本文介绍了一种使用JSON字符串和JSON对象在JSP页面中动态展示内容的方法，包括如何从JSON文件中解析数据并将其插入到HTML元素中。重点在于解释了JSON与JavaScript在页面动态更新中的应用。

<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%>
 <%
 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>
 	<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">
 	<!--
 	<link rel="stylesheet" type="text/css" href="styles.css">
 	-->
 	<script type="text/javascript" src="js/json.js"></script>
   </head>
   
 
   <body >
     <span id="name"></span><br>
     <span id="discription"></span>
     <hr>
     <span id="name1"></span><br>
     <span id="discription1"></span>
     <script type="text/javascript">
 	  
 	  var data='{"name":"肖永健","sex":"男"}'; 
 	  var dataList='[{"name":"肖永健","sex":"男"},{"name":"林文娜","sex":"女"}]';
 	  var obj =JSON.parse(data);
 	  var obj1 = JSON.parse(dataList);
 	  document.getElementById("name").innerHTML =obj.name;
 	  document.getElementById("discription").innerHTML = obj.sex;
 	  document.getElementById("name1").innerHTML =obj1[0].name;
 	  document.getElementById("discription1").innerHTML =obj1[1].name;
     </script>
   </body>
 </html>

输出结果：
