这是一个WEB项目，需要在网页上显示，只是初学，没有涉及到后面一些东西。我把添加用户的代码放在了下面，用Myeclipse写的，我想加上Ajax让他注册不能重名，该在哪里做出修改呢？先谢谢大家了这个是userAdd.jsp 增加用户的页面<%@ 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 4.01 Transitional//EN"><html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>无标题文档</title><link href="css/style.css" rel="stylesheet" type="text/css" /></head> </head> <body> <div class="place"> <span>位置：</span> <ul class="placeul"> <li><a href="index.jsp">首页</a></li> <li><a href="#">添加账户</a></li> </ul> </div> <div class="formbody"> <div class="formtitle"> <span>基本信息</span> </div> <div class="formbody"> <form action="<%=path%>/servlet/UserAddServlet" method="post" ><ul class="forminfo"> <li><label> 用户名:</label><input name="uname" type="text" class="dfinput" ></li> <li><label> 密码：</label><input name="upass" type="password" class="dfinput" ></li> <li><label > 权限:</label></li> <li><label style="margin-left: 150px">财务</label><input type="radio" name="quanxian" value="财务" checked="checked" style="margin-top: 12px" /></li> <li><label style="margin-left: 150px">人事</label><input type="radio" name="quanxian" value="人事" style="margin-top: 10px" /></li> <li><label> </label><input name="" type="submit" class="btn" value="确认保存" /></li></ul> </form> </div> </body></html>下面这个是UserAddServlet 后台操作数据package com.xx.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;import com.xx.bean.User;import com.xx.dao.UserDao;
