store3 = new Ext.data.JsonStore({
autoDestroy: true,
totalProperty : "totle",
url: "service.do",
storeId: "myStore",

fields : [ "id", "name", "pw" ]
});

var pagingToolbar = new Ext.PagingToolbar({
emptyMsg : "没有数据",
displayInfo : true,
displayMsg : "显示从{0}条数据到{1}条数据，共{2}条数据",
store : store3,
pageSize : 50
});

var grade = new Ext.grid.GridPanel({
title : "数据列表",
store : store3,
height : 300,
bbar : pagingToolbar,
columns : [ {
header : "id",
dataIndex : "id",
