js创建object对象主要有以下四种方法：
使用new操作符后跟Object构造函数
var person = new Object();//可以写成 var person = {};
person.name = "kate";
person.age = 18;
使用“对象字面量”表示法
var person = {
name : "kate",
age:18
};
工厂模式方法
var createPerson = function(name,age,job){
var person = new Object();
person.name = name;
person.age = age;
person.job = job;
person.sayName = function(){
alert(person.name);
}
return person;
}
var person1 = createPerson("zh","62","Doctor");
person1.sayName();
构造函数模式方法
function Person(name,age,job){
this.name = name;
this.age = age;
this.job = job;
this.sayName = function(){
alert(this.name);
};
};
var person1 = new Person("zhou",23,"test");
person1.sayName();
