4、装饰器工厂

装饰器工厂可以为装饰器传参

function decro(options:any){
  return (target:any)=>{
    target.prototype.name=options.name;
    target.prototype.getName=()=>{
      console.log(options.name);
    }
  }
}
@decro({
  name:'张三'
})
class Person{
}
let p1:any=new Person()
console.log('name',p1.name);
p1.getName();
