原型链实现工厂模式
let UserFactory = function (role) {
if (this instanceof UserFactory) {
let s = new this[role]
return s
} else {
return new UserFactory(role)
}
}
UserFactory.prototype={
SumperAdmin:function (){
this.name="超级管理员"
this.viewPage=['首页','通讯页','发现页','应用数据','权限管理']
},
Admin:function (){
this.name="管理员"
this.viewPage=['首页','通讯页','发现页','应用数据']
},
NormalUser:function (){
this.name="普通用户"
this.viewPage=['首页','通讯页','发现页']
}
}
let superAdmin=UserFactory('SumperAdmin')
console.log(superAdmin.viewPage)
let Admin=UserFactory('Admin')
console.log(Admin.viewPage)
let NormalUser=UserFactory('NormalUser')
console.log(NormalUser.viewPage)
class实现工厂模式
class Animal{
constructor(name){
this.name=name
}
}
class Creator{
create(name){
return new Animal(name)
}
}
let creator=new Creator()
let cat=creator.create('cat')
console.log(cat.name)
let dog=creator.create('dog')
console.log(dog.name)
