Javascript Cookie Code Needed

[crewdy]

Hi all,

I am using a piece of Javascript code to toggle the viewing of divisions of my website, so a division can be "opened" and "closed" at user disgresion. You can see a live example of what I mean here: www.crewdy.co.uk/layout.html

The problem that I have is that when the page is refreshed or a link is clicked, the page reloads and the divisions are re-opened. I am looking for a piece of code which will enable a cookie, telling the browser to keep that division open until the user next clicks the "open/close" link.

If anybody knows of where I can find a piece of code, or if anybody could help to write a piece of code to go with this, I would be greatly appreciative. May be safe to note that my JavaScript knowledge is zero-to-none; the code I am currently using is below.

Thanks,
Pete

<!--
function toggleLayer(whichLayer)
{
 if (document.getElementById)
 {
  var style2 = document.getElementById(whichLayer).style;
  style2.display = style2.display? "":"none";
 }
}

Here's something I've used to save a user's background color preference:

<script language="JavaScript">

var expDays = 90;
var exp = new Date();
exp.setTime(exp.getTime() + (expDays*24*60*60*1000));
function color(){
var favColor = GetCookie('color');
if (favColor == null) {
favColor = prompt("What is your favorite background color?");
SetCookie('color', favColor, exp);
}
document.bgColor=favColor;
return favColor;
}
function set(){
favColor = prompt("What is your favorite background color?");
SetCookie ('color', favColor, exp);
document.location="fgd.htm"
}
function getCookieVal (offset) {
var endstr = document.cookie.indexOf (";", offset);
if (endstr == -1)
endstr = document.cookie.length;
return unescape(document.cookie.substring(offset, endstr));
}
function GetCookie (name) {
var arg = name + "=";
var alen = arg.length;
var clen = document.cookie.length;
var i = 0;
while (i < clen) {
var j = i + alen;
if (document.cookie.substring(i, j) == arg)
return getCookieVal (j);
i = document.cookie.indexOf(" ", i) + 1;
if (i == 0) break;
}
return null;
}
function SetCookie (name, value) {
var argv = SetCookie.arguments;
var argc = SetCookie.arguments.length;
var expires = (argc > 2) ? argv[2] : null;
var path = (argc > 3) ? argv[3] : null;
var domain = (argc > 4) ? argv[4] : null;
var secure = (argc > 5) ? argv[5] : false;
document.cookie = name + "=" + escape (value) +
((expires == null) ? "" : ("; expires=" + expires.toGMTString())) +
((path == null) ? "" : ("; path=" + path)) +
((domain == null) ? "" : ("; domain=" + domain)) +
((secure == true) ? "; secure" : "");
}
function DeleteCookie (name) {
var exp = new Date();
exp.setTime (exp.getTime() - 1);
var cval = GetCookie (name);
document.cookie = name + "=" + cval + "; expires=" + exp.toGMTString();
}

</script>
