Refer-a-friend script

I'm trying to create one, but frames are my enemy

[wintercornuk]

I've got a basic TAF email link on each of my book pages so that visitors can tell a friend.

I want to have a much slicker one, so I created a little bit of html and it works OK. Except, I want to be able to show the current page URL and send that as part of the form to the recipients email address.

How can this be done in js?

Something like this?
[I don't know how you're entering the friend's email address]

<script language="JavaScript" type="text/javascript">
function doMail()
{
  var loc = location.href
  window.location = "mailto:you@yours?body="+loc
}
</script>
<a href="mailto:[e-mail]" onclick="doMail();return false">mail page address</a>
