HTML

<div id="photos"> 
    <img src="images/s1_m.jpg" alt="Image description" /> 
    <p>图集</p> 
</div>

引入photoswipe相关组件

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

我们分析下大图展示结构，提示以下代码中的标签样式：.pswp__bg, .pswp__scroll-wrap, .pswp__container 和 .pswp__item这几个Div不可更改。

<div class="pswp" tabindex="-1" role="dialog" aria-hidden="true"> 
    <div class="pswp__bg"></div> 
    <div class="pswp__scroll-wrap"> 
        <div class="pswp__container"> 
            <div class="pswp__item"></div> 
            <div class="pswp__item"></div> 
            <div class="pswp__item"></div> 
        </div> 
 
        <div class="pswp__ui pswp__ui--hidden"> 
            <div class="pswp__top-bar"> 
                <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> 
                <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>

js

我们在js里定义列表模式图片集合（当然也可以像<a href='https://jy.tp.yuanmeng.life/js/381/demo/index2.html'>demo2</a>一样在html部分定义图片集），然后设置API，最后调用photoSwipe插件new PhotoSwipe()。

var openPhotoSwipe = function() { 
    var pswpElement = document.querySelectorAll('.pswp')[0]; 
    //定义图片集合 
    var items = [ 
        { 
            src: 'images/s1.jpg', 
            w: 800, 
            h: 1142 
        }, 
        { 
            src: 'images/s2.jpg', 
            w: 800, 
            h: 1142 
        } 
    ]; 
     
    var options = { 
        history: false, 
        focus: false, 
 
        showAnimationDuration: 0, 
        hideAnimationDuration: 0 
         
    }; 
     
    var gallery = new PhotoSwipe( pswpElement, PhotoSwipeUI_Default, items, options); 
    gallery.init(); 
}; 
//点击图集元素时触发调用openPhotoSwipe 
document.getElementById('photos').onclick = openPhotoSwipe;
