Ext.define('SmartPhone', {

config: {

hasTouchScreen: false,//有触摸屏

operatingSystem: 'Other',//操作系统

price: 500//价格

},

constructor: function(cfg) {

this.initConfig(cfg);

}

});

//iPhone手机

var iPhone = new SmartPhone({

});

var develop = new Developer();

develop.say("text");

alert("测试　static");

//测试　static

//构造一台计算机

Ext.define('Computer', {

statics: {
