It's quite simple in JavaScript.

First, remove the action from the form definition
<form method="post" name="login" id="login" >

Then, instead of using type=submit, use type=button.
<input type=button name=submit value="Login"
Onclick="SubmitForm(this.form);">

function SubmitForm(form)
{
if (form.domain.value == "xxx")
form.action = "xxx"
else
form.action = "zzz";

form.submit(); // Submit the page
return true;
}
