Boost JS Carousel

A style-free and accessible carousel plugin for jQuery and Boost JS. While other plugins style and arrange your carousel for you, this plugin only handles the functionality, leaving the layout and styling up to you.

Installation

Install with npm:

npm install boost-js-carousel

Install in browser:

<script src="https://cdn.rawgit.com/marksmccann/boost-js-carousel/v0.2.0/dist/carousel.min.js"></script>

Usage

Create Plugin

var boost = require('boost-js');
// var boost = $.fn.boost; (browser install)

var carousel = require('boost-js-carousel');
// var carousel = $.fn.boost.carousel; (browser install)

$.fn.carousel = boost( carousel.plugin, carousel.defaults );

Markup Structure

<ol id="carousel">
    <li>Slide 1</li>
    <li>Slide 2</li>
    <li>Slide 3</li>
</ol>
<a href="#carousel" data-role="next">Next</a>
<a href="#carousel" data-role="prev">Previous</a>
<ol data-bind="#carousel" data-role="nav">
    <li>1</li>
    <li>2</li>
    <li>3</li>
</ol>

Note: data-bind and href are used to link the element to the instance, data-role is used to define the element's role in that instance. See Boost JS for more details.
