addClass () to an object via an external link

Navigation

I need to create a click () function for 8 links that are in pagina X , each link will take me to a specific slide in a pagina Y .

The slide is active when it is with Class selected , so my idea is as follows:

The user clicks on link 1 on page X is taken to page Y with slide 1 active.

The user clicks on link 2 on page X is taken to page Y with slide 2 active.

And so it goes ...

So summarizing, how do I make this addCLass () work after loading the Y page.

If it has not been very clear I edit.

Thank you.

The idea that occurs to me is to pass on the query string link in order to analyze on the arrival page which slide the class should receive. For example: 

<a href="/link?slide=1">Slide 1</a>
<a href="/link?slide=2">Slide 2</a>

and slide page: 

var slide = location.search.match(/slide=(\d+)/)[1];
var slides = document.querySelectorAll('.slides');
slides[slide].classList.add('selected');

That's the skeleton. If you need help implementing implement, I can add more details as soon as I leave work.
