每次用户删除时设置 cookie

Question

我想在用户每次删除它时创建一个 cookie，使用 Javascript。

比如我有很多cookies，甚至有一些cookies对滥用网站的用户设置了封禁时间。

基本上我想设置一个 cookie，每当删除所有 cookie 时都会设置该 cookie。

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

以下是每次用户删除 cookie 时我如何创建它：

<?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>
