本文实例讲述了JS基于cookie实现来宾统计记录访客信息的方法。分享给大家供大家参考。具体如下：

这里使用JavaScript记录访客的来宾信息，记录是第几次来访，显示的信息有：您的名字;您浏览该网页的次数;您上次浏览网页的时间。可以更改姓名。

运行效果如下图所示：

具体代码如下：

<html>
<head>
<title>记录客户信息</title>
<script language="JavaScript">
<!--
var expDays = 30;
var exp = new Date(); 
exp.setTime(exp.getTime() + (expDays*24*60*60*1000));
function Who(info){
var VisitorName = GetCookie('VisitorName')
if (VisitorName == null) {
VisitorName = prompt("请输入姓名：",'');
SetCookie ('VisitorName', VisitorName, exp);
}
return VisitorName;
} 
function When(info){
var rightNow = new Date()
var WWHTime = 0;
WWHTime = GetCookie('WWhenH')
WWHTime = WWHTime * 1
var lastHereFormatting = new Date(WWHTime); // 访问时间记录r
var intLastVisit = (lastHereFormatting.getYear() * 10000)+(lastHereFormatting.getMonth() * 100) + lastHereFormatting.getDate()
var lastHereInDateFormat = "" + lastHereFormatting; 
var dayOfWeek = lastHereInDateFormat.substring(0,3)
