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.)
Up until jQuery 1.11.1, you could use the following URLs to get the latest version of jQuery:
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)

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
Use:
<script type="text/javascript" src="//www.google.com/jsapi"></script>
<script type="text/javascript">
//<![CDATA[
google.load("jquery", "1");
//google.load("jqueryui", "1");
//google.load("swfobject", "1");
//]]>
</script>
Note: The above snippet will stick to 1.7.1 or 1.11.1.
My advice for production is to hard code the CDN jQuery version: <script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
You can find the latest Libraries of Google CDN here: https://developers.google.com/speed/libraries/
Or use the jQuery CDN: https://code.jquery.com/
