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` in your application.js manifest.
```javascript
//= require rails-ujs
```
Usage with yarn
------------
When using with the Webpacker gem or your preferred JavaScript bundler, just
add the following to your main JS file and compile.
```javascript
import Rails from 'rails-ujs';
Rails.start()
```
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.
