工厂模式创建对象和构造函数 原型模式

1.工厂模式

    function Person(name,age,job){
                      //创建对象
                      var o = {};
                       o.name = name;
                       o.age = age;
                       o.job = job;
                       
                       o.showName = function(){
                                    alert(this.name);
                      };
                        .showName = function(){
                                     alert(this.age);
                      };
                       .showName = function(){
                                     alert(this.age)
                       };
                        return o;
    }
    var Tom = Person('tom',18,'程序员');
    Tom.showName();

2.构造函数

    function Person(name,age,job){
                       this.name = name;
                       this.age = age;
                       this.job = job;
                       
                       this.showName = function(){
                                    alert(this.name);
                      };
                       this .showAge = function(){
                                     alert(this.age);
                      };
                       this.showJob = function(){
                                     alert(this.age)
                       };
                        return o;
    }
    var Bob = new Person('bob',18,'产品');
    Bob.showName();

3.原型模式

     function Person(name,age,job){
                       this.name = name;
                       this.age = age;
                       this.job = job;
    }
    //prototype原型
    person.peototype.showName = function(){
                alert(this.name);
    };
            person.peototype.showAge = function(){
                alert(this.age);
    };
    person.peototype.showJob = function(){
                alert(this.job);
    };
    var Lucy = new person('Lucy',19,'测试鼠');
    alert(luck.showName());
