Is there a link to the "latest" jQuery library on Google APIs? [duplicate]
I use the following for a jQuery link in my <script> tags:
http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.js
Is there a link to the "latest" version? Something like the following (which doesn't work):
http://ajax.googleapis.com/ajax/libs/jquery/latest/jquery.js
(Obviously not necessarily a great plan to link your code to potentially changing libraries but useful in development.)
Solution 1:
Up until jQuery 1.11.1, you could use the following URLs to get the latest version of jQuery:
- https://code.jquery.com/jquery-latest.min.js - jQuery hosted (minified)
- https://code.jquery.com/jquery-latest.js - jQuery hosted (uncompressed)
- https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js - Google hosted (minified)
- https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.js - Google hosted (uncompressed)
For example:
<script src="https://code.jquery.com/jquery-latest.min.js"></script>
However, since jQuery 1.11.1, both jQuery and Google stopped updating these URL's; they will forever be fixed at 1.11.1. There is no supported alternative URL to use. For an explanation of why this is the case, see this blog post; Don't use jquery-latest.js.
Both hosts support https as well as http, so change the protocol as you see fit (or use a protocol relative URI)

Solution 2:
DO NOT USE THIS ANSWER. The URL is pointing at jQuery 1.11 (and always will).
Credits to Basic for above snippet
http://code.jquery.com/jquery-latest.min.js is the minified version, always up-to-date.
Solution 3:
Be aware that caching headers are different when you use "direct" vs. "latest" link from google.
When using http://ajax.googleapis.com/ajax/libs/jquery/1.3.1/jquery.min.js
Cache-Control: public, max-age=31536000
When using http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js
Cache-Control: public, max-age=3600, must-revalidate, proxy-revalidate
Solution 4:
Don’t Use jquery-latest.js
This file is no longer updated (it'll be on v1.11.1 forever). Furthermore it has a very short cache life, (wiping out the benefits of using a CDN) so you'd be better of selecting a version of jQuery instead.

Solution 5:
Not for nothing, but you shouldn't just automatically use the latest library. If they release the newest library tomorrow and it breaks some of your scripts, you are SOL, but if you use the library you used to develop the scripts, you will ensure they will work.
