方法一：通過Cookie互動。一共是三個檔案，分別為：
index.htm,action.php,main.htm
原理為前台頁面main.htm和後台action.php通過頁面架構
index.htm組織起來，將action.php的頁面寬度設為0，這樣並不
影響顯示。action.php將資訊放入cookie中，main.htm通過讀取
cookie來實現互動。在main.htm中也可以通過重新讀取action.php
來實現控制後台CGI程式。
index.htm

<html>
<head>
<title>Test</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
</head>
<frameset framespacing="0" border="false" frameborder="0" cols="0,*">
<frame name="leftFrame" scrolling="no" noresize src="action.php">
<frame name="rightFrame" scrolling="auto" src="main.htm">

<p>本頁使用頁面架構，但是您的瀏覽器不支援。</p>
</body>
</noframes>
</html>
---------------------------------------------------------------
action.php
---------------------------------------------------------------
<?
srand((double)microtime()*1000000);
$result=rand(0,100);
setcookie("action",$result,time()+900,"/");
?>
---------------------------------------------------------------
main.htm
---------------------------------------------------------------
<html>
<head>
<title>Test</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<script language="javascript">
function get_cookie()
{
document.test.current_cookie.value=document.cookie;
}
</script>
</head>
<body bgcolor="#FFFFFF">
<form name="test" >
當前參數為<input type="text" name="current_cookie" size="80" maxlength="1000">
</form>
<script language="javascript">
setInterval("get_cookie()",200);
</script>
<br>
<a href="action.php" target="leftFrame">重新讀取Cookie</a>
</body>
</html>
---------------------------------------------------------------
方法二：直接通過parent.*.*來實現互動。一共是三個檔案，分別為：
index.htm,action.php,main.htm，其中index.htm和前面的一樣。
原理為通過parent.rightFrame.test.current_cookie.value直接傳遞
資訊。
action.php
---------------------------------------------------------------
<?
srand((double)microtime()*1000000);
$result=rand(0,100);
?>
<script language="javascript">
parent.rightFrame.test.current_cookie.value="<? echo $result?>";
</script>
---------------------------------------------------------------
main.htm
---------------------------------------------------------------
<html>
<head>
<title>Test</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
</head>
<body bgcolor="#FFFFFF">
<form name="test" >
當前參數為<input type="text" name="current_cookie" size="80" maxlength="1000">
</form>
<br>
<a href="action.php" target="leftFrame">重新讀取Cookie</a>
</body>
</html>
