extjs model store学习笔记

// 定义一个Model
Ext.define('MyApp.model.User', {
extend: 'Ext.data.Model',
fields: [
{name: 'name', type: 'string'},
{name: 'age', type: 'int'}
]
});

// 定义一个store
Ext.define('MyApp.store.Users', {
extend: 'Ext.data.Store',
alias: 'store.users',
model: 'MyApp.model.User',
data : [ // Stores can also load data in-line. Internally, Store converts each of the objects we pass in as data into records of the appropriate Model type:
{firstName: 'Seth', age: '34'},
{firstName: 'Scott', age: '72'},
{firstName: 'Gary', age: '19'},
{firstName: 'Capybara', age: '208'}
]
});

var store = Ext.create('Ext.data.ArrayStore', {
// store configs
storeId: 'myStore',
// reader configs
fields: [ // 可以直接定义fields,不必定义model

{name: 'price', type: 'float'},
{name: 'change', type: 'float'},
{name: 'pctChange', type: 'float'},
