Removing all classNames of div

How can I remove all classnames of div using prototype without knowing
the classNames? for example:

removeClassName(''red'') will remove ''red''
from class="red borderblack
other" <- but what if I did not know what the classnames were and
wanted to remove all of them so that class would become class="" ?

Thanks

There is no way that I can see, with Prototype, to do such a thing,
although there is a classNames() method which returns an element''s
class names as an Element.ClassNames object.

You could also try

$(''foo'').writeAttribute(''class'','''');

Re: Removing all classNames of div

Am I missing something here, or would it be easier to write

${''DIV_ID_NAME''}.className="";

?

Cheers,

Dave

Re: Removing all classNames of div

you''d have to do one pass to find all the classNames using  $
(''DIV_ID_NAME'').classNames().inspect(); and then once you had
them in
an array you''d be able to do another pass based on that new array and
remove them with
$(''DIV_ID_NAME'').removeClassName(''CLASS_NAME'');
one
at a time.
