Without further ado, I will just post the code for you. The specific code is as follows:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>jQuery form插件的使用--处理server返回的JSON， XML，HTML数据</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<script src="jquery-1.3.1.js" type="text/javascript"></script>
<script src="jquery.form.js" type="text/javascript"></script>
<script type="text/javascript"> 
// json
$(document).ready(function() { 
$('#myForm').ajaxForm({ 
// 声明 服务器返回数据的类型.
dataType: 'json', 
success: processJson 
}); 
});
function processJson(data) { 
// 'data'是一个json对象，从服务器返回的.
$('#jsonOut').html(data.name + " "+data.address + " "+data.comment); 
}
// xml 
$(document).ready(function() { 
$('#xmlForm').ajaxForm({ 
// 声明 服务器返回数据的类型.
dataType: 'xml', 
success: processXml 
}); 
}); 
function processXml(responseXML) { 
// 'responseXML' 是一个XML的文档 ，从服务器返回的.
var name = $('name', responseXML).text(); 
var address = $('address', responseXML).text(); 
var comment = $('comment', responseXML).text(); 
$('#xmlOut').html(name + " "+address + " "+comment); 
}
// html 
$(document).ready(function() { 
$('#htmlForm').ajaxForm({ 
// 用服务器返回的数据 更新 id为 htmlcssrain 的内容.
target: '#htmlOut', 
success: function() { 
$('#htmlOut').fadeIn('slow'); 
} 
}); 
});
</script> 
</head>

</html>

Create a new json.jsp file:

<%@ 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+ "' }" );
%>

New xml.jsp file:

<%@ 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("<&#63;xml version=\"1.0\" encoding=\"UTF-8\"&#63;>");
out.print("<root>");
out.print("<name>"+name+"</name>");
out.print("<address>"+address+"</address>");
out.print("<comment>"+comment+"</comment>");
out.print("</root>");
%>

Create a new html.jsp file:

<%@ 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>" );
%>

The above is the use of the jQuery form plug-in that the editor shared with you to process the JSON, XML, and HTML data returned by the server. I hope it will be helpful to everyone.

Python vs. JavaScript: A Comparative Analysis for DevelopersMay 09, 2025 am 12:22 AM

The main difference between Python and JavaScript is the type system and application scenarios. 1. Python uses dynamic types, suitable for scientific computing and data analysis. 2. JavaScript adopts weak types and is widely used in front-end and full-stack development. The two have their own advantages in asynchronous programming and performance optimization, and should be decided according to project requirements when choosing.

Python vs. JavaScript: Choosing the Right Tool for the JobMay 08, 2025 am 12:10 AM

Whether to choose Python or JavaScript depends on the project type: 1) Choose Python for data science and automation tasks; 2) Choose JavaScript for front-end and full-stack development. Python is favored for its powerful library in data processing and automation, while JavaScript is indispensable for its advantages in web interaction and full-stack development.

Python and JavaScript: Understanding the Strengths of EachMay 06, 2025 am 12:15 AM

Python and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.
