Cookie Option

[bkendra5]

I am volunteering at a hospital and working on the intranet. They want an option to have a pop up message but they only want it to pop up once or twice, and then be able to change the content and have it re pop-up.
Example: week1 how to properly wash your hands
Week2: system wide meeting on thursday dont forget. etc etc..
I am not very good in Java. but this is what i have so far. Can anyone point me in the right direction. Greatly appreciated.
also we use active directory, so i dont know if we could maybe pull by user name? Thanks


[code=javascript]
var username = GetCookie('user name');

if (username == null) {
username = prompt('Please enter your name (otherwise press cancel)',"WebSu rfer");
if (username == null) {
alert('Its ok if you dont want to tell me your name');
username = 'WebSurfer';
} else {
pathname = location.pathna me;
myDomain = pathname.substr ing(0,pathname. lastIndexOf('/')) +'/';
var largeExpDate = new Date ();
largeExpDate.se tTime(largeExpD ate.getTime() + (365 * 24 * 3600 * 1000));
SetCookie('user name',username, largeExpDate,my Domain);
}
}

function getCookieVal (offset) {
var endstr = document.cookie .indexOf (";", offset);
if (endstr == -1)
endstr = document.cookie .length;
return unescape(docume nt.cookie.subst ring(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.cooki e.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.argum ents;
var argc = SetCookie.argum ents.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.toGMTSt ring())) +
((path == null) ? "" : ("; path=" + path)) +
((domain == null) ? "" : ("; domain=" + domain)) +
((secure == true) ? "; secure" : "");

Cookies would only work for one particular computer/browser. If you need this over a number of computers/users, use server-side code.
