分即是合 - 建造者模式

· Yin灏

建造者模式：将一个复杂对象的构建层与其表示层相互分离，同样的构建过程可采用不同的表示。

// 创建一位人类
var Human = function (param) {
  // 技能
  this.skill = (param && param.skill) || "保密";
  // 兴趣爱好
  this.hobby = (param && param.hobby) || "保密";
};

// ******************
// 人类原型方法
Human.prototype = {
  getSkill: function () {
    return this.skill;
  },
  getHobby: function () {
    return this.hobby;
  },
};

// ******************
// 实例化姓名类
var Named = function (name) {
  var that = this;
  // 构造器
  // 构造函数解析姓名的姓与名
  (function (name, that) {
    that.wholeName = name;
    if (name.indexOf(" ") > -1) {
      that.FirstName = name.slice(0, name.indexOf(" "));
      that.secondName = name.slice(name.indexOf(" "));
    }
  })(name, that);
};

// ******************
// 实例化职位类
var Work = function (work) {
  var that = this;
  // 构造器
  // 构造函数中通过传入的职位特征来设置相应职位以及描述
  (function (work, that) {
    switch (work) {
      case "code":
        that.work = "工程师";
        that.workDescript = "每天沉醉于编程";
        break;
      case "UI":
      case "UE":
        that.work = "设计师";
        that.workDescript = "设计更似一种艺术";
        break;
      case "teach":
        that.work = "教师";
        that.workDescript = "分享也是一种快乐";
        break;
      default:
        that.work = work;
        that.workDescript = "对不起，我们还不清楚您所选择职位的相关描述";
    }
  })(work, that);
};

// ******************
// 更换期望的职位
Work.prototype.changeWork = function (work) {
  this.work = work;
};
// 添加对职位的描述
Work.prototype.changeDescript = function (setence) {
  this.workDescript = setence;
};

创建一位应聘者

var Person = function (name, work) {
  // 创建应聘者缓存对象
  var _person = new Human();
  _person.name = new Named(name);
  _person.work = new Work(work);
  return _person;
};

var person = new Person("xiao ming", "code");
console.log(person.skill); // '保密'
console.log(person.name.FirstName); // 'xiao'
console.log(person.work.work); // '工程师'
console.log(person.work.workDescript); // '每天沉醉于编程'
person.work.changeDescript("更改一下职位描述！");
