【Factory】最简单的工厂模式

patterns-factory-simple.js

var BasketBall = function () { /* ... */};
var FootBall = function () { /* ... */};
var Tennis = function () { /* ... */};

// 运动工厂
var sportsFactory = function (name) {
  switch(name) {
    case 'NBA':
      return new BasketBall();
    case 'WorldCup':
      return new FootBall();
    case 'ATP':
      return new FootBall();
  }
}

// 另外一种工厂模式
function createBook(name, time, type) {
  // 创建一个对象，并对对象拓展属性和方法
  var o = new Object();
  o.name = name;
  o.type = type;
  o.time = time;
  o.getName = function () {
    console.log(this.name);
  }
  return o;
}
