.id vs .className on returning boolean values in Javascript

Question

I am trying to get a webelement's id and class if it has one. The first check using the id works fine, but the one checking the class doesn't. I don't know why but ' id ' returns true but ' class ' does not return anything. Any ideas on why this doesn't work and how to make it work?

 var id = currentElement.id;
      if(id)
      {
        targetDocument.write(" id=\""+currentElement.id+"\"");
      }
   var class = currentElement.className;
      if(class)
      {
        targetDocument.write(" class=\""+currentElement.className+"\"");
      }

`class` is a reserved word... http://stackoverflow.com/questions/7524618/why-is-class-a-reserved-word-in-javascript — , Aug 08 '13 at 19:20
Open your browser's developer console. This should be the first thing you do when troubleshooting code. — , Aug 08 '13 at 19:24

In JavaScript, class is a reserved word. try className (for example) instead.
