javascript - 从数组动态创建对象

Question

我想生成一个动态对象并为其赋值。下面是代码

var chunk = "INTERNATIONALISATION#LANGUAGE#DICTIONARY#EN";
var c = chunk.split('#');
var a = {};

所以输出应该是这样的

a["INTERNATIONALISATION"]["LANGUAGE"]["DICTIONARY"]["EN"] = 10;

尝试循环数组，但目前没有任何效果。请告知。

Answer 1

试试这个:

var chunk = "INTERNATIONALISATION#LANGUAGE#DICTIONARY#EN";
var c = chunk.split('#');
var a = {};
var lastKey = c.pop();
c.reduce((obj, key) => obj[key] = obj[key] || {}, a)[lastKey] = 10;

为了更方便，你可以将它放在一个函数中:

const dynamicAssign = (object, stringPath, value) => {
    const path = stringPath.split('#');
    const lastKey = path.pop();
    const target = path.reduce((obj, key) => obj[key] = obj[key] || {}, object);
    target[lastKey] = value;
};

const a = {};
dynamicAssign(a, "INTERNATIONALISATION#LANGUAGE#DICTIONARY#EN", 10);
