Can I just store all my scripts, etc. on another host and reference them on my SS6 site?

I'm having some trouble with something that involves multiple folders that need to be put in the root folder of my site. I put them in another site I have hosting with and I tried linking the stylesheet and .js file to reference the other site, but then I'm confused about the last 2 bits of implementation, which are

<script type="text/javascript">
$(document).ready(function() {
$('.demo a').noApishare({'set': '1'});
</script>

==

and then of course the HTML code - how do I let it know it's referencing data on another site?

<ul class="basic">
<li><a data-service="facebook"></a> </li>
<li><a data-service="twitter"></a></li>
<li><a data-service="pinterest"></a></li>
<li><a data-service="google-plus"></a></li>
<li><a data-service="linkedin"></a></li>
<li><a data-service="stumbleupon"></a></li>
<li><a data-service="reddit"></a></li>
<li><a data-service="tumblr"></a></li>
<li><a data-service="email"></a></li>
</ul>

I've been able to make other custom scripts work but I haven't used one with this type of structure on SS6 yet.
