本教程舉了兩個實例說明利用cookie實現訪問次數統計的代碼，包括有php教程 js 兩種方法
<?php
global $count;
$count=1;
if(!isset($_COOKIE["visittime"])){ setcookie("visittime",date("y-m-d H:i:s"));
setcookie("visitcount",1); echo "歡迎你第一次訪問網站!";
}
else{
setcookie("visittime",date("y-m-d,H:i:s"),time()+60); $count=$_COOKIE['visitcount']+1;
setcookie("visitcount",$count); echo "你上次訪問網站的時間為:".$_COOKIE['visittime'];
echo "<br>";
}
echo "你第".$_COOKIE['visitcount']."訪問網站的時間為:".date("y-m-d H:i:s");
?>
下面看個簡單的js實現訪問次數統計代碼
腳本說明:
第一步:把如下代碼加入<body>區域中
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
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 = (2 < argc) ? argv[2] : null;
var path = (3 < argc) ? argv[3] : null;
var domain = (4 < argc) ? argv[4] : null;
var secure = (5 < argc) ? 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 DisplayInfo() {
var expdate = new Date();
var visit;
expdate.setTime(expdate.getTime() + (24 * 60 * 60 * 1000 * 365));
if(!(visit = GetCookie("visit")))
visit = 0;
visit++;
SetCookie("visit", visit, expdate, "/", null, false);
var message;
if(visit == 1)

}
function ResetCounts() {
var expdate = new Date();

}
// End -->
