功能要求

1、完成两个页面

2、第一个登陆页面login. jsp

3、第二个用户管理页面useManage. jsp

4、有登录功能(能进行用户名密码的校验，用户名若为自己的学号密码为班级号，允许登录，否则不显示用户数据列表)，有退出功能。

5、操作列添加“删除”按钮，使用JavaScr ipt实现用户删除功能。

6、操作列添加“添加星座”按钮，使用JavaScr ipt实现添加星座功能( 注意使用询问框(prompt) :获取输入的值)。

1.文件建立

2.BootStrap和jQuery引入

Bootstrap4.6.1下载网址

3.login.jsp编写

<%@ page contentType="text/html;charset=UTF-8" language="java" %>

<html>

<head>

    <title>登录</title>

    <link rel="stylesheet" type="text/css" href="bootstrap-4.6.1-dist/css/bootstrap.css"/>

</head>

<body>

<div style="align-content: center; width: 400px; height: 250px;text-align: center;margin:200px 500px;">

<form action="useManage.jsp" method="post">

    <div class="form-group row">

        <label for="inputPassword" class="col-sm-2 col-form-label">姓名:</label>

        <div class="col-sm-10">

            <input type="text" class="form-control" name="uname">

<script type="text/javascript" src="bootstrap-4.6.1-dist/js/jquery-3.6.1.min.js"></script>

<script type="text/javascript" src="bootstrap-4.6.1-dist/js/bootstrap.js"></script>

为了方便测试，此处账号和密码设为了 admin和123456，可自行修改。

<%@ page contentType="text/html;charset=UTF-8" language="java" %>

<html>

<head>

    <title>用户管理</title>

    <link rel="stylesheet" type="text/css" href="bootstrap-4.6.1-dist/css/bootstrap.css"/>

</head>

<body>

<div style="width: 1000px;height: 600px;margin: 100px 250px">

<div >

<span style="margin: 150px;font-size: 20px">用户管理</span>

<span style="font-size: 20px">登录人：<% out.println("admin");%></span>

 <a href="login.jsp"><button class="btn btn-primary" style="float: right;margin:0px 200px">退出</button></a>

<span style="color:red;font-size:12px">${msg}</span>

</div>
