Change font text from Visu

[JoseJimenez94]

You can add/remove classes like this:

Code:

$('.cls1').addClass('cls2');
$('.cls3').removeClass('cls4');

Thanks admin,
but i'm not sure how to use those functions in javascript.
I mean, if I have a button (address 1/1/1) that when pressed, I change the additional class of a text (from .cls1 to .cls2 for example), should i put in javascript ?:

      grp.listen('1/1/1', function(obj) {
      $('.cls1').addClass('cls2');
      }

, and in the additinal class of the text what should i write: cls1, cls2 or what?

Sorry for the inconvenience
