<body>
<script>
var Person = function(name,age){
this.name = name;
this.age = age;
};
Person.prototype={
setName:function(name){
this.name = name;
return this
},
setAge:function(age){
this.age = age;
return this
},
getName:function(){
return this.name;
},
getAge:function(){
return this.age;
}
};
var p = new Person();
p.setName("lili").setAge("11");
console.info(p.getName());
console.info(p.getAge());
