本人学编程半年学校有个it精英赛做一个html网页刚刚学完html 但是想做一个根据输入内容判断回复内容的机器人客服界面
并且是在当前页面刷新
下面是已经写好的代码：
1.index.jsp
<%@ 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>
<base href="<%=basePath%>">

<title>My JSP 'index.jsp' starting page</title>
<link rel="stylesheet" type="text/css" href="Style.css"/>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">


</head>

<body>

<div id="body">

<div id="head">
<form name="One" method="get" action="./quire.do">
<textarea name="txt_1" rows="10" cols="150" id="text_1">输入要查询的球队的名字</textarea>
<input type="submit" value="发送">
</form>
</div>

</div>
</body>
</html>

2.web.xml

public class InquireServlet extends HttpServlet{

//private static Logger logger = Logger .getLogger(Test1_2.class.getName());
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
request.setCharacterEncoding("utf-8");
String name = request.getParameter("txt_1");
name = new String(name.getBytes("iso-8859-1"),"UTF-8");
out.print(name);
if(name!=null){
Connection conn=null;
Statement stmt=null;
ResultSet rs=null;
try{
//加载数据库驱动类
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
}catch(ClassNotFoundException e){
//logger.error(e);
//命令行打印异常信息在程序中出错的位置及原因
e.printStackTrace();
}
try{
//登陆数据库
conn=DriverManager.getConnection("jdbc:sqlserver://127.0.0.1:1433;databasename=K;User=sa;Password=kongrui");
stmt=conn.createStatement();
//从K表单中所有“孔”开头的字符串
//rs=stmt.executeQuery("select * from K where kong like ");

rs=stmt.executeQuery("select * from users where Name like '%"+name+"%'");
request.setAttribute("name1", rs.getString(2));
request.setAttribute("score", rs.getString(3));
request.setAttribute("name2", rs.getString(4));

//输出查询结果
while(rs.next()){
out.print("比分是"+rs.getString(2)+rs.getString(3)+rs.getString(4));
}
}catch (Exception e){
//logger.error(e);
//命令行打印异常信息在程序中出错的位置及原因
e.printStackTrace();
}finally{
System.out.println("再见");
}
}else{
System.out.println("无结果");
}
}
}

现在只可以进行跳转查询如何进行当前页面刷新呢求大神指点因为都是没学过的知识自己也是摸索着来欢迎指正！

用AJAX发送用户输入内容，后台根据这关键词搜索出相关结果，AJAX返回就可以了。不必刷新页面。

后台response或者前台用ajax

		//工作地点
		function erji(id){//（id）是html带过来的值，也可以创建一个（如：var a =$("#你需要的id").val()）
			        $.ajax({    
			        	 data:"id="+id, //需要传到后台的“字段=”+参数
			        	 type : "post", //格式
			        	 dataType: 'json',//返回的json
			             url:"<%=basePath%>dmuser/goEdits.do", 
			             error:function(data){  
					            alert("出错了！！:");  
					        },  
			             success:function(data){  //data是传过来的object，是数组[key,value]。
			                for(var i=0;i<data.length;i++){  //然后循环这个数组取值，
			                     var xValue=data[i].id;    //dada里取这个id字段（key）
			                     var xText=data[i].name;    //data里取这个name字段。(value)
