建造者模式

建造者模式

建造者模式主要是将构建层与表示层分离，一种模块化的思想，使单个模块可以高效灵活的复用，但这种拆分同样增加了一定复杂度

实例：招聘简历

创建一个人类的类

const Human = function(param){
    this.skill = param && param.skill || "保密"
    this.hobby = param && param.hobby || "保密"
}

Human.prototype = {
    getSkill: function(){
        return this.skill
    },
    getHobby: function(){
        return this.hobby
    }
}

创建一个姓名的类

const Named = function(name){
    ((name)=>{
        this.wholeName = name
        if(name.indexOf(" ") > -1){
            this.FirstName = name.slice(0, name.indexOf(" "))
            this.LastName = name.slice(name.indexOf(" "))
        }
    })(name)
}

创建一个职位的类

const Work = function(work){
    ((work)=>{
        switch(work){
            case "code":
                this.work = "工程师"
                this.workDescript = "description"
            case "UE":
                this.work = "设计师"
                this.workDescript = "description"
            case "teach":
                this.work = "教师"
                this.workDescript = "description"
            default:
                this.work = work
                this.workDescript = "description"
        }
    })(work)
}
// 更换期待的职位
Work.prototype.changeWork = function(work){
    this.work = work
}
// 更换描述
Work.prototype.changeDescript = function(descript){
    this.workDescript = descript
}

创建应聘者类

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