Help with pop up window script

[jilly23]

I am using the following script on my site to load a popup ad.. However I want it to open only once...Not every visit to the page.. How do I configure the script to do this?

Here it is -

<script>

//Popup Window Script
//By JavaScript Kit (http://javascriptkit.com)
//JavaScript tutorials and over 400+ free scripts

function openpopup(){
var popurl="ccad.html"
winpops=window.open(popurl,"","width=531,height=370,")
}

function get_cookie(Name) {
var search = Name + "="
var returnvalue = "";
if (document.cookie.length > 0) {
offset = document.cookie.indexOf(search)
if (offset != -1) { // if cookie exists
offset += search.length
// set index of beginning of value
end = document.cookie.indexOf(";", offset);
// set index of end of cookie value
if (end == -1)
end = document.cookie.length;
returnvalue=unescape(document.cookie.substring(offset, end))
}
}
return returnvalue;
}

function loadornot(){
if (get_cookie('poppedup')==''){
openpopup()
document.cookie="poppedup=yes"
}
}

loadornot()
</script>

That should work if they don't close their browser down, open it back up and go to the page. The script sets a cookie so that is won't open up again within the same browser session. Is that not working?

[jilly23]

Yes it is working for the session but I do not want a session cookie I want it show only once ever and then not again...

You will need to add an expiration date to the cookie. try this link for an explanation on how to do it:

It is old, but still relavent.

Thanks for the information - the one page ont he site keeps crashing my browser...

How would I configure the code that I have? Or would I have to use a totally different script?

Thanks for all your help!
