    quitOnEscKey:   true                     // bool;            quit when Esc key is pressed
});

Starting lightbox with JavaScript call

imageLightBox can be started with startImageLightbox() JavaScript function call.

Example:

<script src="jquery.js"></script>
<script src="imagelightbox.js"></script>
<script>
    $( function()
    {
        var gallery = $( selector ).imageLightbox();
        gallery.startImageLightbox();
    });
</script>

Adding captions to lightbox

add an "ilb2-caption" data-attribute to the element, fallback value is the alt-attribute of the thumbnail-image

    <a data-imagelightbox="x" data-ilb2-caption="caption text"
        href="image.jpg">
        <img src="thumbnail.jpg" alt="fallback caption"/>
    </a>

Fullscreen

Simply set the fullscreen option to true to enable the option. If the user's browser supports the fullscreen API, they can switch to fullscreen mode by pressing enter.

Hooks

Image Lightbox now triggers unique events upon start, finish, and when either the next or previous image is requested. These events are, respectively, "start.ilb2", "quit.ilb2", "loaded.ilb2", "next.ilb2", and "previous.ilb2".

Usage example:

 $(document)
    .on("start.ilb2", function () {
    console.log("Image Lightbox has started.");
    })
    .on("next.ilb2", function () {
    console.log("Next image");
    })
    .on("previous.ilb2", function () {
    console.log("Previous image");
    })
    .on("quit.ilb2", function () {
    console.log("Image Lightbox has quit.");
    });

Using multiple sets

As of commit bf2b4db, imageLightbox supports "sets." A set is defined by the links with a common value for the "data-imagelightbox" attribute.

For example:

    <a data-imagelightbox="a"
        href="image_1.jpg">
        <img src="thumbnail_1.jpg" alt="caption"/>
    </a>
    <a data-imagelightbox="a"
        href="image_2.jpg">
        <img src="thumbnail_2.jpg" alt="caption"/>
    </a>

    <a data-imagelightbox="b"
        href="image_3.jpg">
        <img src="thumbnail_3.jpg" alt="caption"/>
    </a>
    <a data-imagelightbox="b"
        href="image_4.jpg">
        <img src="thumbnail_4.jpg" alt="caption"/>
    </a>

When the user clicks any of the thumbnails with a data-imagelightbox value of "a", only those images will appear in the lightbox. The same is true when clicking an image with data-imagelightbox value of "b" and any other.

If you want unlimited gallerys call this snippet (for example: https://jsfiddle.net/7ow26fcg/):

(Используйте этот код вызова lightbox, если у вас на странице несколько галерей, где у каждой галереи уникальное значение атрибута data-imagelightbox. Например data-imagelightbox="gallery_1", data-imagelightbox="gallery_2" и т.д.)

<script>
    var attrs = {};
    var classes = $("a[data-imagelightbox]").map(function(indx, element){
      var key = $(element).attr("data-imagelightbox");
      attrs[key] = true;
      return attrs;
    });
    var attrsName = Object.keys(attrs);

    attrsName.forEach(function(entry) {
        $( "[data-imagelightbox='"+entry+"']" ).imageLightbox({
            overlay: true
        });
    });
</script>

In order to "capture" all possible sets on a give webpage, it is necessary to apply imageLightbox to "a[data-imagelightbox]"; that is, without specifying a particular data-imagelightbox attribute value.

Adding images dynamically to lightbox

imageLightBox allows adding more images dynamically at runtime

Example:

<script src="jquery.js"></script>
<script src="imagelightbox.js"></script>
<script>
    $( function()
    {
        var gallery = $( selector ).imageLightbox();
        var image = $( '<img />' );
        gallery.addToImageLightbox( image );
    });
</script>
