背景

依学校老师之托，顺便深入学习和应用 Vue.js 和 Php

准备重新做个成绩管理系统(Learning Management System , LMS)，叫「Eugrade」，之后 可能会涉及到很多新东西

大概会等考完6月份的考试再继续做...

持续更新中...

↑ Javascript 部分

 

git clone git@github.com:HelipengTony/eugrade.git

↑ PHP 部分太长了，放在 Github 了

css 就不配了，Element UI 有自带的...

 

批注

Element UI 提供了一些表单验证的 API，点击这里可以看到文档

结合 Php 来实现实时验证用户名、邮箱可用性...

Php 这次开始试着使用「类」来实现逻辑，确实感觉方便(优雅)许多 🙂
