This repository might be useful for you: https://github.com/proengsoft/laravel-jsvalidation/wiki/Validating-Examples
Also in general any javascript framework or library can handle this for you.
You have two options to handle this. One is using an API when you want to go to the next tab. If something is wrong you show some error message and so on. The other options is to do the validation on the javascript side and handle everything with javascript. That is totally up to you!
