在extjs中，我們用Ext.data.Store類來處理資料，首先需要為它指定url以載入資料的地址，還要指定Ext.data.Reader解碼資料的方式、例子中，伺服器將返回json資料，因而我們需要使用JsonReader讀取資料。

Store不但支援本地排序、篩選和分組，也支援遠端排序、篩選和分組。

var ALLProjectstore = new Ext.data.Store({ proxy: new Ext.data.HttpProxy( { url: "DATA/project/Project.aspx", method: "POST" }), listeners: { load: function () { combo1.setValue(seid); //設定combox初始值 Ext.getCmp('txt').setText(combo1.getRawValue()); //為label動態賦值為“當前專案名稱” } } , reader: new Ext.data.JsonReader( { fields: ["id", "text", "picture"], root: "data", id: "id", totalProperty: "totalCount" }) }); ALLProjectstore.load();

獲取資料的地址為DATA/project/Project.aspx

.aspx中寫成<%@ Page Language="C#" AutoEventWireup="true" CodeFile="GetCustomerInfo.aspx.cs" Inherits="DATA_customer_GetCustomerInfo" %> <%= ParamJSON%>

.cs中寫成using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using Maticsoft.BLL; public partial class DATA_customer_GetCustomerInfo : System.Web.UI.Page { public string ParamJSON = ""; customer bll = new customer(); protected void Page_Load(object sender, EventArgs e) { string project_id = Request.Form["project_id"]; int id = 0; if (project_id != string.Empty) { id = Convert.ToInt32(project_id); } GetOrderJSON("project_id=" + id); } public void GetOrderJSON(string strwhere) { //int id = Convert.ToInt32(Request.Form["id"]); ParamJSON = bll.getCustomerInfo(strwhere); } }
