在JavaScript中解构对象时如何绑定方法?

How to bind methods when destructuring an object in JavaScript?

const person = {
  getName: function() {
    console.log(this);
  }
};

var a = person.getName;
var b = person.getName.bind(person);
var {getName: c} = person;

person.getName(); //=> {getName: [Function]}
a();              //=> window or global
b();              //=> {getName: [Function]}
c();              //=> window or global

我希望c在控制台中登录其父"对象{getName: [Function]}.

I want c to log in the console its "parent" object {getName: [Function]}.

在 destructuring 行中解构对象时，是否有任何方法可以绑定所有方法?

Is there any way to bind all methods when destructuring an object in one destructuring line?

推荐答案

不，没有办法.与对象分离的功能将失去原始上下文.而且JavaScript中的销毁没有语法可以即时处理提取的值.

No, there is no way. Functions detached from objects lose the original context. And destructing in JavaScript has no syntax to do something with extracted values on the fly.
