考虑到这一节课;我将如何迭代其中包含的方法?
class Animal {
constructor(type){
this.animalType = type;
}
getAnimalType(){
console.log('this.animalType: ', this.animalType );
}
}
let cat = window.cat = new Animal('cat')
我尝试过的以下操作均未成功:
for (var each in Object.getPrototypeOf(cat) ){
console.log(each);
}
最佳答案
您可以在原型上使用Object.getOwnPropertyNames:
Object.getOwnPropertyNames( Animal.prototype )
// [ 'constructor', 'getAnimalType' ]
