ES6 迭代类方法 [英] ES6 Iterate over class methods

问题描述

给定这个类；我将如何迭代它包含的方法?

Given this class; how would i iterate over the methods that it includes?

class Animal {
    constructor(type){
        this.animalType = type;
    }
    getAnimalType(){
        console.log('this.animalType: ', this.animalType );
    }
}

let cat = window.cat = new Animal('cat')

我尝试了以下但没有成功:

What I have tried is the following with no success:

for (var each in Object.getPrototypeOf(cat) ){
    console.log(each);
}

推荐答案

您可以使用 Object.getOwnPropertyNames:

Object.getOwnPropertyNames( Animal.prototype )
// [ 'constructor', 'getAnimalType' ]
