Rewrite

[The Phantom]

How would I re-write this to be more secure? Someone told me this line is now secure.

 

echo'<script>!window.jQuery && document.write(\'<script src="http://code.jquery.com/jquery-1.4.2.min.js"><\/script>\');</script>';

 

UPDATE -

No worries :)

( for others ) No it's a method of a fallback when loading jQuery.

The idea is, load jQuery via some form of CDN ( Google's for example ), then include a variation of the above to load a local copy ( or another CDN if you wish ) in case of failure.

<script src="//[insert cdn copy here]"></script>
<script>!window.jQuery || document.write ( '<script src="[local copy here]"><\/script>')</script>
