Using document.getElementById() - as you suggest - will get you the
one and only element in the document having that ID. You can then
see if that element has the class name you want, like this, perhaps:

function hasClass(element, myClass) {
  var myClass = myClass.replace(/\-/g, "\\-");   // escape hyphens
  var re = new RegExp("\\b ?"+myClass+"\\b");
  if (!element.className) return false;
  return re.test(element.className);
}


Cordially,
David
