本教程举了两个实例说明利用cookie实现访问次数统计的代码,包括有php,js 两种方法
-
<?php
-
global $count;
-
$count=1;
-
if(!isset($_COOKIE["visittime"])){ setcookie("visittime",date("y-m-d H:i:s"));
-
setcookie("visitcount",1); echo "欢迎你第一次访问网站!";
-
}
-
else{
-
setcookie("visittime",date("y-m-d,H:i:s"),time()+60); $count=$_COOKIE['visitcount']+1;
-
setcookie("visitcount",$count); echo "你上次访问网站的时间为:".$_COOKIE['visittime'];
-
echo "<br>";
-
}
-
echo "你第".$_COOKIE['visitcount']."访问网站的时间为:".date("y-m-d H:i:s");
-
?>
下面看个简单的js实现访问次数统计代码,脚本说明:第一步:把如下代码加入<body>区域中:
-
<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)
-
message=" Welcome to my page!";
-
if(visit== 2)
-
message=" I see you came back !";
-
if(visit == 3)
-
message=" Oh, it's you again!";
-
if(visit == 4)
-
message=" You must be curious!";
-
if(visit == 5)
-
message=" You're practically a regular!";
-
if(visit == 6)
-
message=" You need a hobby!";
-
if(visit == 7)
-
message=" Nothing better to do?";
-
if(visit == 8)
-
message=" Don't you ever sleep?";
-
if(visit == 9)
-
message=" Get a life!!!";
-
if(visit >= 10)
-
message=" Rent is due on the 1st of the month!";
-
alert("n"+"你的浏览器已经访问过本页" + visit +"次了"+"n"+"n"+message);
-
}
-
function ResetCounts() {
-
var expdate = new Date();
-
expdate.setTime(expdate.getTime() + (24 * 60 * 60 * 1000 * 365));
-
visit = 0;
-
SetCookie("visit", visit, expdate , "/", null, false);
-
history.go(0);
-
}
-
-
</Script>
-
<FORM>
-
<CENTER>
-
<INPUT NAME="update" TYPE="BUTTON" VALUE="查看次数" OnClick="history.go(0)">
-
<INPUT NAME="reset" TYPE="BUTTON" VALUE="重新计数" OnClick="ResetCounts()">
-
</CENTER>
-
</FORM>
