创建对象的方法

//创建对象
var o1 = new Object();
o1.property1 = '1';
o1.property2 = '2';

//工厂模式
function createObject(property1,property2){
    var o = new Object();
    o.property1 = property1;
    o.property2 = property2;
    return o;
    }
var o1 = createObject('1','2');

//构造函数模式(构造函数首字母大写)
function O(property1,property2){
    this.property1 = property1;
    this.property2 = property2;
    }
var o1 = new O('1','2');

//原型模式
function O(){
    }
O.prototype.property1 = '1';
O.prototype.property2 = '2';

var o1 = new O();
