weui框架实现上传、预览和删除图片功能代码框架实现上传、预览和删除图片功能代码
jQuery WeUI 是专为微信公众账号开发而设计的一个简洁而强大的UI库，包含全部WeUI官方的CSS组件，并且额外提供了大
量的拓展组件，丰富的组件库可以极大减少前端开发时间。
jQuery WeUI 的最大特点是它只提供UI组件，并不会对项目所使用的框架和其他库有任何的限制，几乎可以在任何环境下使
用。无论你的项目是基于jQuery，还是 React, Angular, Vue， 你都会发现 jQuery WeUI 能非常方便的和他们结合使用。既是
你的项目是一个有很悠久历史的老项目，也几乎可以做到拿来即用。
weui框架暂时只有css文件，并没有js文件实现其功能，我在其html+css后面增加了js实现其功能，为大家提供方便，也为自
己保存记录。
