How to create JS message with cookie

[Jim Poor]

I had one a while back but can't find it now.

I need to put a "We'll be closed" message on my site that only pops up once per day or even once every two days for each visitor.

Right now, what I have pops up every visit, which could get rather annoying.

See what I have here: Jim Poor Photography

Anyone know how to add a cookie to it so it only pops up once per day or every two days?

Wish I knew too. Guess that's what we get for having opinions and giving out free advice.

I'm not a coder, but this might help, pop up only once??? - CodingForums.com

Thanks. I found that one, but reading through it made my head spin

try this...Paste this code into an external ********** file named: onlyPopupOnce.js

var expDays = 1; // number of days the cookie should last

var page = "only-popup-once.html";
var windowprops = "width=300,height=200,location=no,toolbar=no,menuba r=no,scrollbars=no,resizable=yes";

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();
}

var exp = new Date();
exp.setTime(exp.getTime() + (expDays*24*60*60*1000));

function amt(){
var count = GetCookie('count')
if(count == null) {
SetCookie('count','1')
return 1
} else {
var newcount = parseInt(count) + 1;
DeleteCookie('count')
SetCookie('count',newcount,exp)
return count
}
}

function getCookieVal(offset) {
var endstr = document.cookie.indexOf (";", offset);
if (endstr == -1)
endstr = document.cookie.length;
return unescape(document.cookie.substring(offset, endstr));
}

function checkCount() {
var count = GetCookie('count');
if (count == null) {
count=1;
SetCookie('count', count, exp);
window.open(page, "", windowprops);
} else {
count++;
SetCookie('count', count, exp);
}
}

window.onload=checkCount;

Then, paste this code into the HEAD section of your HTML document.

i'm sure "someone" else will have a better answer...

I just remembered why I employ programmers to do my stuff

[Mr Guy]

I can help you with that, if you haven't already solved it.

Conceptually, you need to store the date as your cookie, and then find the differences between both dates, and do modulus math, and only pop it up when the modulus math comes out 0.

Taking a quick look at your site to give specific advice.

*Edit*

Yeah, I thought you meant you had it working but it was popping up too often. The code posted above ought to be very close to what you need, except for:

window.open(page, "", windowprops);

which you'll need to replace with your alert.

Thanks. That's the code that confused the crap out of me.

The last one I had, I only had to paste the code into my footer (to load after the site) and there was no reference to an external doc.

I know I saved it but just can't remember where or what the file was called. :-(

Just a sidenote, but could one of the mods/admins PLEASE remove the word that JS stands for from the censorship list? It's not that funny, and it's freaking annoying that everytime you type in ********** the damn word gets asterisked out. Especially with code examples, or when you're asking for website help.
