javascript - skipping http protocol in url doesn't load the script file -

i open index.html in browser file:/// , scripts no protocol name not loaded.

<script type="text/javascript" language="javascript" src="//code.jquery.com/jquery-1.10.2.min.js"></script> 

this doesn't work in mozilla 36.0.4, chrome on machine.

on using node-static server, jquery file gets loaded successfully.

can skip protocol names in script links , still open file file:///?

no, need edit index.html files , add 'http' or 'https' script tags.

skipping protocol means using same protocol page loaded (which useful instance if allow both http , https). in case browser interpret above as:

<script type="text/javascript" language="javascript" src="file:///code.jquery.com/jquery-1.10.2.min.js"></script>
