Recently I've done this by having a standard <a href...> link which goes
to a "delete.cfm" confirmation page, but if the user has JS enabled then
clicking on the link asks them to confirm, then directs them straight to
a "destroy.cfm" page which only accepts calls via a POST.
E.g. (new lines added for ease of reading):
<a href="/object/delete/123"
onclick="if confirm('Are you sure?') {
var f = document.createElement('form');
this.parentNode.appendChild(f);
f.method = 'POST';
f.action = "/object/delete/123";
f.submit();
}"
>link</a>

Hi Paul,
A better/easier way to do it would be to not use javascript and instead
submit to a confirmation page i.e. "Are you sure you want to delete...".
Problem with javascript is if the user's system has it switched off,
then they can delete by accident and get angry.
This is true of all form validation. If you need to adhere to WAI
(especially if you're working in government which I seem to remember you
do) then you shouldn't rely on javascript to report
validation/confirmation, it breaks Priority 1 checkpoint 6.3:
"And if you use applets and scripts (Priority 1)
* 6.3
<http://www.w3.org/TR/WAI-WEBCONTENT/wai-pageauth.html#tech-scripts>
Ensure
that pages are usable when scripts, applets, or other programmatic
objects are turned off or not supported. If this is not possible,
provide equivalent information on an alternative accessible page.
"
