1.这是我的界面(代码如下)：
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <html> <head> <link rel="stylesheet" type="text/css" href="resources/css/ext-all.css" /> <script type="text/javascript" src="extjs/ext-base.js"></script> <script type="text/javascript" src="extjs/ext-all.js"></script> <script type="text/javascript" src="extjs/ext-lang-zh_CN.js"></script> <script type="text/javascript" src="js/jss.js"></script> <title>this is jsp</title> </head> <body> <div id="grid"></div> </body> </html> 2.数据来源（来自jsp界面）:<%@ 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> <title>My JSP 'aaa.jsp' starting page</title> </head> <body> <% String start = request.getParameter("start"); String limit = request.getParameter("limit"); String json=""; try { int index = Integer.parseInt(start); int pageSize = Integer.parseInt(limit); json = "{totalProperty:100,root:["; for (int i = index; i < pageSize + index; i++) { json += "{id:" + i + ",name:'name" + i + "',descn:'descn" + i + "'}"; if (i != pageSize + index - 1) { json += ","; } } json += "]}"; response.getWriter().write(json); System.out.println(json); System.out.println(index); System.out.println(pageSize); } catch(Exception ex) { } %> </body> </html> 数据显示json格式：{totalProperty:100,root:[{id:0,name:'name0',descn:'descn0'},{id:1,name:'name1',descn:'descn1'},{id:2,name:'name2',descn:'descn2'},{id:3,name:'name3',descn:'descn3'},{id:4,name:'name4',descn:'descn4'},{id:5,name:'name5',descn:'descn5'},{id:6,name:'name6',descn:'descn6'},{id:7,name:'name7',descn:'descn7'},{id:8,name:'name8',descn:'descn8'},{id:9,name:'name9',descn:'descn9'}]} 3.js的写入： Ext.onReady(function(){ var cm = new Ext.grid.ColumnModel([ {header:"编号",dataIndex:"id",sortable:true}, {header:"名称",dataIndex:"name",sortable:true}, {header:"描述",dataIndex:"descn",sortable:true} ]); var dds = new Ext.data.Store({ proxy: new Ext.data.HttpProxy({url:'aaa.jsp'}), reader: new Ext.data.JsonReader({ totalProperty: 'totalProperty', root: 'root' }, [ {name: "id"}, {name: "name"}, {name: "descn"} ]) }); var grid = new Ext.grid.GridPanel({ el: "grid", ds: dds, cm: cm, bbar: new Ext.PagingToolbar({ pageSize:10, store:dds, displayInfo:true, displayMsg:'显示{0}到{1}条记录，总共{2}条记录', emptyMsg:'没有记录' }) }); grid.render(); dds.load({params:{start:0,limit:10}}); }); 问题：1.为什么我的界面显示不出来数据？？用firebug调试可以得到jsp界面的数据 2.希望大家能给出些详细的解决方案。 谢谢大家了 声明：ITeye文章版权属于作者，受法律保护。没有作者书面许可不得转载。
