简介

抽象工厂模式不直接生成实例，而是用于对产品类簇的创建

ES6

class User {
  constructor(name, role, pages) {
    this.name = name;
    this.role = role;
    this.pages = pages;
  }

  weclome() {
    console.log("欢迎回来" + this.name);
  }
  dataShow() {
    throw new Error("抽象方法需要被实现");
  }
}

class SuperAdmin extends User {
  constructor(name) {
    super(name, "superadmin", [
      "home",
      "user-manage",
      "right-manage",
      "news-manage",
    ]);
  }
  dataShow() {
    console.log("superadmin-datashow");
  }

  addRight() {}

  addUser() {}
}

class Admin extends User {
  constructor(name) {
    super(name, "admin", ["home", "user-manage", "news-manage"]);
  }

  dataShow() {
    console.log("admin-datashow");
  }

  addUser() {}
}

class Editor extends User {
  constructor(name) {
    super(name, "editor", ["home", "news-manage"]);
  }

  dataShow() {
    console.log("editor-datashow");
  }
}

function getAbstractUserFactory(role) {
  switch (role) {
    case "superadmin":
      return SuperAdmin;
    case "admin":
      return Admin;
    case "editor":
      return Editor;
    default:
      throw new Error("参数错误");
  }
}

let UserClass = getAbstractUserFactory("admin");

let user = new UserClass("kerwin");
