monolithed, вы правы)
Vuzy, лучше так:
<form method="POST" action="" id="form_who_should_be_checked">
<input name="anything" value="text">
<input type="submit">
</form>
<script>
document.getElementById("form_who_should_be_checked").onsubmit=
function() {
alert(this.anything.value);
return false;
}
</script>
