javascript常用创建对象的方式

1.工厂方式

//定义

var oCar = new Object();

oCar.color = “red”;

oCar.doors = 4;

oCar.showColor = function() {

alert(this.color);

}

2.造函数

//定义

function Car(color, doors) {

this.color = color;

this.doors = doors;

this.showColor = function() {

alert(this.color);

};

3.混合的构造函数/原型模式

function Car(color,doors)

{

this.color=color;

this.doors=doors;

this.drivers=new Array(“Tom”,”Jerry”);

}

Car.prototype.showColor=function(){

alert(this.color);

}
