You will need just this tiny js script:
function disableOnSubmit(form ){
for (var i = 0; i < form.length; i++){
var e = form.elements[i];
if (e.type.toLowerCase() == "button" || e.type.toLowerCase()
== "reset" || e.type.toLowerCase() == "submit") {
e.disabled=true;
}
}
}
and then add :
<form method="POST" action="/account" name="fm" onsubmit="disableOnSubmit(
document.fm)" >
That's all what you need - i think
