Question

我有一个图片库，我想点击每个图片以显示4个相关图像。如果不为每个图像创建一个新页面以显示其相关图像，最好的方法是什么？

我将其用于图片库： http://codepen.io/dimsemenov/pen/ZYbPJM

现在我使用Adobe InDesign在一个png文件中显示四个图像（由于空间限制），但当然还有更多美学和智能方式。请提出解决方案。

        } else {

        }

            options.showAnimationDuration = 0;
        }

        // Pass data to PhotoSwipe and initialize it
        gallery = new PhotoSwipe( pswpElement, PhotoSwipeUI_Default, items, options);
        gallery.init();
    };

    // loop through all gallery elements and bind events
    var galleryElements = document.querySelectorAll( gallerySelector );

    for(var i = 0, l = galleryElements.length; i < l; i++) {
        galleryElements[i].setAttribute('data-pswp-uid', i+1);
        galleryElements[i].onclick = onThumbnailsClick;
    }

    // Parse URL and open gallery if it contains #&pid=3&gid=1
    var hashData = photoswipeParseHash();
    if(hashData.pid && hashData.gid) {
        openPhotoSwipe( hashData.pid ,  galleryElements[ hashData.gid - 1 ], true, true );
    }
};

// execute above function
initPhotoSwipeFromDOM('.my-gallery');

这是CSS：

.my-gallery {
  width: 100%;
  float: left;
}

.my-gallery img {
  width: 200px;
  height: 200px;
  display: block;
}
.my-gallery figure {
  display: block;
  float: left;
  margin: 0px 15px 20px 0;
  border: 3px solid #000;

}

.my-gallery figcaption {
  display: none;
}

还有一种更简单的方法来使用此图库而不使用上面的这个库吗？

基本上我想在你点击图片时显示这样的东西： ^上面是用adobe illustrator制作的，用html / css很好用。

这就是画廊本身的显示方式：

Answer 1

您可以使用Fancybox实现此目的。

See this Fiddle.

在此示例中，单击可见图像会触发单击事件，该事件将使用Fancybox打开隐藏的图库。

HTML

<!-- Your visible image(s) -->
    <a class="fancyboxLauncher" href="http://fancyapps.com/fancybox/demo/1_b.jpg" title="one"><img src="http://fancyapps.com/fancybox/demo/1_s.jpg" alt="" /></a>

<!-- Your hidden gallery -->    
    <div style="display: none;">
    <a class="fancybox" href="http://farm4.staticflickr.com/3712/9032543579_1217e6566b_b.jpg" title="one"></a>

<a class="fancybox" href="http://farm4.staticflickr.com/3818/9036037912_83576fe5ab_b.jpg" title="two"></a>

JS

// Trigger event
$(".fancyboxLauncher").on("click", function () {
    $(".fancybox").eq(0).trigger("click");
    return false;
});

// Init Fancybox
$(".fancybox")
    .attr('rel', 'gallery')
    .fancybox({
    padding: 0
});

当然你仍然可以使用4合1图像，只需使用1张图像而不是4张。无论如何，你有很多选择。

单击图库中的图像并在同一页面中显示多个图像
