1、web代码整理仅供参考！1 人员简历人员简历姓名：电话：性别：男 女个人介绍结果截图2登录页面 方法一：登录页面function check() var s1=document.myForm.uname.value if(s1.length=0) alert(姓名不能为空) return false var s2=document.myForm.pwd.value if(s2.length12|s2.length6) alert(密码长度必须为6-12！) return false return true姓名:密码: 方法二：登录 姓名： 密码： function check() if(doc

2、ument.getElementById(first).value=) alert(姓名不能为空！) return false if(document.getElementById(second).value.length12) alert(密码的长度必须为6-12！) return false return true结果截图3、显示当前时间import java.io.IOException;import java.io.PrintWriter;import java.util.Date;import javax.servlet.ServletException;import javax.s

3、ervlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;/* * Servlet implementation class Time */public class Time extends HttpServlet private static final long serialVersionUID = 1L; /* * see HttpServlet#HttpServlet() */ public Time() /supe

4、r(); / TODO Auto-generated constructor stub /* * see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response) */ protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException / TODO Auto-generated method stub response.setConten

5、tType(text/hrml;charset=UTF-8); /设置响应输出格式，防止输出中文乱码 PrintWriter out=response.getWriter();/获得向客户发送数据的输出流 Date m=new Date(); out.println(当前时间); out.println(); out.println(h1 color:red;); /设置颜色为红色 out.println(); out.println(); out.println(); /以一级标题显示 out.println(当前时间：+m.toLocaleString(); /out.println();

6、 out.println(); out.println(); out.println(); out.close(); /* * see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response) */ protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException / TODO Auto-generated method stub d

7、oGet(request,response); 结果截图4、数据库的增、删、改、查（1）增加记录Insert.html学生信息录入页面插入学生信息id号：学号：姓名：出生日期：Insert.jsp 插入学生信息插入学生信息%request.setCharacterEncoding(UTF-8);String Id=request.getParameter(id);String Num=request.getParameter(num);String Name=request.getParameter(name);String Birth=request.getParameter(birth);String sql=insert into xsb values(+Id+,+Num+,+Name+,+Birth+);Connection con
