will return the host name and port var host   window location host    or possibly var host   window location protocol    quot    quot    window location host   or if you like concatenation var protocol   location protocol  var slashes   protocol concat  quot    quot    var host   slashes concat window location host       or as you probably should do var host   location protocol concat  quot    quot   concat window location host       the above is the same as origin  e g   quot https   stackoverflow com quot  var host   window location origin   If you have or expect custom ports use window location host instead of 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

I like this one depending of purpose  window location href split      2      localhost 17000    always domain   port   You can apply it on any url-string  var url    http   localhost 17000 sub1 sub2 mypage html q 12   url split      2      localhost 17000  url split      url split      length-1      mypage html q 12    Removing protocol  domain  amp  path from url-string  relative path   var arr   url split       if  arr length gt 3           arr splice 3  arr length  join           sub1 sub2 mypage html q 12
