简单适用方法

一引入文件

<link rel="stylesheet" href="../res/photoswipe/4.1.1/photoswipe.min.css">
<link rel="stylesheet" href="../res/photoswipe/4.1.1/default-skin/default-skin.min.css">
<script src="../res/photoswipe/4.1.1/photoswipe.min.js"></script>
<script src="../res/photoswipe/4.1.1/photoswipe-ui-default.min.js"></script>

或者（直接使用cdn）

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/photoswipe/4.1.1/photoswipe.min.css">
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/photoswipe/4.1.1/default-skin/default-skin.min.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/photoswipe/4.1.1/photoswipe.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/photoswipe/4.1.1/photoswipe-ui-default.min.js"></script>

二在body内添加div

<!-- 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 slides in DOM to save memory. --><div class="pswp__container"><!-- don't modify these 3 pswp__item elements, data is added later on --><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><!-- Preloader demo https://codepen.io/dimsemenov/pen/yyBWoR --><!-- 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>

三定义js方法

var openPhotoSwipe = function(idx) {var pswpElement = document.querySelectorAll('.pswp')[0];var arr=myOrderInfo.obj.paymentVoucher.split(",");//arr=['http://xxx/a.jpg','http://xxx/b.jpg']"var items2=[];for(var i=0;i<arr.length;i++){var ob={src: arr[i],w: 1024,h: 1024};items2[items2.length]=ob;}// build items arrayvar items = [{html: '<div class="hello-slide"><h1>Hello world <a href="http://example.com">example.com</a></h1></div>'},{src: 'aa.jpg',w: 1024,h: 1024}];// define options (if needed)var options = {index:idx,//展示第几个(下标从0开始)// history & focus options are disabled on CodePen        history: false,focus: false,showAnimationDuration: 0,hideAnimationDuration: 0};var gallery = new PhotoSwipe( pswpElement, PhotoSwipeUI_Default, items2, options);gallery.init();};
