<link rel="stylesheet prefetch" href="css/default-skin/default-skin.css">
<script src="/UploadFiles/2021-04-02/photoswipe.js">

2、页面中必须加入以下代码结构（此结构是插件图片浏览必须代码，作者并没有集成到js中，所以使用者必须手动加入自己的网页中）：




<!-- Root element of PhotoSwipe. Must have class pswp. -->
<div class="pswp" tabindex="-1" role="dialog" aria-hidden="true">

 <!-- Background of PhotoSwipe. 
 It's a separate element as animating opacity is faster than rgba(). -->
 <div class="pswp__bg"></div>

 <!-- Slides wrapper with overflow:hidden. -->
 <div class="pswp__scroll-wrap">

 <!-- Container that holds slides. 
 PhotoSwipe keeps only 3 of them in the DOM to save memory.
 Don't modify these 3 pswp__item elements, data is added later on. -->
 <div class="pswp__container">
 <div class="pswp__item"></div>
 <div class="pswp__item"></div>
 <div class="pswp__item"></div>
 </div>

 <!-- Default (PhotoSwipeUI_Default) interface on top of sliding area. Can be changed. -->
 <div class="pswp__ui pswp__ui--hidden">

 <div class="pswp__top-bar">

 <!-- Controls are self-explanatory. Order can be changed. -->

 <div class="pswp__counter"></div>

 <button class="pswp__button pswp__button--close" title="Close (Esc)"></button>

 <button class="pswp__button pswp__button--share" title="Share"></button>

 <button class="pswp__button pswp__button--fs" title="Toggle fullscreen"></button>

 <button class="pswp__button pswp__button--zoom" title="Zoom in/out"></button>

 <!-- element will get class pswp__preloader--active when preloader is running -->
 <div class="pswp__preloader">
  <div class="pswp__preloader__icn">
  <div class="pswp__preloader__cut">
  <div class="pswp__preloader__donut"></div>
  </div>
  </div>
 </div>
 </div>

 <div class="pswp__share-modal pswp__share-modal--hidden pswp__single-tap">
 <div class="pswp__share-tooltip"></div> 
 </div>

 <button class="pswp__button pswp__button--arrow--left" title="Previous (arrow left)">
 </button>

 <button class="pswp__button pswp__button--arrow--right" title="Next (arrow right)">
 </button>

 <div class="pswp__caption">
 <div class="pswp__caption__center"></div>
 </div>

 </div>

 </div>

</div>




3、需要浏览的图片加入photoswipe结构代码，这里需要注意的是

 data-pswp-uid在每个相册中必须是唯一的，data-size是指定放大时图片显示的宽和高，若指定的宽高与图片不符会导致显示的图片变形；目前还没找到去掉 data-size的办法，但然有时间可以找下替代办法。




<!--data-pswp-uid在每个相册中必须是唯一的，data-size指定放大时图片显示的宽和高-->
<div class="my-gallery" data-pswp-uid="1">
　　<figure>
  <a href="img/m3.jpg" data-size="670x712">
  <img src="/UploadFiles/2021-04-02/th1.jpg">

4、加入js代码，此代码作者也没有集成到photoswipe框架中，需要自己手动加入网页里




<script type="text/javascript">
 var initPhotoSwipeFromDOM = function(gallerySelector) {

 // 解析来自DOM元素幻灯片数据（URL，标题，大小...）
 // (children of gallerySelector)
 var parseThumbnailElements = function(el) {
 var thumbElements = el.childNodes,
 numNodes = thumbElements.length,
 items = [],
 figureEl,
 linkEl,
 size,
 item;

 for(var i = 0; i < numNodes; i++) {

 figureEl = thumbElements[i]; // <figure> element

 // 仅包括元素节点
 if(figureEl.nodeType !== 1) {
 continue;
 } 25 linkEl = figureEl.children[0]; // <a> element
 
 size = linkEl.getAttribute('data-size').split('x');

 // 创建幻灯片对象
 item = {
 src: linkEl.getAttribute('href'),
 w: parseInt(size[0], 10),
 h: parseInt(size[1], 10)
 };


 if(figureEl.children.length > 1) {
 // <figcaption> content
 item.title = figureEl.children[1].innerHTML; 
 }

 if(linkEl.children.length > 0) {
 // <img> 缩略图节点, 检索缩略图网址
 item.msrc = linkEl.children[0].getAttribute('src');
 }

 item.el = figureEl; // 保存链接元素 for getThumbBoundsFn
 items.push(item);
 }

 return items;
 };

 // 查找最近的父节点
 var closest = function closest(el, fn) {
 return el && ( fn(el) "_blank" href="https://www.jb51.net/Special/879.htm">JavaScript微信开发技巧汇总》，欢迎大家学习阅读。
