jQuery ajax MD5实现用户注册即时验证功能

(编辑：jimmy 日期: 2024/11/19 浏览：3 次 )

实际项目中比较常用的(JQuery+AJAX+MD5)，属于即时验证，亮点是验证用户是否存在的那一项，具体内容如下

具体示例

registe.jsp

<span style="font-size: large;"><%@ page pageEncoding="UTF-8"%> 
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> 
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %> 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml"> 
<head> 
<title>注册验证</title> 
<script type="text/javascript" src="/UploadFiles/2021-04-02/md5.js">



AccountServlet.java




<span style="font-size: large;">package com.validator.test; 
 
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 AccountServlet extends HttpServlet { 
 
 
 public void doGet(HttpServletRequest request, HttpServletResponse response) 
 throws ServletException, IOException { 
 this.doPost(request, response); 
 
 } 
 public void doPost(HttpServletRequest request, HttpServletResponse response) 
 throws ServletException, IOException { 
 String loginname=request.getParameter("loginname"); 
 PrintWriter out = response.getWriter(); 
 if(loginname.equals("abc123")){ 
 out.println("1"); 
 }else{ 
 out.println("0"); 
 } 
 out.flush(); 
 
 } 
 
}</span>
