What's the difference between using

if (document.domain.toLowerCase().indexOf(domainName) != -1)

and

if(window.location.href.match(/://(.[^/]+)/)[1].toLowerCase().indexOf(domainName) != -1)

and

if(window.location.hostname.toLowerCase().indexOf(domainName) != -1)

I'm just trying to match on a certain domainName and want to use the best approach.

Best and most readable would be:

if(location.hostname == mysite.com){



}

Update:

Or as Patrick pointed out if you are only looking for part of the domain name I would use match.

if(location.hostname.match('mysite')){} // will return null if no match is found
