ext的几种store定义和赋值

来源：互联网发布：愿你知我心编辑：程序博客网时间：2024/04/29 02:05

1. 对应gridpanel的store定义：

var store = new Ext.data.Store({proxy: new Ext.data.HttpProxy({method: 'post',url: ''}),reader: new Ext.data.JsonReader({totalProperty : 'TOTALCOUNT',root : 'ROOT'}, ['id', 'name', 'parentName', 'title'])//reader: new Ext.data.JsonReader({}, [//'id', 'name', 'parentName', 'title'//])});

如果返回的json数据没有分页信息，reader使用被注释的；

2. SimpleStore，常量store定义

new Ext.data.SimpleStore({fields : ['name'],data : [['aaaa']   ]})

3. Ext.data.ArrayStore

var searchStore = new Ext.data.ArrayStore({fields: ['name'],idIndex: 1});searchStore.removeAll();searchStore.add(new Ext.data.Record({name: 'code2'}));searchStore.add(new Ext.data.Record({name: 'code3'}));searchStore.add(new Ext.data.Record({name: 'code4'}));

4. 通过Ext.data.Record给store定义字段：

var rt = Ext.data.Record.create([    {name: 'fullname'},    {name: 'first'}]);var myStore = new Ext.data.Store({    reader: new Ext.data.ArrayReader(        {            idIndex: 0  // id for each record will be the first element        },        rt     )});

5. 通过常量数组给store赋值：

var myData = [    [1, 'Fred Flintstone', 'Fred'],  // note that id for the record is the first element    [2, 'Barney Rubble', 'Barney']];myStore.loadData(myData);

6. store通过Ext.data.XmlReader接收xml格式数据

var store= new Ext.data.Store({url: '',reader: new Ext.data.XmlReader({totalProperty: 'total',record: 'unit',id: 'code2'}, [{name: 'code2', mapping: 'code2'}, 'code3', 'code4'])});

从后台返回的数据需要加上一句：

response.setContentType("text/xml; charset=UTF-8");
