That's fine, but the onclick handler doesn't do anything but disable
itself upon the first click. Perhaps this is a toy example and not the
real thing. Again, this link does not submit a form in the first place
unless a lot of information has been removed.
I've toyed with things like this (mostly by disabling form submit
buttons) but I've always been worried that something will interrupt the
submission process itself, leaving a user with a form that will never
submit again. :(
I'd love to hear some clever solutions to this problem. I started
writing a javascript function that would disable the submit button, then
schedule it to be re-enabled in, say, 30 seconds, but it was a bit fragile.
