Visibility or active/clickable by object status value

[admin]

You have a syntax error, it should be:

Code:

$(function() {
  $('.hidden-by-value').each(function(_, el) {
    var addr = $(el).data('object');
    if (addr) {
      grp.listen(addr, function(obj) {
        var value = obj.value;
        $(el).css('visibility', value ? 'visible' : 'hidden');
      });
    }
  });
});
