jquery, domain, get URL

Question

You don't need jQuery for this, as simple javascript will suffice:

alert(document.domain);

See it in action:

console.log("Output;");  
console.log(location.hostname);
console.log(document.domain);
alert(window.location.hostname)

console.log("document.URL : "+document.URL);
console.log("document.location.href : "+document.location.href);
console.log("document.location.origin : "+document.location.origin);
console.log("document.location.hostname : "+document.location.hostname);
console.log("document.location.host : "+document.location.host);
console.log("document.location.pathname : "+document.location.pathname);

For further domain-related values, check out the properties of window.location online. You may find that location.host is a better option, as its content could differ from document.domain. For instance, the url http://192.168.1.80:8080 will have only the ipaddress in document.domain, but both the ipaddress and port number in location.host.

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.

Similar to the answer before there there is

location.host

The location global has more fun facts about the current url as well. ( protocol, host, port, pathname, search, hash )

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.

You can use below codes for get different parameters of Current URL

alert("document.URL : "+document.URL);
alert("document.location.href : "+document.location.href);
alert("document.location.origin : "+document.location.origin);
alert("document.location.hostname : "+document.location.hostname);
alert("document.location.host : "+document.location.host);
alert("document.location.pathname : "+document.location.pathname);

jQuery is not needed, use simple javascript:

document.domain
