This is complete garbage the javascript: psuedo protocol should not be
used,
the comp.lang.javascript FAQ is very clear on this (and the group isn't
even suggesting it from just an accessibility perspective, a simply code
reliability perspective is enough, quite apart from the considerable
accessibility issues with it.  http://jibbering.com/faq/#FAQ4_24

Well you can't rely on onChange either, and onclick only realisitically
excludes NN4, and as you need a submit button in any case, it's not
disadvantaged much.  onClick is certainly reasonably safe, and duplicates
the "instant response" which people presumably want by using onchange.
Of course you need a fallback submit button, but then you do anyway for
the non javascript people.
