<form name="form1" method="post" action="">
<textarea name="textarea" cols="25" rows="11"></textarea>
</form>
用什么办法可以让这个文本域的内容总完整显示最下面的内容而把上面的内容缩上去呢?

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>滚动TextArea中内容到底部</title>
</head>
<body>
<textarea id="txb" rows="10">

<script language="javascript">
function Scroll()
{
var txb = document.getElementById('txb');
var psnObject = txb.Span;
if ( !psnObject )
{
psnObject = document.createElement('SPAN');
txb.Span = psnObject;
}
txb.appendChild(psnObject);
