第一种：对象字面量的方式

var person = {
                name: "小红",
                age: 22,
                say:function(){
                    console.log(this.name+"今年"+this.age);
                }
            };
            person.say();

第二种：创建Object实例：

var obj = new Object();
            obj.name = "肥狗";
            obj.age = 23;
            obj.say = function(){
                console.log("我是"+this.name+"今年"+obj.age);
            }
            obj.say();

第三种：数构造函数
无参数构造函数

function Person(){
                this.name = "孙悟空";
                this.age = 18;
                this.gender = "男";
                this.sayName = function(){
                    console.log(this.name);
                }
                
            }
            var per = new Person();
            var per2 = new Person();
            console.log(per);
            console.log(per2);

带参数的构造函数

function Person(name,age,hobby){
                this.name = name;
                this.age = age;
                this.hobby = hobby;
                this.sayName = function(){
                    console.log(this.name);
                }
            }
            var people =  new Person("小妹",22,"跑步");
            var people2 =  new Person("小红",22,"跑步");
            var people3 =  new Person("小黄",22,"跑步");
            console.log(people);
            console.log(people2);
            console.log(people3);

第四种：使用工厂方法创建对象

function creatPerson(name,age,tall){
                //创建一个新的对象
                var obj = new Object();
                //向对象中添加属性
                obj.name = name;
                obj.age = age;
                obj.tall = tall;
                obj.sayName = function(){
                    console.log(this.name);
                }
                //将新的对象返回
                return obj;
            }
            var obj2 = creatPerson("孙悟空",18,"1.55米");
            var obj3 = creatPerson("猪八戒",35,"1.57米");
            var obj4 = creatPerson("白骨精",25,"1.50米");
            console.log(obj2);
            console.log(obj3);
            console.log(obj4);

第五种：原型方式创建对象

function Person(name,age){}
            Person.prototype.name = "SF";
            Person.prototype.age = 25;
            Person.prototype.say = function() { 
              alert(this.name+"是我的名字");
            }
            var my = new Person();
            my.say();

第六种：混合方式 （构造函数+原型）创建对象

function Person(name,age) {
                   this.name = name;
                   this.age = age;
                }
                Person.prototype.say = function() { 
                  alert("我是"+this.name+"，今年"+this.age);
                }
                var my = new Person("SF","25");
                my.say();
