Bad design begets stubborn problems - sorry :) Checkboxes by design
are to be checked and unchecked. You are trying to code in behavior
that a checkbox doesn't have. Expect the unexpected.

In any event (no pun intended) what you want to do is DISABLE the
checkbox once it has been checked.

(ultra terse code example follows)
function d(cb)
  cb.disabled = true;

<input type="checkbox" name="foo" onclick="d(this)" />

Quickly tested in IE and FireFox. Should do what you want..


The user doesn't have JS disabled. If they DO - they can check boxes
to the moon, no matter how you script it. So if all I want to do is
get around your little checkbox issue, I can easily do that. I would
come up with a better design. My .02.

Then by design you have BAD design. Each checkbox should have a
unique name. Again, just my 02.
