ES6迭代类方法 [英] ES6 Iterate over class methods
本文介绍了ES6迭代类方法的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
class Animal {
constructor(type){
this.animalType = type;
}
getAnimalType(){
console.log('this.animalType:',this.animalType);
}
}
let cat = window.cat = new Animal('cat')
我尝试过的以下内容没有成功:
for(var each在Object.getPrototypeOf(cat)){
console.log(each);
}
解决方案
您可以使用 Object.getOwnPropertyNames 原型:
Object.getOwnPropertyNames(Animal.prototype)
// ['constructor','getAnimalType']
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')
What I have tried is the following with no success:
for (var each in Object.getPrototypeOf(cat) ){
console.log(each);
}
解决方案
You can use Object.getOwnPropertyNames on the prototype:
Object.getOwnPropertyNames( Animal.prototype )
// [ 'constructor', 'getAnimalType' ]
