It's impossible. Chrome's security policy will not allow this.
Option 1:
Build the javascript that you want to download remotely yourself and relate to it relatively.
<script type="text/javascript" src="/my/assets/js/jquery/1.10.2/jquery.min.js"></script>
The resource request on your own server is protocol independent
Option 2:
Use a CDN that supports SSL. (E.g. Google)
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
A relative protocol entry can be used to request a source with an appropriate protocol depending on the protocol that uses the current resource (see above).
Side note
Chrome uses the "-allow-running-insecure-content" command-line option, which skips checking for insecure content.
I highly recommend not using it because you cannot expect your users to set this option.
