[Back To Basic] Javascript - 物件建構式(Object Constructor)

使用建構式

function User(name, age, phone) {

    this.name = name;

    this.age = age;

    this.phone = phone;

}

var me = new User('Shawn', 18, '0900123456');

var coworker = new User('Koji', 20, '0911321321');

新增屬性(property)到物件中

me.nationality = 'Taiwan';

新增方法(method)到物件中

coworker.birthYear = function () {

    var year = new Date().getFullYear();

    return year - this.age;

}

新增屬性(property)到建構式中

新增方法(method)到建構式中(只能在一開始的時候給予，不可用新增屬性的方式)

function UserType2(name, age, phone) {

    this.name = name;

    this.age = age;

    this.phone = phone;

    this.nationality = 'Taiwan';

    this.changeName = function (name) {

        this.name = name;

    }

}
