ES6—45：子类对父类方法的重写

飞奔的炮台

代码示例

class Father {
  constructor(name,price) {
    this.name = name;
    this.price = price;
  };
  call() {
    console.log("手机可以打电话！");
  };
};
class Son extends Father {
  constructor(name,price,color,size) {
    super(name,price);
    this.color = color;
    this.size = size;
  };
  photo() {
    console.log("手机可以拍照");
  };
  call() {
    console.log("这是子类的函数");
  };
};
const xiaomi = new Son("红米K30","4999","荣耀黑","6.7英寸");
console.log(xiaomi);
xiaomi.call();
