Adding descriptions inside a blueimp gallery

javascript blueimp
Yaël Levey picture Yaël Levey · Nov 4, 2013 · Viewed 13.4k times · Source

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.

I also want to add in some descriptive text and a button to each slide of the lightbox, but I am having trouble making it work. It won't show the placeholder descriptions that I have added in.

Here's what I have so far;

HTML:

<div id="blueimp-gallery" class="blueimp-gallery">
    <!-- The container for the modal slides -->
    <div class="slides"></div>
    <!-- Controls for the borderless lightbox -->
    <h3 class="title"></h3>
    <p class="description"></p>
    <a class="prev">‹</a>
    <a class="next">›</a>
    <a class="close">×</a>
    <a class="play-pause"></a>
    <ol class="indicator"></ol>

    <div class="modal fade">
        <div class="modal-dialog">
            <div class="modal-content">
                <div class="modal-header">
                    <button type="button" class="close" aria-hidden="true">&times;</button>
                    <h4 class="modal-title"></h4>
                </div>
                <div class="modal-body next"></div>
                <div class="modal-footer">
                    <button type="button" class="btn btn-default pull-left prev">
                        <i class="glyphicon glyphicon-chevron-left"></i>
                        Previous
                    </button>
                    <button type="button" class="btn btn-primary next">
                        Next
                        <i class="glyphicon glyphicon-chevron-right"></i>
                    </button>
                </div>

CSS:

.blueimp-gallery > .description {
  position: absolute;
  top: 30px;
  left: 15px;
  color: red;
  display: none;
}

.blueimp-gallery-controls > .description {
  display: block;
}

JS:

blueimp.Gallery(
    document.getElementById('links'),
    {
        onslide: function (index, slide) {
            var text = this.list[index].getAttribute('data-description'),
                node = this.container.find('.description');
            node.empty();
            if (text) {
                node[0].appendChild(document.createTextNode(text));
            }
        }
    }
);

And in my body (gallery.js is the file where I've added the above JS):

  <script src="//code.jquery.com/jquery.js"></script>
  <script src="js/bootstrap.min.js"></script>
  <script src="lib/fancybox/jquery.fancybox.js"></script>
  <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
  <script src="http://blueimp.github.io/Gallery/js/jquery.blueimp-gallery.min.js"></script>
  <script src="js/bootstrap-image-gallery.min.js"></script>
  <script src="js/gallery.js"></script>

Any pointers on where I've gone wrong would be much appreciated!

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:

<div id="blueimp-gallery" class="blueimp-gallery">
    <div class="slides"></div>
    <h3 class="title"></h3>
    <p class="description"></p>
    <p class="example"></p>
    ...
</div>
------
<div id="links">
    <a href="images/banana.jpg" title="Banana" data-description="This is a banana." data-example="Additional data">Banana</a>
    <a href="images/apple.jpg" title="Apple" data-description="This is an apple." data-example="Additional data">Apple</a>
</div>

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;
}
