使用构造函数获取已定义对象的名称 [英] Getting the name of a defined object with a constructor

问题描述

我试图获取对象的名称，并在定义后将其放入数组中，我尝试执行此代码，但是名称最终变为 undefined

I'm trying to get the name of an object and put it in an array after it's defined, I tried doing this code, but the name ended up being undefined any help?

function command(category, help, callback) {
  this.category = category;
  this.help = help;
  this.do = callback;

  cmndlist[category].push(this.name);
}; 

推荐答案

对象没有名称或 name 属性（除非您自己添加一个）。如果您引用的是引用对象的变量名，则无法访问。

Objects do not have a name or name property (unless you add one yourself). If you're referring to the variable name that references the object, that is not possible to access.
