Use aMember Username in JavaScript / GetClicky

Hi GetClicky.com can track visitors by username if I can send the logged in username via javascript.

This is what they say to use:

<script type="text/javascript">
var clicky_custom_session = { username: "bob"};
</script>

How can I change bob to show what ever aMember login_name is currently logged in instead? I can get it via PHP but I don't know how to get the current username via JavaScript.

So why not use php to get username and pass it to a javascript function?

A pain with the quotes and JS but this is what I came up with and it seems to work:

<?php
$amember = $_SESSION['_amember_user']['login'];
print "<script>var clicky_custom_session = {username: ".stripslashes("'")."$amember".stripslashes("'")."};</script>";
?>
