$("#warningmsg").each(highlightWarningMsg);
That would still be a bad way to do it i'd say, because if theres more than
one element with the id 'warningmsg' (I know there shouldnt be, but you cant
count on these things), it would fire more than once. I would just use if
($('#warningmsg')[0]).

You could also say this:
$("#warningmsg").each(highlightWarningMsg);
Each won't call the fn at all unless the element exists. If that's the
only
place the fn is called, just drop an anonymous function there. Or you
could
turn it into a plugin and do this:
$("#warningmsg").highlightMsg();
