changing an element's class via AJAX

Greetings folks,

Does anyone know how I can modify a DOM element’s
class on the fly via AJAX? Is this even possible?

I basically want to toggle a background color after the
user updates a pass/fail attribute on one of my models.

Thanks in advance.

Regards,
Franz

Use prototype addClassName, removeClassName, toggleClassName utilities
or just fiddle with the element's className directly
