Just some comments..
How about the following?
When the form is submitted, display a page without a submit button that
1) indicates the form is being processed and 2) submits the form data
for actual processing.
And in the meantime, where is the page with the form with the data that
has to be submitted ?
...
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.
Ok, how about having the submit button inside of a <div>, of which you
toggle the display:visible style attribute ?
Once it is clicked, it disappears.
After all, once you have clicked it once, you really /don't/ need it
ever again, not for the same form you don't.
You may need the same form again, with other values, but that would be
after the server has accepted the first post, and sent maybe a new clean
form.
