Add RJS, Prototype, and Scriptaculous helpers to Rails 3.1+ apps
branch: master

prototype-rails provides Prototype, Scriptaculous, and RJS on Rails 3.1 and later.

Prototype and Scriptaculous are pulled in by the asset pipeline, so you don't need to copy the source files into your app. You may reference them in your s app/assets/javascripts/application.js:

//= require prototype
//= require prototype_ujs
//= require effects
//= require dragdrop
//= require controls

prototype-rails supports RJS debugging. RJS responses are wrapped to catch exceptions, alert() them, and re-raise the exception. Debugging is disabled by default. To enable in development, set config.action_view.debug_rjs = true in config/environments/development.rb.

Support for Rails 4.1 and above

Unfortunately, due to limited manpower and resources, the Rails core team has not been able to confirm if this gem currently works with Rails 4.1 and above. If you have found any problems while upgrading your application, please report them at the issue tracker, or better yet, submit patches by sending a pull request.

In any case, this gem will NOT be officially supported on Rails 5.0 and above.

Something went wrong with that request. Please try again.
