特點(diǎn)：工廠模式的特點(diǎn)是創(chuàng)建的結(jié)果都是一個(gè)完整的個(gè)體，我們對(duì)創(chuàng)建過(guò)程不得而知，我們只了解得到的創(chuàng)建結(jié)果對(duì)象。而建造者模式中我們關(guān)心的是對(duì)象的創(chuàng)建過(guò)程，因此我們通常將創(chuàng)建對(duì)象的類模塊化，這樣使被創(chuàng)建的類的每一個(gè)模塊都可以得到靈活的運(yùn)用與高質(zhì)量的復(fù)用。

實(shí)現(xiàn)：創(chuàng)建一位應(yīng)聘者，分別有基礎(chǔ)信息類（技能和愛(ài)好），姓名解析類（分隔FirstName和LastName）和期望職位類（職位名稱，職位描述）

Human類

    var Human = function(param) {
      // 技能
      this.skill = param && param.skill || '保密'
      // 興趣愛(ài)好
      this.hobby = param && param.hobby || '保密'
    }
    Human.prototype = {
      getSkill: function() {
        return this.skill
      },
      getHobby: function() {
        return this.hobby
      }
    }

姓名處理類

    var Named = function(name) {
      var that = this;
      (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)
    }

職位處理類

    var Work = function(work) {
      var that = this;
      (function(work, that){
        switch(work) {
          case 'code':
            that.work = '工程師'
            that.workDescript = '每天擼代碼'
            break
          case 'UI':
            that.work = '設(shè)計(jì)師'
            that.workDescript = '畫畫畫'
            break
          default:
            that.work = work
            that.workDescript = '不知道這個(gè)職業(yè)'
        }
      })(work, that)
    }
    Work.prototype.changeWork = function(work) {
      this.work = work
    }
    Work.prototype.changeDescript = function(setence) {
      this.workDescript = setence
    }

應(yīng)聘者創(chuàng)建類

    var Person = function(name, work) {
      var _person = new Human()
      _person.name = new Named(name)
      _person.work = new Work(work)
      return _person
    }

執(zhí)行結(jié)果

    var zhengguorong = new Person('zheng guorong', 'code')
    console.log(zhengguorong.skill) // 保密
    console.log(zhengguorong.name.FirstName) // zheng
    console.log(zhengguorong.work.workDescript) // 每天擼代碼
    zhengguorong.work.changeWork('UI')
    console.log(zhengguorong.work.work) // UI
