[Javascript] How to refer to an HTML element's ID attribute

Perhaps you should write a routine like "getObject(nameOrID)" which tests
for the existence of the object via getElementById, and if this is
undefined, try getting it by name.  If either is defined and exists, return
the object handle to it, or return null (-1) if it isn't.

At least that is one way of encapsulating a solution that will work on a lot
of different platforms/versions.  Any additional "tweaks" that are necessary
to handle oddball browsers can then be put in one place -- getObject -- 
without requiring massive rewrites of all your subsidiary code.
