jsp实验源码

在JSP中怎么实现多项选择题,可以给以下源代码,

你说的多项选择题，我是验源灵签源码不是可以理解成多选

多选的实现是这样的：

第一：必须将多选框放到form里面。

第二：然后name属性完全一样，验源apt 源码value不相同。验源stardict 源码这样当你提交到Action中的验源smartfoxserver 源码时候，只需要使用request对象获取toselect的验源uclibc源码值就行了。

第三：获取值：request.getParameterValues("toselect")，验源就会将选中的验源多选框里面的value获取，并且返回一个String[]数组，验源这个数组里面就有你想要的验源值：即选中的值

<html>

<body>

<form>

<input type = "checkbox" value = "A" name = "toselect"/>A

<input type = "checkbox" value = "B" name = "toselect"/>B

<input type = "checkbox" value = "C" name = "toselect"/>C

<input type = "checkbox" value = "D" name = "toselect"/>D

</form>

</body>

</html>

登陆页面 index.jsp源码：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4. Transitional//EN">

<html>

<head>

<title>login</title>

<!--

</head>

<body>

用户名：<input type="text" name="username" ><br>

密码:<input type="password" name="userpass"><br>

</form>

</body>

LoginServlet.java 源码：

package servlet;

import java.io.IOException;

import java.io.PrintWriter;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

public class LoginServlet extends HttpServlet {

* Constructor of the object.

public LoginServlet() {

super();

}

* Destruction of the servlet. <br>

public void destroy() {

super.destroy(); // Just puts "destroy" string in log

// Put your code here

}

* The doGet method of the servlet. <br>

* This method is called when a form has its tag value method equals to get.

* @param request the request send by the client to the server

* @param response the response send by the server to the client

* @throws ServletException if an error occurred

* @throws IOException if an error occurred

public void doGet(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {

//获得jsp页面传输的参数

String username=request.getParameter("username");

String userpass=request.getParameter("userpass");

//判断

if(username.equals("user")&&userpass.equals("")){

response.sendRedirect("1.jsp");

}else if(username.equals("admin")&&userpass.equals("")){

response.sendRedirect("2.jsp");

}else{

response.sendRedirect("index.jsp");

}

* The doPost method of the servlet. <br>

* This method is called when a form has its tag value method equals to post.

* @param request the request send by the client to the server

* @param response the response send by the server to the client

* @throws ServletException if an error occurred

* @throws IOException if an error occurred

public void doPost(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {

this.doGet(request, response);

}

* Initialization of the servlet. <br>

* @throws ServletException if an error occurs

public void init() throws ServletException {

// Put your code here
