UC知道JavaScript innerHTML问题

代码：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>无标题文档</title>
</head>
<Script language="javascript" type="text/javascript">
function a(txt){
txt.innerHTML=txt;
}
a('你好');//这里怎么写才能调用啊？
setTimeout("a('你好')",1);
</Script>
<body>
<div id="txt"></div>
</body>
</html>
问题：我自定义了一个a函数在调用中a('你好');div不显示，而用定时器调用setTimeo

改为:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>无标题文档</title>
</head>
<body>
<div id="txt"></div>
</body>
<Script language="javascript" type="text/javascript">
function a(txt){
document.getElementById('txt').innerHTML = txt;}
a('你好');//这里怎么写才能调用啊？
//setTimeout("a('你好')",1);
</Script>
</html>
你这样调用必须写在div定义的
