Get current url and modify it in view, without laravel 5.3 controller?

Question

JavaScript

You need to change the number of results on the search page.
The search worked, and the URL may be different:

->http://lara53/products/search/5?searcher=Product+Andrew
->http://lara53/products/search/5?searcher=Andrew

etc.
Number 5, the number of results, at the bottom I have a select that sends to different URLs.
How can I now change only .../5?...the number using Laravel 5.3 or jQuery , while preserving the search results ?

Take the current URL, for example via window.location.href, do a replace for the link and then redirect the user.
