Javascript 如何将函数从主对象动态继承到其他对象？,javascript,object,inheritance,Javascript,Object,Inheritance,在这种情况下，我想创建动态的新对象（某些动物），例如对象“游戏”下的青蛙。在Game.frog里面我想从Game继承函数init到frog 因此，frog也将具有函数init 所有其他动物将克隆函数init Game.frog.init(), Game.lion.init() ...... Game.n...int() 动物将如下所示非常感谢你的帮助 Game.frog = { init: function(){ this.property1 = somethin

因此，frog也将具有函数init
所有其他动物将克隆函数init

 Game.frog.init(), Game.lion.init() ...... Game.n...int()

动物将如下所示
非常感谢你的帮助
Game.frog = {
    init: function(){
        this.property1 = something;
        this.property2 = something;
        this.property3 = something;
        this.property1000 = something;
    }

-JSFIDLE演示
//  
为什么不创建一个动物功能，然后为您的每一个小动物实例化：
function Animal() {
    self = this;
    self.init = function() {
        self.property1 = 1;
        self.property2 = 2;
        self.property3 = 3;
        self.property1000 = 1000;
    }
}

var frog = new Animal();
frog.init();

也可以读一读：了解JS继承模式。你应该重新考虑你试图访问“动物”的方式。。。
试试这个：
window.onload = function () {

    function Animal(name) {
      this.name = name;
      this.property1 = 1;
      this.property2 = 2;
      this.property3 = 3;
      this.property1000 = 1000;
    }

    function Game() {
      this.animals = {};

      this.addAnimal = function (animalName) {
        this.animals[animalName] = new Animal(animalName);

      };
    }


    var game = new Game();

    game.addAnimal('frog');
    game.addAnimal('lion');
    game.addAnimal('cat');

    alert(game.animals.frog.name +"; " + game.animals.frog.property1 +"; " + game.animals.frog.property2);
  };

我想你应该写：this.gameanies[i].init=this.init；因此没有（）调用该函数
