Features

p.s. All the plugins optionally supported are MIT licensed, so as safe to use as the Coverflow plugin itself.

Download & Install

Install with bower using bower install coverflow.

jQuery v1.8.0 or higher required. jQuery v1.7.x also works, but without the ability to click on covers to select.

jQueryUI v1.9.0 or higher required.

Current version: https://github.com/vanderlee/coverflow/archive/master.zip

Sourcecode on Github: https://github.com/vanderlee/coverflow

jQueryUI custom build

If you download a custom build of jQueryUI, you need these components:

Quick start

Here's a short code fragment, demonstrating how to use coverflow at it's most basic level.

There are many more options to tailor it to your needs.

<div class="coverflow">
    <div class="cover">A</div>
    <div class="cover">B</div>
    ...
    <div class="cover">Y</div>
    <div class="cover">Z</div>
</div>

<script>
    $(function() {
        $('.coverflow').coverflow();
    });
</script>

Documentation

.coverflow(options)

Create one or more coverflows or access an existing coverflow.

Coverflow uses the concepts of "selected", "inner" and "outer" covers. There is exactly one selected cover; the one in the middle that is visible as the current (or "selected") cover. The inner cover are the ones closest to the selected cover on either side. Outer covers are the ones at the very edges of the visible field. There may be covers beyond the outer covers, but they will not be visible.

Focus

Coverflow is focussable. If you do not specify an explicit tabIndex attribute for the Coverflow element, one will be assigned with value -1, meaning it can be focussed using the mouse, but not by pressing the [tab] key.

You can optionally set the autofocus attribute on the element, and Coverflow will detect it and focus itself on page load.

Options

density (function, default: 1)

@todo

duration (integer/string, default: "normal")

The speed of animation. Use one of the standard constants "slow", "normal", "fast" or an integer for time in milliseconds.

easing (string, default: undefined)

Define an easing method for scrolling. If none is specified, "swing" easing is used by default.

enableKeyboard (boolean, default: "both")

By default, Coverflow catches keyboard events both when hovering over it or when it has focus. Available options are "focus", "hover", "both" and "focus". You can also use boolean true or false to completely enable or disable keyboard. Can be enabled/disabled using the option and options method.

If you use multiple coverflow components, you should use either "focus" or "hover", otherwise the keyboard will affect multiple Coverflows at once.

enableClick (boolean, default: true)

Set to false to disable mouse button (and touch tap) interaction. Can be enabled/disabled using the option and options method.

enableWheel (boolean, default: true)

Set to false to disable mouse wheel interaction. Can be enabled/disabled using the option and options method.

index (string, integer: 0)

The initial selected index.

innerAngle (float, integer: -75)

An angle, in degrees, of the inner covers. Negative values indicate the covers are turned inwards (towards the center). Positive values indicate the covers will be turned outwards.

innerCss (object, default: undefined)

A plain object containing CSS properties of the inner covers. Leave undefined if you don't need any CSS changes. You can specify all (and only) the CSS properties supported by jQuery/jQueryUI.

innerOffset (float, default: 100/3)

@todo

innerScale (float, integer: 0.75)

@todo

outerAngle (float, integer: -30)

An angle, in degrees, of the outer covers. Negative values indicate the covers are turned inwards (towards the center). Positive values indicate the covers will be turned outwards.

outerCss (object, default: undefined)

A plain object containing CSS properties of the outer covers. Leave undefined if you don't need any CSS changes. You can specify all (and only) the CSS properties supported by jQuery/jQueryUI.

outerScale (float, integer: 0.25)

@todo

selectedCss (object, default: undefined)

A plain object containing CSS properties of the selected cover. Leave undefined if you don't need any CSS changes. You can specify all (and only) the CSS properties supported by jQuery/jQueryUI.

visible (string/float, default: "density")

@todo

width (integer, default: undefined)

@todo

Methods

cover

Get the currently selected cover as a jQuery object.

index

Get or set the current index. If no value is provided, the current index is returned. Otherwise, the index will be set to the provided value.

refresh

Redraw the covers. You shouldn't ever need to do this unless you are adding or removing covers or changing the covers yourself.

Events

before

Triggered just before moving the coverflow to a new index.

Callback: function(event, cover, index)

change

Triggered whenever the current cover index changes. This includes initially and for each cover passed by when skipping past multiple covers. Change triggers as soon as the cover is on front; this may be before or after it's animation is completed (but only once!).

Callback: function(event, cover, index)

confirm

Triggered when the user clicks on the current cover.

Callback: function(event, cover, index)

event.originalEvent.target contains the DOM element that was clicked to trigger the confirm event.

select

Triggered whenever a cover is selected. This includes initially. In contrast to the change event, select only triggers once after the requested cover position has been reached.

Callback: function(event, cover, index)

animateStep

Triggered for every animation frame. Use this event to customize how the animation looks if the default options provide insufficient control.

Callback: function(event, cover, offset, isVisible, isMiddle, sin, cos)

animateComplete

Triggered after the animation has stopped. A final animateStep will be triggered after animation as well, so you don't need to use the animateComplete event for normal animation frames.

Callback: function(event, cover, offset, isVisible, isMiddle, sin, cos)

Extensions/dependencies

Coverflow is designed to take advantage of a number of separate Javascript libraries to supply additional features. The download comes with these files included. If you deploy your code, you may wish to use or exclude these files.

Interpolate

https://github.com/vanderlee/interpolate

Interpolate is a library for smoothly interpolating CSS by taking advantage of the builtin jQuery and jQueryUI features. jQuery/jQueryUI offer support to smoothly animate transitions between two states of a large number of CSS rules but does not provide an interface to get a single "frame". Interpolate provides that interface.

If you want to use Coverflow's innerCss and outerCss features, including Interpolate will ensure the animations will be smooth.

TouchSwipe-Jquery-Plugin

https://github.com/mattbryson/TouchSwipe-Jquery-Plugin

TouchSwipe provides support for touch device input, like swiping the coverflow sideways. If you include this plug-in (or any plugin providing a compatible .swipe() implementation), Coverflow will detect it and support swiping.

Relection.js

http://www.digitalia.be/software/reflectionjs-for-jquery/

The Reflection.js jQuery plugin provides controlable image reflections underneath the images. Though Coverflow neither detects nor interacts with this script, Coverflow is designed to work smoothly with this plugin without any additional code.
