js中的继承

 <script>
       //js中的继承
       function Animal(){
           this.kind = "animal";
       }
       Animal.prototype.type = "water";
       //绑定构造函数，原型中的属性和方法不会被继承。
       function Cat(Name,Color){
           this.Name = Name;
           this.Color = Color;
           Animal.apply(this.arguments);
       }
       var cat = new Cat("tom","watth");
       console.log(cat);
       
       //原型指向父类对象,继承父类中的所有属性和方法，包括原型中的内容
       function Animal(){
           this.kind = "animal";
       }
       Animal.prototype.type = "water";
       function Cat(name,Color){
           this.name = name;
           this.Color = Color;
       }
       Cat.prototype = new Animal();
       var cat = new Cat("tom","white");
       console.log(cat);
