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();

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());
