Ik heb hier een script voor het filteren van een resultaat dat bestaat uit checkboxes, dropdowns, radiobuttons.
wat ik nu heb is dat bij het klikken op de submit button de zoekresultaten worden meegegeven in de link.
wat ik wil dat ik bij het keuze maken van bijv. dropdown het gelijk in de link wordt meegeven voordat ik op de submit button klik.
Hoe kan ik dat oplossen?

dit is mijn script:
