Adding descriptions inside a blueimp gallery

Question

I am using a BlueImp Gallery to add lightboxes to my image gallery. So, when you click on an image thumbnail, it launches a lightbox with a larger version of the image etc.<

Answer 1

You can pass any needed data on a element, and then display it in the gallery. I spend a lot of time trying to find an answer, so I'll leave it here. Here is an example:

HTML:

    

    

    

    

    ...

------

    Banana
    Apple

JS:

document.getElementById('links').onclick = function (event) {
  event = event || window.event;
  var target = event.target || event.srcElement,
    link = target.src ? target.parentNode : target,
    options = {
      index: link, event: event,
      onslide: function (index, slide) {

        self = this;
        var initializeAdditional = function (index, data, klass, self) {
          var text = self.list[index].getAttribute(data),
            node = self.container.find(klass);
          node.empty();
          if (text) {
            node[0].appendChild(document.createTextNode(text));
          }
        };
        initializeAdditional(index, 'data-description', '.description', self);
        initializeAdditional(index, 'data-example', '.example', self);
      }
    },
    links = this.getElementsByTagName('a');
  blueimp.Gallery(links, options);
};

CSS: You can use .scss to refactor it, but it's just for example

.blueimp-gallery > .description, .blueimp-gallery > .example {
  position: absolute;
  top: 30px;
  left: 15px;
  color: #fff;
  display: none;
}
.blueimp-gallery-controls > .description, .blueimp-gallery-controls > .example {
  display: block;
}
