点击小图查看大图，双指缩放，点击放大，流畅度爆爽
[复制链接]
今天分享的是一个图片列表页点击小图查看大图的功能的插件，原生JS，流畅度100%，纯前段
双指缩放，双击放大，拖动切换，上拉或下拉退出，有进度条，分页。可以完美替代相册模块。
需要用到的插件photoswipe。先来张效果图片
图片列表容器代码：
<div class="my-simple-gallery">
<figure itemprop="associatedMedia" itemscope=""><a href="原图地址" data-size="图片尺寸（格式300X300）"><img src="缩略图"></a></figure>
<figure itemprop="associatedMedia" itemscope=""><a href="原图地址" data-size="图片尺寸（格式300X300）"><img src="缩略图"></a></figure>
</div>
给列表使用函数
initPhotoSwipeFromDOM('.my-simple-gallery');
大图展示的容器,看不明白可以直接拿去使用的
<div class="pswp" tabindex="-1" role="dialog" aria-hidden="true" style="">
<div class="pswp__bg"></div>
<div class="pswp__scroll-wrap">
<div class="pswp__container" style="transform: translate3d(0px, 0px, 0px);">
<div class="pswp__item" style="display: block; transform: translate3d(-1792px, 0px, 0px);">
<div class="pswp__zoom-wrap" style="transform: translate3d(288px, 56px, 0px) scale(1);"></div>
</div>
<div class="pswp__item" style="transform: translate3d(0px, 0px, 0px);">
<div class="pswp__zoom-wrap" style="transform: translate3d(473px, 66.8125px, 0px) scale(0.146484375);"></div>
</div>
<div class="pswp__item" style="display: block; transform: translate3d(1792px, 0px, 0px);">
<div class="pswp__zoom-wrap" style="transform: translate3d(447px, 44px, 0px) scale(0.6904296875);"></div>
</div>
</div>
