Hi, I was wondering which method is best to use for "CDN's jQuery fall back to local" ?
Method 1:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script>window.jQuery || document.write('<script src="assets/js/jquery-1.8.3.min.js"></script>')</script>
Method 2:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script>!window.jQuery && document.write('<script src="assets/js/jquery-1.8.3.min.js"></script>')</script>
Method 3:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">
if (typeof jQuery == 'undefined') {
document.write(unescape(""));
}
</script>
Thank you!
