var host = window.location.hostname;

or possibly

var host = "http://"+window.location.hostname;

or if you like concatenation 

var http = location.protocol;
var slashes = http.concat("//");
var host = slashes.concat(window.location.hostname);

To get the hostname: location.hostname

But your example is looking for the scheme as well, so location.origin appears to do what you want in Chrome, but gets not mention in the Mozdev docs. You can construct it with

location.protocol + '//' + location.hostname

If you want the port number as well (for when it isn't 80) then:

location.protocol + '//' + location.host

Good answer, i remove mine – Ibu May 18 '11 at 8:45
Firefox 4 doesn't seem to have it, though Chrome 12 does. Is it defined in a specification? – Delan Azabani May 18 '11 at 8:46
@Delan — just noticed that and was editing while you commented. – Quentin May 18 '11 at 8:46

Try this

alert (window.location.hostname)

location.protocol + "//" + location.host if you want to include the port, helpful for when you're working on your local computer with a URL like this: localhost:1329/Home/Login
