设计模式(三) 建造者模式

var human = function(hobby){
	this.hobby = hobby;
}
human.prototype = {
	getHobby: function(){
		return this.hobby;
	}
}
//实例化姓名类
var named = function(name){
	var that = this;
	//构造器
	(function(name, that){
		that.wholeName = name;
	})(name, that);
}
named.prototype.xx = function(){}
var person = function(name){
	var _person = new Human();
	_person.name = new named(name);
	//若有其他类可继续添加……
	return _person;
}
var x1 = new person('Bob');
//通过对创建对象的类的模块化，使得其可以得到灵活运用，高度复用，但也会增加结构的复杂度
