slick-lightbox

A lightbox wrapper for Ken's amazing slick carousel. Credits go to kenwheeler for doing the hard work.

Usage

Install via bower.

bower install -S slick-lightbox

Make sure you include CSS for both slick and slick-lightbox. Example HTML:

<!DOCTYPE html>
<html>
<head>
  <title>slick lightbox</title>
  <meta name="viewport" content="width=device-width">
  <link rel="stylesheet" type="text/css" href="bower_components/slick-carousel/slick/slick.css">
  <link rel="stylesheet" type="text/css" href="bower_components/slick-carousel/slick/slick-theme.css">
  <link rel="stylesheet" type="text/css" href="styles/slick-lightbox.css">
</head>
<body>
  <div>
    <ul>
      <li><a href="http://placekitten.com/1600/1300" data-caption="Lorem ipsum 1600x1300">http://placekitten.com/1600/1300</a></li>
      <li><a href="http://placekitten.com/1630/1280" data-caption="Lorem ipsum 1630x1280">http://placekitten.com/1630/1280</a></li>
      <li><a href="http://placekitten.com/1500/1250" data-caption="Lorem ipsum 1500x1250">http://placekitten.com/1500/1250</a></li>
    </ul>
  </div>
  <script type="text/javascript" src="bower_components/jquery/dist/jquery.js"></script>
  <script type="text/javascript" src="bower_components/slick-carousel/slick/slick.min.js"></script>
  <script type="text/javascript" src="scripts/slick-lightbox.js"></script>
  <script type="text/javascript">
    $(document).ready(function(){
      $('ul').slickLightbox({
        itemSelector: '> li > a'
      });
    });
  </script>
</body>
</html>

Options

Option Type Default Description
background string rgba(0,0,0,.8) Background for the lightbox. Is used directly as a CSS background statement so that color and/or an image can be used.
closeOnEscape boolean true Should the lightbox close upon pressing ESC?
closeOnBackdropClick boolean true Should the lightbox close upon clicking on backdrop?
destroyTimeout number 500 How many ms should we wait before actually removing the lightbox from the DOM? The default is used so that a 0.5s opacity transition can take place.
itemSelector string a jQuery-like selector for the carousel-to-create items. The items should be anchors with href attribute aiming at the desired lightbox image. If that's not the case, you should specify the src option.
navigateByKeyboard boolean true Can you use keyboard arrows to navigate the carousel?
slick object {} Slick options to pass to the carousel.
caption various false Should the images be captioned? If false, no caption is created. You can pass your own function accepting the element and info attributes (e.g. function(element, info) { return $(element).doSomething(); }, with info being an { index: itemIndex, length: itemCount } object) or a string with the name of the data-attribute to be fetched (my-caption will get the value of data-my-caption attribute).
src various false How to get the image urls? If false, no src is taken as the href attribute. You can pass your own function accepting the element as an attribute (e.g. function(element) { return $(element).doSomething(); }) or a string with the name of the attribute to be fetched (src will get the value of element.src attribute).
captionPosition various 'dynamic' Where should the caption be placed? When set to 'dynamic', the caption is displayed right under the image. When 'bottom', the caption is on the bottom of the screen independent to the image size.
images various false When passed an array, slick lightbox doesn't scan the elements for image URLs and uses array's values instead.
useHistoryApi boolean false When true, opening the lightbox does a history.pushState. The plugin then listens for the popstate event to close the lightbox.
layouts object See Layouts
shouldOpen function null Given a function, checks the return value before opening. If the function returns a falsy value, the lightbox is not opened upon clicking on the items. Accepts three arguments - the slick lightbox instance as the first, the clicked element as the second and the click event as the last.
imageMaxHeight number 0.9 Maximum height of the lightbox images. Relative to the window height.
lazy boolean false Should the images be lazyloaded?
lazyPlaceholder string null Path to lazyloading placeholder. Defaults to a blank gif.

Events

Events are triggered on the source element. Example:

$(document).ready(function(){
  $('ul').slickLightbox().on({
    'show.slickLightbox': function(){ console.log('A `show.slickLightbox` event triggered.'); },1
    'shown.slickLightbox': function(){ console.log('A `shown.slickLightbox` event triggered.'); },
    'hide.slickLightbox': function(){ console.log('A `hide.slickLightbox` event triggered.'); },
    'hidden.slickLightbox': function(){ console.log('A `hidden.slickLightbox` event triggered.'); }
  });
});
Event Description
show.slickLightbox Triggered when the lightbox is opened.
shown.slickLightbox Triggered when the lightbox is opened, after the transitions took place.
hide.slickLightbox Triggered when the lightbox is closed.
hidden.slickLightbox Triggered when the lightbox is closed, after the transitions took place.

Layouts

The layout is customizable using the layouts option object.

You can access the lightbox instance through the bound element. It's assigned to .slickLightbox. Example:

$('#my-element').slickLightbox()
console.log('My slickLightbox instance:', $('#my-element')[0].slickLightbox)
// once a lightbox is opened
console.log('My slick instance:', $('#my-element')[0].slickLightbox.slick)
