URLSearchParams.toString()

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

 

The toString() method of the URLSearchParams interface returns a query string suitable for use in a URL.

Note: Returns the query string without the question mark. This is different from window.location.search which includes it.

Syntax

URLSearchParams.toString()

Returns

A string without the question mark.

Example

let url = new URL('https://example.com?foo=1&bar=2');
let params = new URLSearchParams(url.search.slice(1));

//Add a second foo parameter.
params.append('foo', 4);
console.log(params.toString());
//Prints 'foo=1&bar=2&foo=4'

// note: params can also be directly created
let url = new URL('https://example.com?foo=1&bar=2');
let params = url.searchParams;

// or even simpler
let params = new URLSearchParams('foo=1&bar=2');
