Ruby on Rails unobtrusive scripting adapter.
========================================

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][data] to your HTML markup. In Rails, they are added by the framework's template helpers.

Requirements
------------

- HTML5 doctype (optional).

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.

Installation using npm
------------

Run `npm install rails-ujs --save` to install the rails-ujs package.

Installation using Yarn
------------

Run `yarn add rails-ujs` to install the rails-ujs package.

Usage
------------

Require `rails-ujs` into your application.js manifest.

```javascript
//= require rails-ujs
```

How to run tests
------------

Run `bundle exec rake ujs:server` first, and then run the web tests by visiting [[http://localhost:4567]] in your browser.
