# jquery-rails

jQuery! For Rails! So great.

This gem provides:

  * jQuery 1, 2 and 3
  * the jQuery UJS adapter
  * assert_select_jquery to test jQuery responses in Ruby tests

## Versions

Starting with v2.1, the jquery-rails gem follows these version guidelines
to provide more control over your app's jQuery version from your Gemfile:

```
patch version bump = updates to jquery-ujs, jquery-rails, and patch-level updates to jQuery
minor version bump = minor-level updates to jQuery
major version bump = major-level updates to jQuery and updates to Rails which may be backwards-incompatible
```

See [VERSIONS.md](VERSIONS.md) to see which versions of jquery-rails bundle which
versions of jQuery.

## Installation

The jquery and jquery-ujs files will be added to the asset pipeline and available for you to use. If they're not already in `app/assets/javascripts/application.js` by default, add these lines:

```js
//= require jquery
//= require jquery_ujs
```

If you want to use jQuery 2, you can require `jquery2` instead:

```js
//= require jquery2
//= require jquery_ujs
```

And if you want to use jQuery 3, you can require `jquery3`:

```js
//= require jquery3
//= require jquery_ujs
```

For jQuery UI, we recommend the [jquery-ui-rails](https://github.com/joliss/jquery-ui-rails) gem, as it includes the jquery-ui css and allows easier customization.

*As of v3.0, jquery-rails no longer includes jQuery UI. Use the
jquery-ui-rails gem above.*
