3. 2020.2.13，用bootstrap框架完成了管理员添加和修改的页面实现，并加入jQuery校验字段是否为空，最终实现了管理员添加以及修改功能。
4. 2020.2.14，把原来的登录页面更换成动态特效的登录页面，并使用ajax完成登录的后台校验，管理员查询功能完成了模糊查询，但是模糊查询带上分页技术后页面跳转出现问题（点击分页按钮后又重新查询了全部数据的分页），查看了相关资料，进行改进，目前并未完全实现。
5. 2020.2.15，实现了管理员信息模糊查询并分页的效果，并增加了超级管理员可给普通管理员授权的功能，着手实现数据导出功能，发现程序运行时报错，经验证后发现是json格式从后台传向前台需要经过解析，故导入了相关依赖即可，而后又遇到layui的Excel模块不可用，开始着手解决。
6. 2020.2.16，实现了管理员数据Excel格式的导出，并可以指定保存位置。
