Google CDN jQuery加载回退

Posted 2021-02-24

This code snippet fetches the very latest minified version of jQuery from Google's CDN. If this is not available, we revert to a locally stored version (current version at time of publish was 1.7.1 - update this to suit going forward).

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script>!window.jQuery && document.write('<script src="js/jquery-1.7.1.min.js"></script>')</script>
