1、将父对象作为新对象的原型

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;
			else
				return this.name;
		}
}
var twoDShape = object(shape);
twoDShape.name = "2 D Shape";
alert(twoDShape.toString());

function Shape(id) {
	this.id = id;

}
Shape.prototype.name = 'shape';
Shape.prototype.toString = function(){return this.name;};

function Triangle() {
	Shape.apply(this, arguments);//原生属性继承
}
