It would be these fixed frontend bars, the problem is that I can not find how a class is inserted to by things in it.

Example:

<div class="main-menu">conteudo</div>

After rolling the screen a bit, the class is inserted:

<div class="main-menu isStuck">conteudo</div>

I need to be observing when and when to remove this class for some "clones" within it.

jquery

Use .on with scroll to observe, when scrolling the screen, whether or not the element has class :

$(window).on('scroll', function(){
   if($('.main-menu').hasClass('isStuck')){
     console.log("tem a classe");
   }else{
     console.log("não tem a classe");
   }
});
