element 'script' missing required attribute 'type' 

but actual way in refered line on different sites.

i have refered addess different sites.

is address wrong? or

i have written in wrong way?

please me.

protocol-less paths inherit protocol of current document when opened in browser, work when page opened through http/https protocols.

therefore assume vs interprets protocol-less path local one, not found.

you can check cdn url correct opening link directly through either http/https protocols:

http://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js
https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js

as type attribute, see why write <script type=“text/javascript”> when mime type set server?

in sum, browsers since netscape 2 default script tags javascript, long server sends correct mime work fine. however, wouldn't validate under w3c's html4 mode. in html5, valid omit type attribute commented @elclanrs.
