其它要输出信息...</center>
</font>
6、记住来访时间

<HTML>
<HEAD>
<TITLE>Name - Visits - Last Visit</TITLE>

<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
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("您的尊姓大名：");
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);
var intLastVisit = (lastHereFormatting.getYear() * 10000)
　　(lastHereFormatting.getMonth() * 100) lastHereFormatting.getDate()
var lastHereInDateFormat = "" lastHereFormatting;
var dayOfWeek = lastHereInDateFormat.substring(0,3)
var dateMonth = lastHereInDateFormat.substring(4,11)
var timeOfDay = lastHereInDateFormat.substring(11,16)
var year = lastHereInDateFormat.substring(23,25)
var WWHText = dayOfWeek ", " dateMonth " at " timeOfDay
SetCookie ("WWhenH", rightNow.getTime(), exp)
return WWHText
}
function Count(info){
var WWHCount = GetCookie('WWHCount')
if (WWHCount == null) {
WWHCount = 0;
}
else{
WWHCount ;
}
SetCookie ('WWHCount', WWHCount, exp);
return WWHCount;
}
function set(){

SetCookie ('VisitorName', VisitorName, exp);
SetCookie ('WWHCount', 0, exp);
SetCookie ('WWhenH', 0, exp);
}
function getCookieVal (offset) {　
var endstr = document.cookie.indexOf (";", offset);　
if (endstr == -1)　　
endstr = document.cookie.length;　
return unescape(document.cookie.substring(offset, endstr));
}
function GetCookie (name) {　
var arg = name "=";　
var alen = arg.length;　
var clen = document.cookie.length;
