JavaScriptのクラス書き方(テンプレート )

よく忘れるのでメモ。

example.js

(function(){

  var Animal;
  Animal = (function(){

    // private method
    var getDistance = function(speed){
      return speed * 60;
    };

    //class変数
    Animal.JapaneseName = "動物";

    //class method
    Animal.called = function(a){
      console.log(a + " called.");
    };

    //constructor
    function Animal(name){
      //private
      this.name = name;
      this.data = {
        weight:1
      }
    }

    //setter
    Animal.prototype.setName = function(name){
      this.name = name;
    };

    //getter
    Animal.prototype.getName = function(){
      return this.name;
    };

    //public method
    Animal.prototype.move = function(speed){
      console.log(this.name + " moved " + getDistance(speed) + " m/h.");
    };

    /* この書き方でも可
     Animal.prototype = {
       getRow: function(){
       },
       setRow: function(r){
       }
     };
     */
    return Animal;
  })();

  //呼び出し
  console.log(Animal.JapaneseName);
  Animal.called("bird");

  var a = new Animal("dog");
  console.log(a.getName());
  a.setName("wolf");
  console.log(a.getName());
  var a2 = new Animal("cat");

  console.log(a.data.weight);

  a.data.weight = 10;
  console.log(a.data.weight);

  a2.data.weight = 5;
  console.log(a2.data.weight);

  a.move(30); // 600 m/h
  a2.move(10); // 1800 m/h

})();
