That¹s about the worst thing you could do ­ the form simply won¹t work for
people who turn off, or don¹t have access to, JavaScript. That¹s more people
(and devices) than you think ­ heck even some corporate firewalls strip out
JS from pages as the packets pass through! It¹s also an invalid href
attribute (the javascript: pseudo-protocol) that, at the very least, should
be replaced with the appropriate event handler (in this case, onClick). For
example:

<a href=²fallbackURL.html² onclick=²validateForm();²> ... </a>

The golden rule is never, ever completely rely on JavaScript for anything,
and always plan for it not being available.
