创建对象之间的链接

Question

我正在学习 JavaScript，我创建了三个具有一些属性的不同对象：Person、House 和 Car。let House = function(city, postalCode, street, streetNumber){  this.city = city;  this.postalCode = postalCode;  this.street = street;  this.streetNumber = streetNumber;  return {    getAddress: function() {      return {        'address': {          'city': city,          'postalCode': postalCode,          'street': street,          'streetNumber': streetNumber        }      };    }  };};let Person = function(name, surname, yearOfBirth, monthOfBirth, dayOfBirth, bornCity, employment){  this.name = name;  this.surname = surname;  this.yearOfBirth = yearOfBirth;  this.monthOfBirth = monthOfBirth;  this.dayOfBirth = dayOfBirth;  this.bornCity = bornCity;  this.employment = employment;  return {    getFullPerson: function() {      return {          'personalInformation': {            'name': name,            'surname': surname,            'dateOfBirth': {              'year': yearOfBirth,              'month': monthOfBirth,              'day': dayOfBirth            },            'bornCity': bornCity          },          'employment': employment,          'home': getAddress(), // pseudocode          'car': getCar() // pseudocode      };    }  };};我想在这些对象之间创建链接，因为我需要调用，例如，谁住在房子里，反之亦然；但我不清楚如何做到这一点。

Answer 1

这是一个方法：

let House = function(city, postalCode, street, streetNumber){

  this.city = city;

  this.postalCode = postalCode;

  this.street = street;

  this.streetNumber = streetNumber;

  return {

    getAddress: function() {

      return {

        'address': {

          'city': city,

          'postalCode': postalCode,

          'street': street,

          'streetNumber': streetNumber

        }

      };

    }

  };

};

let Person = function(name, surname, yearOfBirth, monthOfBirth, dayOfBirth, bornCity, employment, house, car){

  this.name = name;

  this.surname = surname;

  this.yearOfBirth = yearOfBirth;

  this.monthOfBirth = monthOfBirth;

  this.dayOfBirth = dayOfBirth;

  this.bornCity = bornCity;

  this.employment = employment;

  this.house = house;

  this.car = car;

  return {

    getFullPerson: function() {

      return {

          'personalInformation': {

            'name': name,

            'surname': surname,

            'dateOfBirth': {

              'year': yearOfBirth,

              'month': monthOfBirth,

              'day': dayOfBirth

            },

            'bornCity': bornCity

          },

          'employment': employment,

          'home': (house ? house.getAddress() : null), // pseudocode

          'car': (car ? car.getCar() : null)  // pseudocode

      };

    }

  };

};

let house1 = new House('city', 'postalCode', 'street', 'streetNumber');

let person1 = new Person('person', '1', 2020, 1, 1, 'bornCity', 'employment', null, null);

let person2 = new Person('person', '2', 2020, 1, 1, 'bornCity', 'employment', house1, null);

console.log(person1.getFullPerson());

console.log(person2.getFullPerson());

创建您想要与 关联的任何House或对象。然后，您可以选择在创建每个 时传入或对象。每个或对象也将在该对象内具有可用的功能。CarPersonhomecarPersonhomecarPerson

Answer 2

据我所知，您希望在 Person 对象中引用一个人的房屋和汽车。因此，要使其工作，您唯一需要做的就是将 House 和 Car 对象传递给 Person：

let Person = function (

  name,

  surname,

  yearOfBirth,

  monthOfBirth,

  dayOfBirth,

  bornCity,

  employment,

  home,

  car

) {

  this.name = name

  this.surname = surname

  this.yearOfBirth = yearOfBirth

  this.monthOfBirth = monthOfBirth

  this.dayOfBirth = dayOfBirth

  this.bornCity = bornCity

  this.employment = employment

  this.home = home

  this.car = car

  return {

    getFullPerson: function () {

      return {

        personalInformation: {

          name: name,

          surname: surname,

          dateOfBirth: {

            year: yearOfBirth,

            month: monthOfBirth,

            day: dayOfBirth,

          },

          bornCity: bornCity,

        },

        employment: employment,

        home: home.getAddress(),

        car: car.getCar(),

      }

    },

  }

}
