Unobtrusive scripting adapter for jQuery

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 to:

  • force confirmation dialogs for various actions;
  • make non-GET requests from hyperlinks;
  • make forms or hyperlinks submit data asynchronously with Ajax;
  • have submit buttons become automatically disabled on form submit to prevent double-clicking.

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

Full documentation is on the wiki, including the list of published Ajax events.

Requirements

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

Installation

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

gem 'jquery-rails', '~> 2.1'

And run:

$ bundle install

This next step depends on your version of Rails.

a. For Rails 3.1, add these lines to the top of your app/assets/javascripts/application.js file:

//= require jquery
//= require jquery_ujs

b. For Rails 3.0, run this command:

Be sure to get rid of the rails.js file if it exists, and instead use the new jquery_ujs.js file that gets copied to the public directory. Choose to overwrite jquery_ujs.js if prompted.

$ rails generate jquery:install

c. For Rails 2.x and for manual installation follow this wiki .
