+# Carousel
+
+
+
+A responsive image carousel.
+
+## Introduction
+The Material Design Lite Ext (MDLEXT) Carousel, commonly also referred to as “slide shows” or “sliders”, is a component
+for cycling through a series of images. The carousel is defined and enclosed by a container element and
+distributes images horizontally, with repect to the available container size. Images outside the container viewport slides
+into view, triggerd by a user action or by running an animation loop (rAF).
+
+This component does not attempt in any way to resemble a three-dimensional image carousel that is used to show slides
+from a projector. The component is perceived more as a slider, but the terms slider and carousel, are often used
+interchangeably.
+
+### Features:
+* Navigate carousel using keyboard (arrow keys, tab, pgup, pgdown, home, end), mouse drag, touch events, or by sending custom events to the carousel (first, scroll-prev, prev, next, scroll-next, last, play, pause)
+* Select a particular image using enter or space key, or by clicking an image
+* Cycle images at a given interval - a slideshow
+* Set slideshow interval via a data attribute or as a part of the play custom event
+* Stop slideshow via custom event (pause) or by a user interaction, e.g clicking an image
+* User interactions via keyboard, mouse or touch events may be blocked, if configured
+* Start slideshow at component initialization using a data attribute
+* The carousel emits custom events reflecting a user action. E.g. clicking an image will emit a 'select' event with a detail object holding a reference to the selected image.
+
+### Limitations:
+* The carousel should pause any running animation on window.bur or tab.blur - not implemented
+* The carousel should pause any running animation when the carousel is not in window viewport - not implemented
+* Only horizontal layout in first release
+
+
+### To include a MDLEXT **carousel** component:
+ 1. Code a block element, e.g. a `<div>` element, to hold dimensions of the carousel.
+```html
+<div style="height: 200px; width: 100%;">
+</div>
+```
+
+ 2. Code a `<ul>` element with `class="mdlext-carousel mdlext-js-carousel"` to hold the carousel.
+```html
+<div style="height: 200px; width: 100%;">
+ <ul class="mdlext-carousel mdlext-js-carousel">
+ <ul>
+</div>
+```
+
+ 3. Code a `<li>` element with `class="mdlext-carousel__slide"` to hold an individual image (thumbnail).
+```html
+<div style="height: 200px; width: 100%;">
+ <ul class="mdlext-carousel mdlext-js-carousel">
+ <li class="mdlext-carousel__slide">
+ <li>
+ <ul>
+</div>
+```
+
+ 4. Code a `<figure>` element to hold the image and the image title.
+```html
+<div style="height: 200px; width: 100%;">
+ <ul class="mdlext-carousel mdlext-js-carousel">
+ <li class="mdlext-carousel__slide">
+ <figure>
+ </figure>
+ <li>
+ <ul>
+</div>
+```
+
+ 5. Inside the `<figure>` element add an `<img>` element with reference to the thumbnail image to be shown. Optionally add a `<figcaption>` element to hold the image title.
+```html
+<div style="height: 200px; width: 100%;">
+ <ul class="mdlext-carousel mdlext-js-carousel">
+ <li class="mdlext-carousel__slide">
+ <figure>
+ <img src="_D802591.jpg" title="Whooper swans in flight"/>
+ <figcaption>_D802591.jpg</figcaption>
+ </figure>
+ <li>
+ <ul>
+</div>
+```
+
+ 6. Repeat steps 3..5 for each slide required.
+
+### Examples
+* See: [snippets/carousel.html](./snippets/carousel.html)
+* Or try out the [live demo](http://leifoolsen.github.io/mdl-ext/demo/carousel.html)
+
+## Interactions
+
+### Keyboard interaction
+The carousel interacts with the following keyboard keys.
+
+* `Tab` - When focus is on a slide, pressing the `Tab` key moves focus in the following manner:
+ * If there is a next slide, focus moves to the next slide.
+ * If focus is on the last slide, focus moves to the first focusable element outside the carousel component.
+* `Shift+Tab` - Generally the reverse of `Tab`.
+* `Left arrow` - Moves focus to the previous slide. If the current slide is the first slide, focus stays on that slide.
+* `Right arrow` - Moves focus to the next slide. If the current slide is the last slide, focus stays on that slide.
+* `Up arrow` - behaves the same as left arrow.
+* `Down arrow` - behaves the same as right arrow.
+* `End` - When focus is on a slide, an `End` key press moves focus to the last slide.
+* `Home` - When focus is on a slide, a `Home` key press moves focus to the first slide.
+* `Enter/Space` - When focus is on a slide, pressing `Enter` or `Space` selects the focused slide.
+
+### Mouse / Touch interaction
+* `Drag or Swipe left` - Move slides outside container viewport into view.
+* `Drag or Swipe right` - Move slides outside container viewport into view
+
+
+## Component configuration
+The component can be configured using a `data-config` attribute. The attribute value is a JSON string with the following properties.
+
+| Property | | |
+|-----------------|----|----|
+| `interactive` | if `true`, the user can use keyboard or mouse to navigate the slides | default: `true` |
+| `autostart` | if `true`, the slideshow starts immediately after component initialization | default: `false` |
+| `type` | animation type, `'slide'`, advances one slide, `'scroll'`, moves next sequence of slides into view | default `'slide'` |
+| `interval` | animation interval, in milliseconds | default `1000` |
+
+
+The `data-config` attribute must be a valid JSON string. You can use single or double quotes for the JSON properties.
+
+Example 1, single quotes in JSON config string:
+```html
+<ul class="mdlext-carousel mdlext-js-carousel mdl-js-ripple-effect mdl-js-ripple-effect--ignore-events"
+ data-config="{ 'interactive': true, 'autostart': false, 'type': 'slide', 'interval': 2000 }">
+ ......
+</ul>
+```
+
+Example 2, double quotes in JSON config string:
+```html
+<ul class="mdlext-carousel mdlext-js-carousel"
+ data-config='{ "interactive": false, "autostart": true, "type": "scroll", "interval": 5000 }'>
+ ......
+</ul>
+```
+
+## Events
+Interaction with the component programmatically is performed by sending events to the component, and receive responses
+from the component.
+
+### Events the component listenes to
+A client can send a `command` custom event to the carousel. The command event holds an action detail object defining
+the action to perform.
+
+```javascript
+new CustomEvent('command', { detail: { action : 'first' } });
+new CustomEvent('command', { detail: { action : 'scroll-prev' } });
+new CustomEvent('command', { detail: { action : 'prev' } });
+new CustomEvent('command', { detail: { action : 'next' } });
+new CustomEvent('command', { detail: { action : 'scroll-next' } });
+new CustomEvent('command', { detail: { action : 'last' } });
+new CustomEvent('command', { detail:
+ {
+ action : 'play',
+ interval: 3000 // Interval is optional, overrides value set by 'data-config'
+ }
+});
+new CustomEvent('command', { detail: { action : 'pause' } });
+
+// Trigger the event
+myCarousel.dispatchEvent(ev);
+```
+
+Refer to [snippets/lightbox.html](./snippets/carousel.html) for usage.
+
+### Events emitted
+When a user interacts with the component, or the component receives a `command` custom event, the component responds
+with a `select` custom event reflecting the action performed and a detail object holding the selected slide element.
+
+The `select` detail object has the following format:
+
+```javascript
+detail: {
+ command, // The command executed (`first`, `scroll-prev`, `prev`, `next`, `scroll-next`, `last`)
+ keyCode, // Key pressed, if any
+ source // The element that caused the event
+}
+```
+
+Set up a `select` listener.
+```javascript
+document.querySelector('#my-carousel').addEventListener('select', function(e) {
+ var selectedElement = e.detail.source;
+ console.log('Selected element', selectedElement);
+ var selectImage = selectedElement.querySelector('img');
+});
+
+```
+Refer to [snippets/lightbox.html](./snippets/carousel.html) for usage.
+
+
+## Public methods
+
+### `stopAnimation()`
+
+Stops animation - if any.
+
+### `upgradeSlides()`
+Upgrade slides. If you add slides to the carousel after the page has loaded, you must call `upgradeSlides` to
+notify the component about the newly inserted slides.
+
+```javascript
+myCarousel = document.querySelector('#my-carousel');
+myCarousel.MaterialExtCarousel.upgradeSlides();
+```
+
+### `getConfig()`
+Returns the `config` object.
+
+
+## Configuration options
+The MDLEXT CSS classes apply various predefined visual and behavioral enhancements to the carousel.
+The table below lists the available classes and their effects.
+
+| MDLEXT class | Effect | Remarks |
+|--------------|--------|---------|
+| `mdlext-carousel` | Defines a container as an MDLEXT carousel component | Required on `<ul>` element |
+| `mdlext-js-carousel` | Assigns basic MDL behavior to carousel | Required on `<ul>` element |
+| `mdlext-carousel__slide` | Defines a carousel slide | Required on `<li>` element |
+
+Attributes.
+
+| Attribute | Effect | Remarks |
+|-----------|--------|---------|
+| `data-config` | A JSON object defining startup configurations | |
+| `aria-selected` | The selected `mdlext-carousel__slide` element | Only one element can be selected at the same time |
+| `list` | The component add the role `list` to self | |
+| `listitem` | The component add the role `listitem` to `mdlext-carousel__slide` items | |
+
+
+## Note for single page applications
+If you use Material Design Lite in a dynamic page, e.g. a single page application, any running animations must be
+stopped before a page frament containing a carousel component is removed from the DOM. Call
+`componentHandler.downgradeElements` to stop any running animation and clean up component resources.
+In a static web application there should be no need to call `componentHandler.downgradeElements`.
+
+The following code snippet demonstrates how to properly clean up components before removing them from DOM.
+
+```javascript
+// Call 'componentHandler.downgradeElements' to clean up
+const content = document.querySelector('#content');
+const components = content.querySelectorAll('.is-upgraded');
+componentHandler.downgradeElements([...components]);
+
+// Remove elements from DOM.
+// See: http://jsperf.com/empty-an-element/16
+const removeChildElements = (element, forceReflow = true) => {
+ while (element.lastChild) {
+ element.removeChild(element.lastChild);
+ }
+ if(forceReflow) {
+ // See: http://jsperf.com/force-reflow
+ const d = element.style.display;
+ element.style.display = 'none';
+ element.style.display = d;
+ }
+}
+
+removeChildElements(content);
+```
+
+## How to use the component programmatically
+The [tests](../../test/carousel/carousel.spec.js) and the [snippets/lightbox.html](./snippets/carousel.html)
+code provides examples on how to use the component programmatically.
