Last Updated : 14 Oct, 2021

In URLSearchParams interface, the has() method returns a Boolean which tells us that if the parameter with input name exists it will return true, else false. Syntax:

var Bool = URLSearchParams.has(name)

Returns: True - if name present, else it will return False. Parameters: name - Input the name of the parameter. Example1:

javascript

let url = new URL('https://example.com?par=5&bar=4');
let param = new URLSearchParams(url.search.slice(1));

param.has('bar') === true;

Output:

true

Example2: When input parameter is not present

javascript

let url = new URL('https://example.com?par=5&bar=4');
let param = new URLSearchParams(url.search.slice(1));

param.has('foo') === true;
