Question
Problem saving cookie! Should be easy!
I'm using IE5 and I want to save a cookie, that records what the browser dimensions were when it closed. Then when you open that page, it can remember it. But for some reason it's only saving the first cookie name-value pair. The onLoad and onUnload seem to be working strangley too. Hope you can help! Here's the code:
<html>
<head>
<title>Page Size</title>
<link rel="stylesheet" type="text/css" href="../css/map.css">
<meta name="Author" content="Ben Weeks">
<script language="JavaScript">
<!-- // Hide from incompatible brosers
function getPageSize()
{
alert("boo!");
document.write("<p>" + document.cookie + "</p>");
HKMapWidth = getCookieData('HKMapWidth'
HKMapHeight = getCookieData('HKMapHeight
document.write("<p>HKMapWi
}
function savePageSize()
{
alert("saving cookie!");
// Find the browser dimensions.
var browserWidth = document.body.offsetWidth;
var browserHeight = document.body.offsetHeight
// Set the expirey date one year from now. Must be in GMT format.
var exp = new Date();
var oneYearFromNow = exp.getTime() + (365 * 24 * 60 * 60 * 1000);
exp.setTime(oneYearFromNow
// If cookie already exists it will over-ride the old value, if it doesn't it will create a new cookie.
// NB See p308 in the JavaScript Bible 3rd Edition for more information.
document.cookie = "HKMapWidth=" + browserWidth + ";HKMapHeight=" + browserHeight + ";expires=" + exp.toGMTString();
}
function getCookieData(label)
{
// this function can be found on p311 of the JavaScript Bible 3rd Edition.
// More cookie retrieving functions can be found at:
// http://www.hidaho.com/cook
label = label + "="; // Assume cookie is in the format of cookieName=cookieValue, i.e. no spaces.
var labelLen = label.length;
var cookieLen = document.cookie.length;
var i = 0;
while (i < cookieLen)
{
var j = i + labelLen;
if (document.cookie.substring
{
strEnd = document.cookie.indexOf(";
if (strEnd == -1)
{
strEnd = document.cookie.length;
}
return unescape(document.cookie.s
}
i++
}
return "";
}
// -->
</script>
<body onLoad="getPageSize()" onUnload="savePageSize()">
</body>
</html>

Still seems to do the same, see www.webtechy.co.uk/pagesiz
And then look for the cookie www.webtechy.co.uk in your internet temporary files location (IE).
i.e. it's just saving:
HKMapWidth
1124
www.webtechy.co.uk/
0
2763775744
29482136
738584544
29408711
*
in the cookie.
OK, I've now got it working - thanks! One last thing - if I place this on a server that may also use cookies, will my code affect any other cookies that they may have? See:
www.webtechy.co.uk/openpag
for how this is actually being used.
Thanks again!

ou can use the following function if you'd like
function setCookie (name,value,expires,path,t
var theCookie = name + "=" + escape (value) +
((expires) ? "; expires=" + expires.toGMTString() : "") +
((path) ? "; path=" + path : "") +
((theDomain) ? "; domain=" + theDomain : "") +
((secure) ? "; secure" : "");
document.cookie = theCookie;
}
