JavaScript "element.className" returns the value of all classes defined
on "element", but for getting all elements having a certain class then,
no, there is no built-in JavaScript function. Plenty of solutions exist
if you need one - google "javascript getelements by class name"
for a few.

In your example problem, though, you don't need this. An ID is, by
definition, unique in a document, so using getElementById() then
checking its className value(s) should work just fine.

Cordially,
David
