设置每次用户删除cookie

Question

我想创建一个cookie每次用户删除它，使用Javascript。

例如，我有很多cookie，甚至有些cookie对滥用网站的用户设置了禁用时间。

基本上我想设置一个cookie，它将在所有cookie被删除时设置。

顺便说一句，我不想创建相同的cookie回来。但是，我只想创建一个指示cookie。

我是如何在每次用户删除它时创建一个cookie的:

<?php
if ($_COOKIE["CookieIsThere"] == "no") {
echo "Why did you delete the cookies? Come on, we wanted to help you!";
setcookie("CookieIsThere", "yes");
} else {
setcookie("CookieIsThere", "yes");
}
echo "<br>". $_COOKIE["CookieIsThere"];
?>

<script>
function getCookie(name) {
var dc = document.cookie;
var prefix = name + "=";
var begin = dc.indexOf("; " + prefix);
if (begin == -1) {
begin = dc.indexOf(prefix);
if (begin != 0) return null;
}
else
{
begin += 2;
var end = document.cookie.indexOf(";", begin);
if (end == -1) {
end = dc.length;
}
}
// because unescape has been deprecated, replaced with decodeURI
//return unescape(dc.substring(begin + prefix.length, end));
return decodeURI(dc.substring(begin + prefix.length, end));
} 
function doSomething() {
var myCookie = getCookie("CookieIsThere");
if (myCookie == null) {
// do cookie doesn't exist stuff;
document.cookie = "CookieIsThere=no";
location.reload();
console.log(myCookie);
} else {
// do cookie exists stuff
console.log(myCookie);
}
}
setInterval(function () {
doSomething();
}, 1000);
</script>
