1.使用工厂模式创建对象

function createPerson(name,age,job){ var o = new Object(); o.name = name; o.age = age; o.job = job; o.sayName = function(){  alert(this.name);  }; return o; }var person1 = createPerson('Nike',29,'teacher');var person2 = createPerson('Arvin',20,'student');

2.使用构造函数创建对象

function Person(name,age,job){ this.name = name; this.age = age; this.job = job; this.sayName = function(){ alert(this.name); }; }var person1 = new Person('Nike',29,'teacher');var person2 = new Person('Arvin',20,'student');

3.原型模式创建对象

function Person(){}Person.prototype.name = 'Nike';Person.prototype.age = 20;Person.prototype.jbo = 'teacher';Person.prototype.sayName = function(){ alert(this.name);};var person1 = new Person();person1.sayName();

4.混合构造和原型模式

function Person(name,age,job){ this.name =name; this.age = age; this.job = job;}Person.prototype = { constructor:Person, sayName: function(){ alert(this.name); };}var person1 = new Person('Nike',20,'teacher');

5.动态原型模式

function Person(name,age,job){    this.name=name;    this.age=age;    this.job=job;    if(typeof this.sayName!="function"){        Person.prototype.sayName=function(){            alert(this.name);        };    }}
