jQuery UI for the Rails 3.1+ asset pipeline

README.md

jquery-ui-rails

Build Status Dependency Status

This gem packages the jQuery UI assets (JavaScripts, stylesheets, and images) for the Rails asset pipeline, so you never have to download a custom package through the web interface again.

See VERSIONS.md to see which versions of jquery-ui-rails bundle which versions of jQuery UI.

Also check out the jquery-ui-sass-rails gem, which allows you to override theme variables with Sass.

Note: As of version 4.0.5, jquery-ui-rails has dropped its unused dependency on the jquery-rails gem. If you get an error "couldn't find file 'jquery'", you may need to explicitly add gem 'jquery-rails' to your Gemfile.

Usage

In your Gemfile, add:

gem 'jquery-ui-rails'

Require Everything

To require all jQuery UI modules, add the following to your application.js:

//= require jquery.ui.all

Also add the jQuery UI CSS to your application.css:

/*
 *= require jquery.ui.all
 */

All images required by jQuery UI are automatically served through the asset pipeline, so you are good to go! For example, this code will add a datepicker:

$(function() {
  $('.datepicker').datepicker();
});

Require Specific Modules

The jQuery UI code weighs 51KB (minified + gzipped) and takes a while to execute, so for production apps it's recommended to only include the modules that your application actually uses. Dependencies are automatically resolved. Simply pick one or more modules from the asset list below.

For example, if you only need the datepicker module, add this to your application.js:

//= require jquery.ui.datepicker

In your application.css, require the corresponding CSS module:

/*
 *= require jquery.ui.datepicker
 */

JavaScript Assets

UI Core

//= require jquery.ui.core
//= require jquery.ui.widget
//= require jquery.ui.mouse
//= require jquery.ui.position

You usually do not need to require these directly, as they are pulled in by the other JavaScript modules as needed.

Interactions

//= require jquery.ui.draggable
//= require jquery.ui.droppable
//= require jquery.ui.resizable
//= require jquery.ui.selectable
//= require jquery.ui.sortable

For jquery.ui.resizable and jquery.ui.selectable, remember to require their matching CSS files in your application.css as well.

Widgets

//= require jquery.ui.accordion
//= require jquery.ui.autocomplete
//= require jquery.ui.button
//= require jquery.ui.datepicker
//= require jquery.ui.dialog
//= require jquery.ui.menu
//= require jquery.ui.progressbar
//= require jquery.ui.slider
//= require jquery.ui.spinner
//= require jquery.ui.tabs
//= require jquery.ui.tooltip

For all of these, remember to require their matching CSS files in your application.css as well.

I18n

Datepicker has optional i18n modules for non-US locales, named jquery.ui.datepicker-xx[-YY] (list), for example:

//= require jquery.ui.datepicker
//= require jquery.ui.datepicker-pt-BR

Note that you still need to include the main datepicker module. It is not required automatically for performance reasons.

Effects

//= require jquery.ui.effect.all
//= require jquery.ui.effect
//= require jquery.ui.effect-blind
//= require jquery.ui.effect-bounce
//= require jquery.ui.effect-clip
//= require jquery.ui.effect-drop
//= require jquery.ui.effect-explode
//= require jquery.ui.effect-fade
//= require jquery.ui.effect-fold
//= require jquery.ui.effect-highlight
//= require jquery.ui.effect-pulsate
//= require jquery.ui.effect-scale
//= require jquery.ui.effect-shake
//= require jquery.ui.effect-slide
//= require jquery.ui.effect-transfer

Stylesheet Assets

UI Core

/*
 *= require jquery.ui.core
 *= require jquery.ui.theme
 */

You might want to require these if you do not use any of the following modules, but still want jQuery UI's basic theming CSS. Otherwise they are automatically pulled in as dependencies.

Interactions

/*
 *= require jquery.ui.resizable
 *= require jquery.ui.selectable
 */

Widgets

/*
 *= require jquery.ui.accordion
 *= require jquery.ui.autocomplete
 *= require jquery.ui.button
 *= require jquery.ui.datepicker
 *= require jquery.ui.dialog
 *= require jquery.ui.menu
 *= require jquery.ui.progressbar
 *= require jquery.ui.slider
 *= require jquery.ui.spinner
 *= require jquery.ui.tabs
 *= require jquery.ui.tooltip
 */

Setup

The jquery-ui-rails gem should work in Ruby 1.8.7 apps. To run the rake tasks, you need Ruby 1.9 however.

git clone git://github.com/joliss/jquery-ui-rails.git
cd jquery-ui-rails
git submodule update --init
bundle install
bundle exec rake # rebuild assets

Most of the code lives in the Rakefile. Pull requests are more than welcome!

Hacking jQuery UI

The jquery-ui-rails repository is contributor-friendly and has a git submodule containing the official jquery-ui repo. This way it's easy to hack the jQuery UI code:

cd jquery-ui
git checkout master  # or 1-8-stable
... hack-hack-hack ...
bundle exec rake  # rebuild assets based on your changes

Assuming your app's Gemfile points at your jquery-ui-rails checkout (gem 'jquery-ui-rails', :path => '~/path/to/jquery-ui-rails'), all you need to do now is refresh your browser, and your changes to jQuery UI are live in your Rails application.

You can send pull requests to the jquery-ui GitHub project straight out of your submodule. See also their Getting Involved guide.

Testing

As a smoke test, a testapp application is available in the repository, which displays a check mark and a datepicker to make sure the assets load correctly:

cd testapp
bundle install
rails server

Now point your browser at http://localhost:3000/.

Limitations

  • Only the base theme (Smoothness) is included. Once it becomes possible to generate all theme files from the jQuery UI sources, we can package all the other themes in the ThemeRoller gallery.

    Perhaps we can also add helper tasks to help developers generate assets for their own custom themes or for third-party themes (like Selene).

    If you still want a different theme right now, you could probably download a custom theme and require the theme CSS after requiring any other jQuery UI CSS files you need, making sure to serve up the theme images correctly. (This is arguably cumbersome, not officially supported by this gem, and adds 1 KB overhead as both the base theme and the custom theme are served up.)

  • The jquery.ui.all.js file is named jquery-ui.js in the official distribution. We should follow their naming. But jquery-rails provides a jquery-ui.js asset as well, so until that is removed from the jquery-rails gem (see issue #46), we cannot distribute jquery-ui.js without risking conflicts.

    To reduce confusion, as long as there is no jquery-ui.js, we also do not distribute the official jquery-ui-i18n.js and jquery-ui.css. The latter is available as jquery.ui.all.css however.

Something went wrong with that request. Please try again.
