Went looking to find out...

So innerHTML is a MS proprietary extension that isn't part of the DOM
standard that happens to be supported by Firefox.  Presumably because
it is used by so many sites.  Thus testing on FF and IE didn't show it
as being a problem.

So a DOM-way of doing the same would be:

ajax_elid('result').childNodes[0].nodeValue = '= ' + result;
ajax_elid('symbol').childNodes[0].nodeValue = '*';

However, this fails if the node is empty.  ('Has no properties').  A
helper/wrapper to check for that and add a childNode would be useful.

I appreciate your comment, Ron.  Thanks.

I'll refrain from working out a complete wrapper here, but will put
one into the distribution.
