ts重点学习128-混入笔记

// 对象混入
// let nameObj = {name: "王楚然"};
// let ageObj = {age: 18};
 
// // 需求：想让nameObj也拥有 age这个属性
// Object.assign(nameObj, ageObj);
// console.log(nameObj);
// console.log(ageObj);
 
 
 
 
 
// 类混入
 
class Name {
  name: string = "毛晓彤";
  getName():void {
    console.log("我是毛晓彤");
  }
}
 
class Age {
  age: number = 18;
  getAge():void {
    console.log("我今年18岁了");
    
  }
}
 
// class Person extends Name, Age {}
 
class Person implements Name, Age {
  name: string;
  age: number;
  getAge: () => void;
  getName: () => void;
}
 
function Mixins(target: any, from: any[]) {
  from.forEach(item => {
    Object.getOwnPropertyNames(item.prototype).forEach(name => {
      target.prototype[name] = item.prototype[name]
    })
  })
}
 
Mixins(Person, [Name, Age])
 
let p = new Person()
p.getAge()
p.getName()
