Convert multilevel object to query string

Question

How i can convert object into location%5Bokrug%5D%5B%5D=38&location%5Bokrug%5D%5B%5D=41:

let filter = {
    location: {
        okrug: [38, 41]
    }
}

URLSearchParams does not help:

console.log(new URLSearchParams(filter).toString()) //got location=%5Bobject+Object%5D

location%5Bokrug%5D%5B%5D=38&location%5Bokrug%5D%5B%5D=41

try `encodeURIComponent(JSON.stringify(filter))`, first converts the JSON into a string with no whitespace, then encodes it. — zmehall, Oct 28 '22 at 18:48
how is this working with a comma instead of a period: `new URLSearchParams(filter),toString()`? — rainbow.gekota, Oct 29 '22 at 22:12

You could use a query parser library like qs that has been thoroughly tested.

I included a snippet that uses version 6.11.0 below.

const filter = { location: { okrug: [38, 41] } };
  
console.log(Qs.stringify(filter, { encode: true }));

<script src="https://cdnjs.cloudflare.com/ajax/libs/qs/6.11.0/qs.min.js"></script>

location%5Bokrug%5D%5B0%5D=38&location%5Bokrug%5D%5B1%5D=41
