本文分享了一个仿百度图片浏览效果的实现案例，通过使用HTML、CSS和jQuery，创建了一个包含图片显示、缩放和平移功能的图片浏览界面。代码包括了图片预览、全屏模式、缩放控制和导航按钮等功能。
转载来源：https://www.jb51.net/article/98030.htm
这是一个非常好的案例，然而jquery的时代正在徐徐关闭。
当你调整浏览器宽高，你会发现它不是自适应的。当你想把它放到elementUI项目中是，你发现不行！
如果你项目采用了vue和elementUI,建议以找找vue实现版本，或者单纯js版本。
本文实例为大家分享了js图片浏览效果的具体代码，供大家参考，具体内容如下
