  • 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.

    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)

    208. 		if(hashData.pid && hashData.gid) {
    209. 			openPhotoSwipe( hashData.pid ,  galleryElements[ hashData.gid - 1 ], true, true );
    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
