Javascript Cookies

[fr1974]

Aquí os dejo el ejemplo que no me funciona :

<script>
function setCookie(name, value, expires) {
document.cookie = name + "=" + escape(value) + "; path=/" + ((expires == null) ? "" : "; expires=" + expires.toGMTString());
}


function getCookie (name) {
var dc = document.cookie;
var cname = name + "=";

if (dc.length > 0) {
begin = dc.indexOf(cname);
if (begin != -1) {
begin += cname.length;
end = dc.indexOf("", begin);
if (end == -1) end = dc.length;
return unescape(dc.substring(begin, end));
}
}
return null;
}



function delCookie(name) {
document.cookie = name + "=; expires=Thu, 01-Jan-70 00:00:01 GMT" + "; path=/";
}

</script>




<script>
var exp = new Date(); //create new date object
exp.setTime(exp.getTime() + (1000 * 60 * 60 * 24 * 30)); //set it 30 days ahead
setCookie("pol","123456", exp);
</script>


<script>
var count=getcookie('pol');
if (count!="123456")
{
alert ('ok');
}
</script>
