使用JSON创建对象

    function sayLoudly() {
        alert(this.firstName.toUpperCase());
    }
    var newObject = {//每个子对象间用,分割
        firstName : "frank",
        sayName : function() {
            alert(this.firstName)
        },
        sayLoudly : sayLoudly,
        LastName : {
            lastName : "Zammetti",
            sayName : function() {
                alert(this.lastName);
            }
        }
    };
    newObject.LastName.sayName();
