前端三大件html,css,js原生实现学生信息管理系统（课程设计）

话不多说，直接上代码，有用麻烦点个免费的赞赞。超级好用版。

目录结构如该图所示，只要将文件命名成图上三种。代码即可正常运行。分别有三个文件，一个是app.js，放学生信息删除添加查询主要逻辑代码。login.html放登录页面样式以及相关逻辑。studentList.html 放置学生管理的页面。

运行效果图：

代码：

 app.js

let temData = {
  studentList: [{
    id: '1',
    name: "爱吃饭的小恐龙",
    age: "20",
    gender: "男",
  },
  {
    id: '2',
    name: "付渐渐",
    age: "19",
    gender: "男",
  }]
}

$(document).ready(function () {
  // 执行页面加载时获取学生列表
  getStudentList();

  //退出登录
  $('.loginOut').click(function () {
    loginOut();
  });
  // 监听添加学生信息表单提交事件
  $('.box1').submit(function (event) {
