js photoswipe 相册使用 移动pc端均可


官网  这里使用的是最新 4.1.1版本
文档


解压  copy dist文件夹至工程目录  引入

  1. <link rel="stylesheet prefetch" href="${baseURL}/js/3rd-plug/PhotoSwipe-4.1.1/photoswipe.css">
  2. 	<link rel="stylesheet prefetch" href="${baseURL}/js/3rd-plug/PhotoSwipe-4.1.1/default-skin/default-skin.css">
  3. 	<script src="${baseURL}/js/3rd-plug/PhotoSwipe-4.1.1/photoswipe.js"></script>
  4. 	<script src="${baseURL}/js/3rd-plug/PhotoSwipe-4.1.1/photoswipe-ui-default.min.js"></script>

加上控件 所需要的html ，这样可以直接改html 使控件变样式 ，而不用配参数

  1. <!-- Root element of PhotoSwipe. Must have class pswp. -->
  2. <div class="pswp" tabindex="-1" role="dialog" aria-hidden="true" style="top: 40px;height: 95%;">
  4. 	<!-- Background of PhotoSwipe.
  5.          It's a separate element as animating opacity is faster than rgba(). -->
  6. 	<div class="pswp__bg"></div>
  8. 	<!-- Slides wrapper with overflow:hidden. -->
  9. 	<div class="pswp__scroll-wrap">
  11. 		<!-- Container that holds slides.
  12.             PhotoSwipe keeps only 3 of them in the DOM to save memory.
  13.             Don't modify these 3 pswp__item elements, data is added later on. -->
  14. 		<div class="pswp__container">
  15. 			<div class="pswp__item"></div>
  16. 			<div class="pswp__item"></div>
  17. 			<div class="pswp__item"></div>
  18. 		</div>
  20. 		<!-- Default (PhotoSwipeUI_Default) interface on top of sliding area. Can be changed. -->
  21. 		<div class="pswp__ui pswp__ui--hidden">
  23. 			<div class="pswp__top-bar">
  25. 				<!--  Controls are self-explanatory. Order can be changed. -->
  27. 				<div class="pswp__counter"></div>

  37. 				<!-- Preloader demo http://codepen.io/dimsemenov/pen/yyBWoR -->
  38. 				<!-- element will get class pswp__preloader--active when preloader is running -->
  39. 				<div class="pswp__preloader">

  43. 						</div>
  44. 					</div>
  45. 				</div>
  46. 			</div>
  48. 			<div class="pswp__share-modal pswp__share-modal--hidden pswp__single-tap">

  60. 			</div>
  62. 		</div>
  64. 	</div>
  66. </div>

这段html 可以配置控件的默认  如让箭头显示等样式


接下来配置初始化js   该JS是初始化一个相册列表 ，需要点击才能放大  ， 当然可以模拟点击，具体看下面

  1. var initPhotoSwipeFromDOM = function(gallerySelector) {
  3. 		// parse slide data (url, title, size ...) from DOM elements
  4. 		// (children of gallerySelector)
  5. 		var parseThumbnailElements = function(el) {

  20. 					continue;
  21. 				}

  210. 		}
  211. 	};

具体参数可以看文档

准备自定义的html（从服务器获取的数据）

  1. <div class="my-gallery" itemscope itemtype="http://schema.org/ImageGallery" style="display: none">
  2. 	<c:forEach items="${requestScope.housePhotoes}" var="housePhoto" >
  3. 	<figure itemprop="associatedMedia" itemscope itemtype="http://schema.org/ImageObject">
  4. 		<a href="${housePhoto.photourl}" itemprop="contentUrl" data-size="1024x1024">
  5. 			<img src="${housePhoto.photourl}" itemprop="thumbnail" alt="Image description" />
  6. 		</a>
  7. 		<figcaption itemprop="caption description">${housePhoto.photoDescrition}</figcaption>
  9. 	</figure>
  10. 	</c:forEach>
  14. </div>

调用初始化方法传入自定义的class name  并模拟点击

  1. initPhotoSwipeFromDOM('.my-gallery');
  4. 	$(function(){
  5. 		$(".my-gallery").find('figure')[0].click()
  6. 	})


OK 搞定
