Там же есть все в исходниках:
<script type="text/javascript">
$(document).ready(function () {

var createCookie = function (name, value, days) {
var expires;
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
expires = "; expires=" + date.toGMTString();
} else {
expires = "";
}
document.cookie = name + "=" + value + expires + "; path=/";
};
function getCookie(c_name) {
if (document.cookie.length > 0) {
c_start = document.cookie.indexOf(c_name + "=");
if (c_start != -1) {
c_start = c_start + c_name.length + 1;
c_end = document.cookie.indexOf(";", c_start);
if (c_end == -1) {
c_end = document.cookie.length;
}
return unescape(document.cookie.substring(c_start, c_end));
}
}
return "";
};
var cookie = getCookie(cookieName);
$("#cookieBanner").toggle(cookie == "", "slow");
$("#acceptCookies").click(function () {
//console.log("Creating cookie!");
createCookie(cookieName, 1, 30);
$("#cookieBanner").toggle("slow");
});
});
</script>
