I am working with it for an hour but I can't figure out what is wrong in that.
<html>
<body>
<input type="button" value="set" onclick=setcook()>
<input type="button" value="get" onclick=getcook()>
<script>
function setcook() {
document.cookie = "un=nu";
}
function getcook() {
if (document.cookie.length != 0)
alert(document.cookie);
else {
alert("cookie not available");
}
}
</script>
</body>
</html>
