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
- jQuery 1.8.x or higher;
- 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. However, this shouldn't create any issues for web browsers or other user agents.
Installation using the jquery-rails gem
For automated installation in Rails, use the "jquery-rails" gem. Place this in your Gemfile:
gem 'jquery-rails'
And run:
$ bundle install
Require both jquery
and jquery_ujs
into your application.js manifest.
//= require jquery
//= require jquery_ujs
Installation using npm.
Run npm install --save jquery-ujs
to install the jquery-ujs package.
Installation using Rails and Webpacker
If you're using webpacker (introduced in Rails 5.1) to manage JavaScript assets, then you can add the jquery-ujs npm package to your project using the yarn CLI.
$ yarn add jquery-ujs
Then, from any of your included files (e.g. app/javascript/packs/application.js
, or from a JavaScript file imported by such a pack), you need only import the package for jquery-ujs to be initialized:
import {} from 'jquery-ujs'
Installation using Bower
Run bower install jquery-ujs --save
to install the jquery-ujs package.
Usage
Require both jquery
and jquery-ujs
into your application.js manifest.
//= require jquery
//= require jquery-ujs
