我数据库里面查询到的是600多条数据，然后返回DataTableToJson格式是：

{"totalCount":677,"items":[{"ID":"00f3b49b-7396-441c-9ef6-7e58a9ec4d09","TYPEID":"2","CARD":"436742121549428911311","BANK":"f6acb4fc-dd75-4d6e-bdcf-c5fce335a913","EXWD":"49c25763-0780-417c-97c7-11f57912a5dc","LXMC":"人员","BANKMC":"建行金支行","EXWDMC":"","COMPANY":"","BANKNAME":"","AREACODE":"","AREANAME":""},{"ID":"00f3b49b-7396-441c-9ef6-7e58a9ec4d09","TYPEID":"2","CARD":"436742121549428911311","BANK":"f6acb4fc-dd75-4d6e-bdcf-c5fce335a913","EXWD":"49c25763-0780-417c-97c7-11f57912a5dc","LXMC":"人员","BANKMC":"建行金支行","EXWDMC":"","COMPANY":"","BANKNAME":"","AREACODE":"","AREANAME":""}]}

这样的。

js获取json：

var store = new Ext.data.Store({
    proxy: new Ext.data.HttpProxy({
        url: "ajax/Bank/SearchBankCardList.ashx"
    }),
    reader: new Ext.data.JsonReader(
        {totalProperty: "totalCount", root: "items"},
        [{name:"ID"},{name:"TYPEID"},{name:"CARD"},{name:"BANKMC"},{name:"LXMC"},{name:"BANK"},{name:"EXWD"},{name:"EXWDMC"},{name:"COMPANY"}
        ,{name:"BANKNAME"},{name:"AREACODE"},{name:"AREANAME"}]
    ),
    listeners: {loadexception: function(){
            error("数据加载错误，请稍候重试...");
        }, load: function(s,records){}
    }
});这样来获取json的，不知道我这格式对不对。总数是600多条我的页面上显示的（当前记录数：1-3 总记录数：3）而且上一页和下一页也不能按显示是灰色的无法翻页，如下图：
