javascript - 从 URLSearchParams 转换字符串数组值

Question

如何将字符串数组值转换为 Javascript 数组对象？

var querystring = 'lang[]=EN&lang[]=FR&type[]=1&type[]=2';

进入:

{
    lang: ['EN', 'FR'],
    type: ['2']
}

低于我的尝试:

let params = new URLSearchParams(decodeURI(querystring));
let entries = params.entries();

let result = {}
for(let entry of entries) { // each 'entry' is a [key, value]
    result[entry[0]] = entry[1];
}
return result;

结果是:

[{
    "name": "lang[]",
    "value": "EN"
}, {
    "name": "lang[]",
    "value": "FR"
}, {
    "name": "type[]",
    "value": "2"
}]

最简单的版本是使用像 qs 这样的库

https://www.npmjs.com/package/qs#parsing-arrays

var withArray = qs.parse('a[]=b&a[]=c');

结果

a: ['b', 'c']
