使3个数组彼此对应，第一个是对象名称 [英] Make 3 arrays correspond to each other with the first being the object name

问题描述

我目前有多个看起来像这样的对象:

I currently have multiple objects that look like:

let object1 = {
     xyz: 'xyz1',
     arr: []
    },
    object2 = {
     xyz: 'xyz2',
     arr: []
    },
    object3 = {
     xyz: 'xyz3',
     arr: []
    }

这变得非常漫长和多余.无论如何，我可以创建3个数组，例如:

This is getting very long and redundant. Is there anyway I can create 3 arrays like:

let objName = ["object1", "object2", "object3"]
let xyzArr = ["xyz1", "xyz2","xyz3"]
let theArr = [[], [], [] ]

反正有对应关系吗?

推荐答案

我不确定您要问的是什么，但这将采用3个数组并将对象存储在window中:

I'm not sure what you're asking, but this would take the 3 arrays and store the objects in the window:

let objName = ["object1", "object2", "object3"];
let xyzArr = ["xyz1", "xyz2","xyz3"];
let theArr = [[], [], []];

objName.forEach((name, index) => {
  window[name] = {
    xyz: xyzArr[index],
    arr: theArr[index]
  };
});

console.log(object1);
console.log(object2);
console.log(object3);

我建议您使用名称空间而不是使其成为全局名称(有关

I would recommend using a namespace instead of making them global (more on that here), but I guess this works?
