今天在网上找到的，，标题复杂 ，贴在这里，很好用的

第一步:把如下代码加入<head>区域中

<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("Who are you?");

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(){

VisitorName = prompt("Who are you?");

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;

var i = 0;

while (i <clen) {

var j = i + alen;

if (document.cookie.substring(i, j) == arg)

return getCookieVal (j);

i = document.cookie.indexOf(" ", i) + 1;

if (i == 0) break;

}

return null;

}

function SetCookie (name, value) {

var argv = SetCookie.arguments;

var argc = SetCookie.arguments.length;

var expires = (argc > 2) ? argv[2] : null;

var path = (argc > 3) ? argv[3] : null;

var domain = (argc > 4) ? argv[4] : null;

var secure = (argc > 5) ? argv[5] : false;

document.cookie = name + "=" + escape (value) +

((expires == null) ? "" : ("; expires=" + expires.toGMTString())) +

((path == null) ? "" : ("; path=" + path)) +

((domain == null) ? "" : ("; domain=" + domain)) +

((secure == true) ? "; secure" : "");

}

function DeleteCookie (name) {

var exp = new Date();

exp.setTime (exp.getTime() - 1);

var cval = GetCookie (name);

document.cookie = name + "=" + cval + "; expires=" + exp.toGMTString();

}

// End -->

第二步:把如下代码加入<body>区域中

<script LANGUAGE="Javascript">

document.write("Hello " + Who() + ". <br>您已经登录本站" + Count() + " 次了.<br>上次登录是:" + When() +".");

</script>
