<head>
<title>my page</title>
   <script type="text/javascript">
   var theVariable = "<?=$_GET['id']?>";
   </script>
</head>

    why the hell not?

    <script type="text/javascript">var theVariable = "<?=$_GET['id']?>";</script>
<script type="text/javascript" src="myfile.js"></script>
    PHP:
    and in myfile you can totally reference theVariable.
