Including Google Hosted jQuery and other JS Libraries


When I’m testing my JavaScript with jQuery, sometimes, I feel lazy to locate on my hard disk where is that jQuery library file.

At the same time, I don’t want to download it on their website. So I thought of hosting it on a server and just specify its URL as a source of my <script> tag.

But then I found out that Google is hosting different JavaScript library for free. So now, I can access the library just by specifying the URL of Google-hosted jQuery library.

Google hosts several open-source library which includes:

Chrome Frame


Ext Core


jQuery UI





Yahoo! User Interface Library (YUI)

WebFont Loader

So now, here’s how I include a jQuery library on my scripts.

<script src="//"></script>

You may also use google.load function if you want. But you have to get your own API key. So I prefer accessing it in direct path (script above).

Here’s a simple slide and toggle demo, with jQuery hosted by google.

Well actually, jQuery site also provide their script.

<script src=""></script>

There are many debates whether to host your jQuery on Google or not. You may also read this article and its comments.
