Ideal Image Slider

The aim behind the Ideal Image Slider is to create a slider which has just the right amount of features, with no bloat and be easy to extend so that more features can be added as "extensions". Here are the ideals and core features I wanted to include:

  • HTML5 (SEO optimised)
  • CSS3 transitions (a few simple transitions like slide/fade)
  • Left/Right navigation (including touch/swipe support)
  • Responsive
  • HiDPI (retina) support
  • ARIA support
  • Extremely simple to setup (no dependencies)
  • Very extensible
  • Uses progressive enhancement
  • Open source (goes without saying)

And, as an example, here are some features that should not be in the core and could be optional extensions:

  • Themes or skins
  • More transitions
  • Bullet navigation
  • Thumbnail navigation
  • Full screen slider
  • Video/Audio support
  • etc...

Extensions

Requirements

  • None

Ideal Image Slider is written in vanilla JS and has no dependancies.

Getting Started

To install the slider you can either manually download this repository or you can use Bower and run the following command:

bower install ideal-image-slider --save 

Next you need to include the CSS file in the <head> section of your HTML and you need to include the script before the </body> tag in your HTML. Note you can optionally include a theme CSS file in the <head> too.

<html> <head> 	... 	<link rel="stylesheet" href="/path/to/ideal-image-slider.css"> 	<link rel="stylesheet" href="/path/to/themes/default/default.css"> 	... </head> <body> 	... 	<script src="/path/to/ideal-image-slider.js"></script> </body> </html>

Next you need to set up your slider HTML where you want it to appear in your page. It should look something like this:

<div id="slider"> 	<img src="img/1.jpg" alt="Minimum required attributes"> 	<img data-src="img/2.jpg" src="" alt="Use data-src for on-demand loading"> 	<img data-src="img/3.jpg" data-src-2x="img/[email protected]" src="" alt="Use data-src-2x for HiDPI devices"> 	<a href="http://example.com"><img data-src="img/4.jpg" src="" alt="Links work too"></a> 	... </div>

There a few things to note about the structure of the images in your slider:

  • This is an image slider, so only images are supported. Any other content will be removed.
  • You can use the data-src attribute to load your images "on-demand" (i.e. images are not loaded until they are required).
  • The first image should not use data-src so it is loaded if no JS is detected.
  • If you specify a data-src-2x image, it will be used on devices that support HiDPI (such as Apple's retina devices).

Finally you can create your slider by using the following Javascript:

new IdealImageSlider.Slider('#slider');

If you want to tweak the settings or use the slider API it would look more like:

var slider = new IdealImageSlider.Slider({ 	selector: '#slider', 	height: 400, // Required but can be set by CSS 	interval: 4000 }); slider.start();

Note: If you don't pass a height to the Javascript constructor you must set it in your CSS.

Settings

Setting Default Value Description
selector '' CSS selector for the slider
height 'auto' Height of the slider. Can be 'auto' (height changes depending on the height of the slide), a fixed px value (e.g. 400) or an aspect ratio (e.g. '16:9')
initialHeight 400 If height is 'auto' or an aspect ratio this is the height of the slider while the first image is loading
maxHeight null If height is 'auto' or an aspect ratio this is an optional max height in px for the slider (e.g. 800)
interval 4000 Time (in ms) to wait before changing to the next slide
transitionDuration 700 Duration (in ms) of animated transition
effect 'slide' Transition effect (slide/fade by default)
disableNav false Toggle the previous/next navigation (also disables touch and keyboard navigation)
keyboardNav true Toggle keyboard navigation
previousNavSelector '' Selector for custom previous nav element
nextNavSelector '' Selector for custom next nav element
classes {...} List of classes to be used by slider. Probably shouldn't be changed

Events

Event callback functions can be passed in with the settings. For example:

new IdealImageSlider.Slider({ 	selector: '#slider', 	onStart: function(){ 		console.log('onStart'); 	} });
Event Description
onInit Callback that fires when slider and first image have loaded
onStart Callback that fires when slider has started playing
onStop Callback that fires when slider has stopped playing
onDestroy Callback that fires when slider is destroyed
beforeChange Callback that fires before a slide has changed
afterChange Callback that fires after a slide has changed

API

To use the API methods you must store the slider object. For example:

var slider = new IdealImageSlider.Slider('#slider'); slider.start();
Method Description
start() Start the slider. Note the slider will automatically be stopped when navigation is used
stop() Stop the slider
previousSlide() Change to the previous slide
nextSlide() Change to the next slide
gotoSlide(index) Change to a specific slide (1 indexed)
destroy() Destroy the slider
get(attribute) Get an attribute value (attributes are mostly used internally)
set(attribute, value) Set an attribute. Can be useful for storing custom data
