Michael,
"var elem = $('frm');" will not throw error if element with id of
"frm" does not exist. It will assign null to "elem" variable.
Justin's example will work as expected and is one of the preferred
ways to check for element existence.
Alternatively, Element.observe('frm', 'submit', handler) will fail
*silently* if element is not present.
I would avoid using "try ... catch" as it happens to be quite
expensive (speed wise)
Hope this helps.
Best,
kangax
