javascript - 在 blueimp 画廊中添加描述

Question

我正在使用 BlueImp Gallery 将灯箱添加到我的图片库。因此，当您单击图像缩略图时，它会启动一个带有较大版本图像等的灯箱。

我还想在灯箱的每张幻灯片中添加一些描述性文本和一个按钮，但我无法使其正常工作。它不会显示我添加的占位符描述。

这是我目前所拥有的；

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));
            }
        }
    }
);

在我的体内(gallery.js 是我添加上述 JS 的文件):

  <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>

任何关于我哪里出错的指示都将不胜感激!

Answer 1

您可以在 a 元素上传递任何需要的数据，然后将其显示在图库中。我花了很多时间试图找到答案，所以我会把它留在这里。这是一个例子:

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:你可以使用.scss来重构它，但它只是为了举例

.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;
}
