jquery, domain, get URL

Question

How can I get the domain name with jquery ??

Answer 1

If you need from string, like me, use this function - it really works.

function getHost(url)
{
    var a = document.createElement('a');
    a.href = url;
    return a.hostname;
}

But note, if there is a subdomain (e.g. www.) in the URL it will get returned with the hostname. Conversely, if there is no subdomain the hostname will not have one either.

Answer 2

var part = location.hostname.split('.');
var subdomains = part.shift();
var upperleveldomains = part.join('.');

second-level-domain, you might use

var sleveldomain = parts.slice(-2).join('.');

Answer 3

check this

alert(window.location.hostname);

this will return host name as www.domain.com

Answer 4

jQuery is not needed, use simple javascript:

document.domain

Answer 5

EDIT:

If you don't need to support IE10, you can simply use: document.location.origin

Original answer, if you need legacy support

You can get all this and more by inspecting the location object:

location = {
  host: "stackoverflow.com",
  hostname: "stackoverflow.com",
  href: "http://stackoverflow.com/questions/2300771/jquery-domain-get-url",
  pathname: "/questions/2300771/jquery-domain-get-url",
  port: "",
  protocol: "http:"
}

so:

location.host 

would be the domain, in this case stackoverflow.com. For the complete first part of the url, you can use:

location.protocol + "//" + location.host

which in this case would be http://stackoverflow.com

No jQuery required.
