Store和SimpleStore的比较

//创建一个Store

var data = [
  ['1','name1','female','10'],
  ['2','name5','male','14'],
  ['3','name2','female','23'],
  ['4','name3','male','15'],
  ['5','name4','female','22']
 ];

var recordType = new Ext.data.Record.create([
   {name:'id',type:'string'},
   {name:'name',type:'string'},
   {name:'sex',type:'string'},
   {name:'age',type:'int'}

]);

var store = new Ext.data.Store({
         proxy:new Ext.data.MemoryProxy(data),
         //url:'text.xml',
         reader:new Ext.data.XmlReader({
               //指定记录的标签
               record: 'salary'
           }, recordType),
           //指定排序字段
           sortInfo:{field:'id', direction:'ASC'}        
        });

 

//创建一个SimpleStore

var simpleStore = new Ext.data.SimpleStore({
 fields:[{
  name:'id',type:'string'
 },{
  name:'name',type:'string'
 },{
  name:'sex',type:'string'
 },{
  name:'age',type:'int'
 }],
 data:data
});

//simpleStore.loadData(data);
