javascript设计模式

1工厂模式

工厂模式是软件领域一种广为人知的设计模式废话少说直接贴代码

 1 function createPerson(name,age,job){
 2     var 0 = {};
 3     o.name = name;
 4     o.age = age;
 5     o.job = job;
 6     o.sayName = function(){
 7         alert(this.name)
 8     };
 9     return o;
10 }
11 var person1 = createPerson("sunhaixun",29,"web");
12 var person2 = createPerson("kk",15,"doctor");
13 person1.sayName();
14 person2.sayName();

2.构造函数模式

 1 function Person(name,age,job){
 2     this.name = name;
 3     this.age = age;
 4     this.job = job;
 5     this.sayName = function(){
 6         alert(this.name);
 7    };
 8 }
 9 var person1 = newPerson("sunhaixun",29,"web");
10 var person2 = newPerson("zhanghaiwei",20,"doctor");
11 person1.sayName();
12 person2.sayName();
