请教一个小问题
<html>
<head>
<script>
var w;
function debug(msg)
{
if (w==null)
{
var w=window.open( " ", "win1 ", "width=600,height=300,resizable ");
var t=w.document.open( "text/plain ");
}
t.writeln(msg);
}
</script>
<title> Untitled Document </title>
<meta http-equiv= "Content-Type " content= "text/html; charset=gb2312 ">
</head>
<body bgcolor= "#FFFFFF " text= "#000000 ">
<input type= "button " name= "button1 " value= "push me " onclick= "debug( 'you have push me '); ">
</body>
</html>
但是无论我点几次button，文本文件上只显示一次 'you have push me '。但是我并没有t.close()，所以我点一次按钮应该可以每次都写到t所代表的文本文件上啊。错在哪里，请高手指点
