Parsing inline javascript variable to script src as parameter

Question

I'm new to JS, so please bear with me if this question might not make sense.

Is it possible to parse an inline js value to a js src value?

Suppose I have this inline js.

<script>
    window.foo = window.foo || {};
    window.foo.cam = { 'status';'logged-out'};
</script>

This is the javascript src which I like to parse the above value to to %value%.

<script src="http://bar.com/js.php?position=bottom&login_status=%value%"></script>

It's possible to do if you dynamically add the script tag to the DOM with Javascript:

<div id="s_tag_container"></div>
<script type="text/javascript">
    window.foo = window.foo || {};
    window.foo.cam = {'status': 'logged-out'};
    var s_tag = document.createElement('script');
    s_tag.src = 'http://bar.com/js.php?position=bottom&login_status='+window.foo.cam.status;
    document.getElementById('s_tag_container').appendChild(s_tag);
</script>
