javascript to check css element

[admin]

If you want to do a kind of AND/OR gate then you need this. Change group addresses as needed and you can change && (AND) to || (OR).

Code:

$(function(){
   var v1 = false, v2 = false;

   function set() {
      $(".hidebyknx").toggleClass("hide", v1 && v2);
   }

   grp.listen('1/1/1', function(object, state) {
      v1 = object.value;
      set();
   }, true);

   grp.listen('1/1/2', function(object, state) {
      v2 = object.value;
      set();
   }, true);
});
