JavaScript物件導向編程(11)其他繼承方式,javascript物件導向

1、將父物件作為新對象的原型

function object(o) {var n;function F() {}F.prototype = o;n = new F();n.uber = o;return n;}var shape = {name: 'Shape',toString: function(){if(this.uber)return this.uber.toString() + ', ' + this.name;elsereturn this.name;}}var twoDShape = object(shape);twoDShape.name = "2 D Shape";alert(twoDShape.toString());


2、在子構造器中調用父構造器Parent.apply();並傳遞參數,這樣與父物件的this綁定的屬性同時成為子物件的屬性

function Shape(id) {this.id = id;}Shape.prototype.name = 'shape';Shape.prototype.toString = function(){return this.name;};function Triangle() {Shape.apply(this, arguments);//原生屬性繼承}
