One: Generally, as pointed out in the comments, this is a bad idea for your code, because things will break. https://blog.jquery.com/2014/07/03/dont-use-jquery-latest-js/
Two: There were once links to the "latest" jQuery libraries at the Google API - i.e., using the file name jquery-latest.js
- but no more: http://stackoverflow.com/questions/12608242/latest-jquery-version-on-googles-cdnhttps://stackoverflow.com/questions/12608242/latest-jquery-version-on-googles-cdn
We know that http://code.jquery.com/jquery-latest.js is abused because of the CDN statistics showing it’s the most popular file. That wouldn’t be the case if it was only being used by developers to make a local copy.
We have decided to stop updating this file, as well as the minified copy, keeping both files at version 1.11.1 forever.
The Google CDN team has joined us in this effort to prevent inadvertent web breakage and no longer updates the file at http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.js. That file will stay locked at version 1.11.1 as well.
