Warum leert der folgende Code das Input-Feld namens "chat" nicht ???
<html>
<head>
<script language="Javascript">
function doSubmit()
{
if(document.chatform.chat.value == '')
{
alert('Please enter some text!');
document.chatform.chat.focus();
return false;
}
document.chatform.submit();
document.chatform.chat.value = '';
document.chatform.chat.focus();
return true;
}
</script>
</head>
<body style="background-color:#B8D3EF">
<form onSubmit="return doSubmit" action="chat.php" method="POST" target="chatwindow" name="chatform">
<input type="text" name="chat">
<input type="submit" value="send">
</form>
</body>
</html>
