You can push images loaded via ajax to the lightbox
Small in Size (< 10Kb, < 3Kb gzipped)
CSS3-Animations & controls, however, loading GIFs and arrow images can be used
Licensed under MIT, code is free for commercial & personal use. However, it would be great if you send me an link of your websites using my lightbox so I can see it live in action and post some real-word examples here. I am also happy about backlinks & github-stars :) The pictures included are NOT free to use! Please contact me first if you want to use the them!
Developing tools like this lightbox takes a lot of time. If you like my lightbox and want to support me, buy me a beer via the paypal-donate button on my site :) Thanks!
Do not forget to add those lines inside your <head></head> if you want to support IE8:
<script src="lightbox.min.js" type="text/javascript"></script>
<script>
var lightbox = new Lightbox();
lightbox.load();
</script>
You just need to add the attribute data-jslghtbx to all the images or elements you want to show in the lightbox:
<img class="jslghtbx-thmb" src="img/lightbox/1.jpg" alt="" data-jslghtbx>
<a href="img/lightbox/1.jpg" data-jslghtbx="img/lightbox/1.jpg">Opens lightbox with a no-js fallback link</a>
Note: The CSS-class jslghtbx-thmb is optional. You can use your own styling if you want.
You can pass a link of a different image via the data-jslghtbx attribute, which then will be loaded on click. Use this if you want to use small sized pictures for the thumbnails to reduce traffic:
You can also dynamically push images to groups, this is usefull if you load images via ajax. See the lightbox.thumbnails attribute for an example.
If you want to group images to structure your content, use the data-jslghtbx-group attribute. You can have multiple groups on one page. This is also helpful when you dont want to use thumbnails, just hide the thumbnails via CSS:
The default control-arrows will be loaded when using groups. You can also use your own control-buttons by providing an ID via the options. For more detail look into the options section below.
If you want to use captions add the data-jslghtbx-caption attribute. You can also pass HTML:
<img class="jslghtbx-thmb" src="img/lightbox/2.jpg" alt="" data-jslghtbx data-jslghtbx-caption="This is my <a href='http://abc.de'>caption.</a>">
CSS Animations
When the lightbox is opened first, the image inside gets the class jslghtbx-animate-init. This is useful if you want to animate opacity.
If you are showing multiple images inside the box via the group-param, the classes jslghtbx-animating-next and jslghtbx-animating-prev are added and removed, each for half of the durationtime given by the option animation (defaults to 400 milliseconds).
The box receives the class jslghtbx-active when opened, and the wrapper gets jslghtbx-wrapper-active when all calculations are done. Feel free to edit those styles.
Options
{responsive: bool}
Default: true
If set to true, the image will be resized according to the viewport on resize-events.
{preload: bool}
Default: true
If set to true, the previous and the next image of the currently shown image will be preloaded if not already in cache.
{loadingAnimation: string || number || boolean}
Default: 200
If set to true, an animation will be rendered until the image is loaded. Alternatively you can pass milliseconds as number, which defines the interval the span-elements inside the jslghtbx-loading-animation-container get the class jslghtbx-active (the default interval is 200ms). You can use this to apply your own styling via CSS. The animation is using CSS3, so it will not work in IE8/9. You can also pass a link to an GIF-image, which then replaces the animation. This is disabled for IE8 due to bugs with transparent backgrounds and performance issues. If set to false, no animation is shown.
Note: The animations get an 500ms delay until they start, so they won`t pop up on fast connections. Also, you should check for CSS3-support and set the animation-option accordingly.
{animElCount: number}
Default: 4
This sets the number of animated span tags which are appended to the jslghtbx-loading-animation container. Must be higher than 1.
{carousel: bool}
Default: true
If set to true, you can infinitely loop through all the images by clicking the next/prev button or calling the next() / prev()-functions.
{captions: bool}
Default: true
If set to true, the caption text inside the data-jslghtbx-caption attribute will be shown. Note that the text may not be visible completely if it is very long. Feel free to style the caption class .jslghtbx-caption to your needs.
{closeOnClick: bool}
Default: true
If set to true, the lightbox will close on click anywhere inside the viewport, not just by clicking on the close-button (except when clicking on the image. see nextOnClick for this).
Note: May not work in IE8.
{nextOnClick: bool || function(image)}
Default: true
If set to true, a click on the current image shows the next image. Alternatively you can pass your own function here which will receive the image which is currently displayed including original width and height as param.
{hideOverflow: bool}
Default: true
Hides scrollbars when lightbox is opened.
{hideCloseBtn: bool}
Default: false
Hides the closebutton inside the lightbox.
{dimensions: bool}
Default: true
Images will be resized to a maximum of the original dimensions. If set to false, images are always scaled to fullscreen.
{controls: bool}
Default: true
Show or hide the default next- & prev-buttons.
{keyControls: bool}
Default: true
Use right and left keys on keyboard to navigate through gallery and escape key to close the box.
{nextImg: 'path/to/image'}
Here you can pass the path to an alternative next-button image. By default the arrows are rendered via CSS. If you want to use images make sure to apply custom styling for smaller viewports via the CSS-Class jslghtbx-next.
{prevImg: 'path/to/image'}
Here you can pass the path to an alternative prev-button image. By default the arrows are rendered via CSS. If you want to use images make sure to apply custom styling for smaller viewports via the CSS-Class jslghtbx-prev.
{boxId: 'elementId'}
Here you can pass an ID if you want to use your own box-element. Images will be appended to that element then. The element will receive a class "jslghtbx-active" when opened, so style this class properly (you need at least to remove visibility by default and add it on active). If you want it to look like the default-box, just add the class "jslghtbx" to the box-element.
{animation: number | bool}
Default: 400
This options defines wether the next/prev-switch should be animated. If you pass an integer-value, it defines the milliseconds for the animation. Passing false disables the animation. Note that all animations are done via CSS3-transitions, so if you want to alter them you have to do it via the CSS-file.
{maxImgSize: float}
Default: 0.8
This is the modifier which is used to reduce the images size when it's full size won't fit in the viewport. Maximum value is 1 for 100%.
Callbacks
{onopen: function(image)}
Function that is executed when the lightbox is opened. Receives the image which is currently displayed including original width and height as param.
{onclose: function(image)}
Function that is executed when the lightbox is closed. Receives the last image which was displayed including original width and height as param.
{onresize: function(image)}
Function that is executed when the lightbox is resized. Receives the image which is currently displayed including original width and height as param.
{onload: function(event)}
Function that is executed once the current image is loaded. The callback receives an event which is "prev" if the prev button was clicked, "next" if the next button was clicked or false for all other ways of opening the lightbox.
{onloaderror: function(event)}
Function that is executed when the current image fails to load. You can add your handlers here to display a warning or call other functions. The callback receives an full image-error-event which has a property _happenedWhile. That property is "prev" if the prev button was clicked, "next" if the next button was clicked or false for all other ways of opening the lightbox. This allows you to handle errors. For example you can just show the next or previous picture if the current one is not available:
Function that is executed once the current image is clicked. Receives the image which is currently displayed including original width and height as param.
Attributes
lightbox.thumbnails
Type: Array
Array holding all thumbnail elements. If you want to dynamically load and push pictures to an existing group be sure to set a groupname on the element via the data-jslghtbx-group attribute. If you want to show just one dynamic loaded picture you should use the open() method. Don't forget to set the data-jslghtbx-index attribute as unique identifier!
Example:
var img = new Image()
img.src = 'img/lightbox/9-small.jpg'
img.setAttribute('data-jslghtbx-group','mygroup1')
img.setAttribute('data-jslghtbx-index', lightbox.thumbnails.length)
lightbox.thumbnails.push(img)
Methods
lightbox.load(options)
The init-function. Here you can pass your option-object. Has to be called once on the box-object. If you dont pass options, the defaults are loaded. A full call may look like this:
