I try to get only the domain name i.e. google.com from javascript

document.location.hostname

This code returns www.google.com.

How can I only get google.com? In this case it would be to either remove the www. or get only the domain name (if there's such a method in javascript).

var host = location.hostname.replace( /www./g, '' );

The 'g' flag is for 'global', which is needed if you want a true gsub (all matches replaced, not just the first).

Better, though, would be to get the full TLD:

var tld = location.hostname.replace( /^(.+.)?(w+.w+)$/, '$2' );

This will handle domains like foo.bar.jim.jam.com and give you just jam.com.
