That doesn't work, still can submit twice. Even this code doesn't work:
submitted = 0;
function submit_once() {
if (++submitted > 1) {
alert("Your request is being processed.\nPlease be patient.");
try {
event.returnValue = 0; // work-around for IE
} catch (e) {}
return 0;
}
return 1;
}
Seems to be some race condition in javascript/firefox?
