How to detect external javascript is been loaded or not?
<p>How we can know with my application whether the user have blocked any external javascript those not allocated on my server, i.e. on my site jquery is loading from jquery.org and if user blocked that site then how can I show a message to that user to allow scripts from jquery.org.</p>

<p>I have found that this things is there on the site of stackoverflow.com when I do block stackoverflow shows me </p>

<blockquote>
  <p>"Stack Overflow requires external JavaScript from another domain,
  which is blocked or failed to load."</p>
</blockquote>

<p>message, so my question is how can I get the idea of external scripts was loaded successfully or not?</p>

<p>Thanks in advance.</p>
