//加载数据

store.load();

//添加数据

store.add({loginname:‘administrator.com‘,ip:‘192.168.1.8‘});

//读取数据

store.each(function(record){

    console.info(record.get(‘loginname‘));

    alert(record.get(‘loginname‘));

});

//过滤

//store.filter("loginname", /\.com$/);根据单个属性域(field)过滤:

store.filter([

              {property: "loginname", value: /\.com$/},

              {filterFn: function(item) { return item.get("ip") == ‘192.168.1.5‘; }}

]);

//查找某条记录

var record = store.find(‘loginname‘,‘guest‘);

//获取store中第一条记录的快捷方法.

var record = store.first();

//获取指定index处的记录

var record = store.getAt(2);

//获取store中记录的数量

var count = store.getCount;

//获取store中最后一条记录的快捷方法

var record = store.last();
