Rails developer (maybe other kind too):

Every time, we end up with a lot of code, ugly code, messy code or at best with an old and known .js.rb file with the same 4 lines... Well enough it's enough! This is the cure...and comes with a simple treatment too!


  1. bundle the gem
  2. required in your manifest
  3. add the 'magic data attributes' to the element
  4. enjoy the js-less ! :-)

This unobtrusive scripting support file is developed for the Ruby on Rails framework, but is not strictly tied to any specific backend. You can drop this into any application.

These features are achieved by adding certain ["data" attributes][data] to your HTML markup. In Rails, they are added by the framework's template helpers.


If you don't use HTML5, adding "data" attributes to your HTML4 or XHTML pages might make them fail [W3C markup validation][validator]. However, this shouldn't create any issues for web browsers or other user agents.


For automated installation in Rails, use the "jquery-rails" gem. Place this in your Gemfile:

  gem 'SrBuj'

And run:

$ bundle install

use the generator:

$ bundle exec rails g sr_buj:install

or the manual way:

For Rails 3.1 and higher, add //= require SrBuj in your app/assets/javascripts/application.js file like this:

//= require jquery
//= require jquery_ujs
//= require SrBuj

and add *= require SrBuj in your app/assets/stylesheets/application.css file:

 *= require_self
 *= require SrBuj
 *= require_tree .

Use and Options

You can use it with any html element available. (links forms tables divs...Anything).



in your view (example with a link and haml)

 = link_to 'add Element', elements_path, remote: true, data: {target: 'partial-id', modal: true}


in your controller

  def new
    render partial: 'new', content_type: 'text/html' #=> the content_type stands for telling the js request that everything ends up

that's it.
