Disqus is a great service that takes all comments-related scripts out of your shoulders, but it doesn't work in real XHTML applications (when the one is served with application/html+xml content
type). Disqus team has even stated it clear, that they WILL NOT care about XHTML support.
But it's not really a big deal - Disqus is loaded within <iframe> so all that needs to be XHTML-compatible is a loading script. Disqux is a drop-in replacement for original embed.js script that will allow to load Disqus in XHTML application.
The source is just un-minified version of that embed.js, so all the methods and variables names are still obfuscated - it is just formated the way it can be easier to debug in case of more XHTML incmpatibilities.
Simply replace file URL and you can enjoy Disqus comments in your XHTML application:
<div id="disqus_thread"></div>
<script type="text/javascript">
var disqus_shortname = 'your-short-name';
(function() {
var dsq = document.createElement('script'); dsq.type = 'text/javascript'; dsq.async = true;
dsq.src = '/path/to/your/disqus.js'; // THIS IS ALL YOU NEED TO DO
(document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(dsq);
})();
</script>
<a href="http://disqus.com" class="dsq-brlink">comments powered by <span class="logo-disqus">Disqus</span></a>You can see example on my blog - http://wrzasq.pl/.
You probably have minifying script in your application deploy flow, so the main file is distributed in un-obfuscated way, so you can use it in your development environment. If you don't want to implement own minifying flow however, there is simple Makefile in project directory which contains minification tasks.
If you want to know what's the difference between this script and original embed.js the answer is veeeeery short - just one space. That's right! Just one space and this script works perfectly with XHTML applications - can't understand why it's so big deal for Disqus team :/. The fix is located here - in original file there is no space between attributes and it causes DOM paring errors when injecting this snippet into innerHTML property of container.
