对象的定义

ECMA-262把对象定义为:“无序属性的集合，其属性可以包含基本值、对象或者函数。”

Object方式创建对象：

var person = new Object();

person.name = "Nicholas";

person.age = 29;

person.job = "Software Engineer";

person.sayName = function(){

alert(this.name);

};

字面量方式创建对象：

var person = {

name: "Nicholas",

age: 29,

job: "Software Engineer",

sayName: function(){

alert(this.name);

}

};
