此JSP页面用于修改产品的ID、名称、现价，并通过AJAX与后台交互完成修改操作。
啥也不说了，直接上例子！！！！
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%String name = new String(request.getParameter("name").getBytes("ISO-8859-1"),"utf-8");
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
