I''ve seen a few frameworks use the following:

function $(id) { return document.getElementById(id); }

Then to use:

$(''something'').innerHTML = ''blah'';

I''m just trying to roll this out to my site and so far doing this has
saved about 8KB of javascript (lots of ajax/dynamic elements). I just
want to know whether there''s any browser problems with doing this?
I''ve tested it on IE7, FF2, Safari 3 and IE6 and can''t see any
problems. Are there any browsers that this won''t work on?

Thanks
