本文介绍了一个结合JSP和Ajax技术实现的在线编辑器示例。该示例通过客户端JavaScript与服务器端Servlet交互，实现了文本的在线编辑功能。文章强调了JSP页面编码设置为UTF-8的重要性，并指出了Ajax请求采用POST方式时服务器端处理的方法。

1，注意,保证JSP页面编码方式是"UTF-8"

2, 注意,InPlaceEditor Ajax 请求形式为"POST",应注意服务器端处理请求响应方法为"doPost"

客户端示例代码如下：

<%@ 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 'test01.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">  <mce:script type="text/javascript" src="prototype-1.6.0.3.js" mce_src="prototype-1.6.0.3.js"></mce:script> <mce:script type="text/javascript" src="effects.js" mce_src="effects.js"></mce:script> <mce:script type="text/javascript" src="controls.js" mce_src="controls.js"></mce:script> </head> <body> <h2>Script.aculo.us InPlaceEditor</h2> <span id="testdiv">In Place Editor</span> <mce:script type="text/javascript"></mce:script> </script> </body> </html>

使用Servlet处理Ajax响应,服务器端代码如下：

package org.chy.ajax; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.io.PrintWriter; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; public class InPlaceEditor extends HttpServlet { @Override protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html"); response.setCharacterEncoding("UTF-8"); PrintWriter out = response.getWriter(); //打印客户端请求的数据 /* BufferedReader br = new BufferedReader(new InputStreamReader(request.getInputStream())); String line; while((line = br.readLine()) != null){ System.out.println(line); }*/ String value = request.getParameter("value"); System.out.println("value:"+value); String editorId = request.getParameter("editorId"); System.out.println("editorId:"+editorId); out.print(value); out.flush(); out.close(); } }
