Get The Current Domain Name With Javascript (Not the path, etc.)

Question

I plan on buying two domain names for the same site. Depending on which domain is used I plan on providing slightly different data on the page. Is there a way for me to detect the actual domain name that the page is loading from so that I know what to change my content to?

I've looked around for stuff like this but most of it doesn't work the way I want it to.

For instance when using

document.write(document.location) 

on JSFiddle it returns

http://fiddle.jshell.net/_display/

i.e. the actual path or whatever that is.

Answer 1

How about:

window.location.hostname 

The location object actually has a number of attributes referring to different parts of the URL

Answer 2

Let's suppose you have this url path:

http://localhost:4200/landing?query=1#2

So, you can serve yourself by the location values, as follow:

window.location.hash: "#2" ​ window.location.host: "localhost:4200" ​ window.location.hostname: "localhost" ​ window.location.href: "http://localhost:4200/landing?query=1#2" ​ window.location.origin: "http://localhost:4200" ​ window.location.pathname: "/landing" ​ window.location.port: "4200" ​ window.location.protocol: "http:"  window.location.search: "?query=1" 

Now we can conclude you're looking for:

window.location.hostname
