哈哈！继续选课系统。把选课的两个界面呈上
来，上代码！
<!DOCTYPE html> <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>show page</title> <style type="text/css"> body{ background: #d7c7e9; align-items: center; text-align: center; } </style> </head> <body> <h3>选择课程：</h3> <form action="verifyWindow.jsp" method="get"> 课程名称:<input list="classnames" name="classname"> <datalist id="classnames"> <option value="Java语言" > <option value="统一建模语言" > <option value="数据结构与算法" > <option value="杨老师" > <option value="王老师" > </datalist><br> 教师名称:<input list="teachers" name="teacher"> <datalist id="teachers"> <option value="王建民" > <option value="刘立嘉" > <option value="刘丹" > <option value="杨老师" > <option value="王老师" > </datalist><br> 上课地点:<input list="places" name="place"> <datalist id="places"> <option value="基教"> <option value="一教"> <option value="二教"> <option value="三教"> </datalist><br> <input type="submit"value="选课"> </form> </body> </html>
