cookies in javascript?

I'd suggest just playing around with them. That's what I did to learn them. I made this program (about as simple as you can get with cookies) using some cookie functions I found on the net.

Code:
<script language=javascript>
function getCookie(name) {
var start = document.cookie.indexOf(name+"=");
var len = start+name.length+1;
if ((!start) && (name != document.cookie.substring(0,name.length))) return null;
if (start == -1) return null;
var end = document.cookie.indexOf(";",len);
if (end == -1) end = document.cookie.length;
return unescape(document.cookie.substring(len,end));
}
function setCookie(name,value,expires,path,domain,secure) {
document.cookie = name + "=" +escape(value) +
((expires) ? ";expires=" + expires.toGMTString() : "") +
((path) ? ";path=" + path : "") +
((domain) ? ";domain=" + domain : "") +
((secure) ? ";secure" : "");
}
</script>
<body>
<form name=blahForm>
<script language=javascript>
var blah = getCookie("cookieTest");
var expireDate = new Date();
if (blah != null) {
document.write("Welcome back " + blah + "<br><br>");
expireDate.setTime(expireDate.getTime() - 1);
document.write("<input type=button value='Destroy Cookie' onclick='setCookie(\"cookieTest\", \"\", expireDate);alert(\"cookie erased\");'><br><br>");
}
else {
document.write("<input type=text name=blahText><br><br>");
expireDate.setTime(Date.parse("01/06/2070"));
document.write("<input type=button value='Remember Me' onclick='setCookie(\"cookieTest\", blahForm.blahText.value, expireDate);alert(\"cookie saved\");'><br><br>");
}
</script>
<input type=button value='Refresh Page' onclick='window.location.reload()'>
</form>
