Cookies help with coding!

[metallifan15]

Alright, I have a basic code I found at JavaScript Kit

I would kindly like some help getting code to open an alert box when they close or leave a certain domain. The following script is from the above mentioned site.

<script type="text/javascript">
//Get cookie routine by Shelley Powers
function get_cookie(Name) {
var search = Name + "="
var returnvalue = "";
if (document.cookie.length > 0) {
offset = document.cookie.indexOf(search)
// if cookie exists
if (offset != -1) {
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 setcolor(what){
document.body.style.backgroundColor=what
document.cookie="bgcolor="+what
}

if (get_cookie("bgcolor")!="")
document.body.style.backgroundColor=get_cookie("bgcolor")

</script>

Is there a way to modify this section

function setcolor(what){
document.body.style.backgroundColor=what
document.cookie="bgcolor="+what
}

if (get_cookie("bgcolor")!="")
document.body.style.backgroundColor=get_cookie("bgcolor")

or whichever section needs the alert code, so that it calls up an alert box?

Please help. I'm not a JS expert I only have basic knowledge and right now I do not have resources or time to fully "learn" the expansive amount of JS knowledge to create this code myself.

Thanks!

document.cookie="bgcolor="+what needs to be escaped, You have no expiry or other important bits that go with a cookie.

If you search this forum for cookies, you will find plenty of examples that you can use and modify for your needs.
