Ciao a tutti, ho provato ha realizzare un guestbook in jsp, e ho un problema lato client nella validazione, così mi rivolgo ai vari guri di questo forum. Non riesco ad accedere alla textarea in fase di validazione mentre riesco con i campi input text, non riesco a capire dove sbaglio: ecco il codice della mia paginetta HTML, grazie in anticipo a qualche anima buona:
<html>
<head>
<title>Guestbook</title>
<script language="JavaScript">
<!--
function valida()
{
var a = document.gbform.nick.value;
var b = document.gbform.testo.value;
if(a == "" | b == "")
{ win = window.open("Nuovapagina.html", "np", width="200", height="200");
return false;
win.focus();
}return true;
}
//-->
</script>
</head>
<body>
<form name="gbform" action="Guestbook6.jsp" method="post" onSubmit="return valida()">
<table style="z-index: 102; left: 25px; position: absolute; top: 116px">
