Utility functions for domain strings.
Download domo.js and include it in your HTML file by sticking the following line in the <head> section:
<script src="<PATH>/<TO>/<JAVASCRIPTS>/domo.js" type="text/javascript"></script>
Now you can use Domo's functions on domain strings. Try it in code or in a javascript console:
> Domo.canonicalize("www.ebay.com")
=> "ebay.com"
> Domo.canonicalize("boats.ebay.co.uk")
=> "ebay.co.uk"
> Domo.canonicalize("edition.cnn.com")
=> "cnn.com"
> Domo.stripUrl("http://www.cnn.com/news/last-week/main.html")
=> "www.cnn.com"
The unit tests are written in Pavlov, a QUnit backed framework for BDD. To run the tests, just fire up a browser and open spec/domo.specs.html.
