JavaScript Cookie顯示用戶上次訪問的時間和次數(shù)

更新時間：2009年12月08日 01:15:16 作者：

用cookies記錄用戶的訪問時間與次數(shù)，然后再次訪問時，在讀取。

httml代碼：

 
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> 
<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"> 
<title>Untitled Document</title> 
</head> 
<body onload="start()"> 
</body> 
</html> 

JS代碼：

復(fù)制代碼代碼如下:

 
<script language="JavaScript" type="text/javascript">
