Cookie Warning that visitor is leaving site

Hi there,
Has anyone seen a cookie script that will warn a visitor that they are leaving a specific site. i.e. when they click on a link that is external to mysite.com. We want a cookie that (uses an alert?) to warn the visitor that they are about to leave our site and go to another site.

Any help sure appreciated.

You can easily do this by walking through a collection of all the <a href> nodes in the current page... and attaching an onclick to them if their url is considered "external".

Look at using document.getElementsByTagName('a') to get a collection of all the <a href> nodes. You can then use length() to find out how many there are - so you can set up a loop. Then you can examine the href src for each - maybe assuming that if they start with http:// then they are external... and attaching an onlick to them.

Cheers,
Jeff

No can do. Cookies cannot warn people - they are data storage. You'll have to use another method that has nothing to do with cookies, much like the one Jeff has suggested above.

Hey Bob...

Here is a sample page that shows what I was talking about. If the user has javascript it will work... otherwise it won't interfere with anything.
Code: 
<html>
<head><title>Example</title>
<script type="text/javascript">
function alertUser() {
	if (this.href.indexOf('http')==0 || this.href.indexOf('[URL unfurl="true"]www')==0)[/URL] {
		alert('You are leaving our site now - have a safe journey!');
	}
}

function initPage() {
	var hrefs = document.getElementsByTagName('a');
	for (var i=0,max=hrefs.length; i<max; i++)
		hrefs[i].onclick = alertUser;
}

window.onload = function () { initPage(); };
</script>
</head>

<body>
<p>There are some links on this page...</p>
<ul>
	<li><a href="/contact.html">Contact</a></li>
	<li><a href="/intro.html">Introduction</a></li>
	<li><a href="/products.html">Products</a></li>
	<li><a href="/services.html">Services</a></li>
	<li><a href="[URL unfurl="true"]http://www.google.com">Google</a></li>[/URL]
	<li><a href="[URL unfurl="true"]http://www.google.co.uk">Google[/URL] UK</a></li>
</ul>
</body>
</html>

Cheers,
Jeff

Hi Jeff,
Thanks very much. I can take a look at this and learn from it. Really appreciate your help.

No worries. More and more you will see that kind of code... something that adds functionality to existing HTML - but only loading that functionality after the page has loaded (and when javascript is enabled). This is one of the fundamentals driving the whole "Web 2.0" buzz - seperate out the markup, the presentation (css) and extra "enhanced" functionality so that the code remains usable across many different applications and uses.

Let us know how you go!
Jeff
