Explain why it's not the same as your question. Both questions are asking for how to update a query string. — Adrian

The question referenced above was asked and answered in 2011. The answer does not reflect standard contemporary best practice, using URLSearchParams API. I have posted an answer appropriate to 2018 below. — Rounin

URLSearchParams is now the standard API for manipulating a URL query string.

Working Example:

N.B. In the example below a string variable (var windowLocationSearch) is used as a stand-in for window.location.search which actually represents the query string at the end of the URL.

// Set window.location.search
var windowLocationSearch = 'page=2&order=title';

// Log window.location.search
console.log(windowLocationSearch);

// New URLSearchParams object
var searchParams = new URLSearchParams(windowLocationSearch);

// delete 'page' key from searchParams
searchParams.delete('page');

// Return query string from searchParams
windowLocationSearch = searchParams.toString();

// Log updated window.location.search
console.log(windowLocationSearch);
