            <!-- demo1 json-->
            <h4>json方式返回</h4>
            <form id="myForm" action="json.jsp" method="post"> 
                名称: <input type="text" name="name" id="name" /> <br/>

                <input type="submit" id="test" value="json方式返回" /> <br/>
                <div id="jsonOut" ></div>
            </form>
            
             
            <!-- demo2 xml-->
            <h4>xml方式返回</h4>
            <form id="xmlForm" action="xml.jsp" method="post"> 
                名称: <input type="text" name="xmlname" id="xmlname" /> <br/>
                地址: <input type="text" name="xmladdress" id="xmladdress"/><br/> 
                自我介绍: <textarea name="xmlcomment" id="xmlcomment" ></textarea> <br/>
                <input type="submit" id="xmltest" value="xml方式返回" /> <br/>
                <div id="xmlOut" ></div>
            </form>
            
            
            <!-- demo3 html-->
            <h4>html方式返回</h4>
            <form id="htmlForm" action="html.jsp" method="post"> 
                名称: <input type="text" name="htmlname" id="htmlname" /> <br/>
                地址: <input type="text" name="htmladdress" id="htmladdress"/><br/>

            </form>
    
      </body>
    </html>

    新建json.jsp文件:

    <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
    <%
    request.setCharacterEncoding("UTF-8");//防止乱码!
    String name = request.getParameter("name");
    String address = request.getParameter("address");
    String comment = request.getParameter("comment");
    System.out.println(name + " - " +address + " - " +comment);
    out.println( "{ name : '" +name+ "' , address :  '"+address+ "' ,comment :  '"+comment+ "' }" );
    %>

    新建xml.jsp文件:

    <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
    <%
    request.setCharacterEncoding("UTF-8");//防止乱码!
    String name = request.getParameter("xmlname");
    String address = request.getParameter("xmladdress");
    String comment = request.getParameter("xmlcomment");
    System.out.println(name + " - " +address + " - " +comment);
    response.setContentType("text/xml");//注意,由于你是以xml形式传递过来的,所以这里必须写。
    out.print("<?xml version="1.0" encoding="UTF-8"?>");
    out.print("<root>");
    out.print("<name>"+name+"</name>");
    out.print("<address>"+address+"</address>");
    out.print("<comment>"+comment+"</comment>");
    out.print("</root>");
    %>

    新建一个html.jsp文件:

    <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
    <%
    request.setCharacterEncoding("UTF-8");//防止乱码!
    String name = request.getParameter("htmlname");
    String address = request.getParameter("htmladdress");
    String comment = request.getParameter("htmlcomment");
    System.out.println(name + " - " +address + " - " +comment);
    out.println( "<div style='background-color:#ffa; padding:20px'>"+name+"   "+address+"  "+comment+"</div>" );
    %>
