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

How about:

window.location.hostname

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

Get the current URL with JavaScript?

Use:

window.location.href

As noted in the comments, the line below works, but it is bugged for Firefox.

document.URL

See URL of type DOMString, readonly.

How to get the host URL using JavaScript from the current page

// will return the host name and port
var host = window.location.host; 

or possibly

var host = window.location.protocol + "//" + window.location.host;

or if you like concatenation

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

// or as you probably should do
var host = location.protocol.concat("//").concat(window.location.host);

// the above is the same as origin, e.g. "https://stackoverflow.com"
var host = window.location.origin;

If you have or expect custom ports use window.location.host instead of window.location.hostname

How to get current domain name in ASP.NET

Using Request.Url.Host is appropriate - it's how you retrieve the value of the HTTP Host: header, which specifies which hostname (domain name) the UA (browser) wants, as the Resource-path part of the HTTP request does not include the hostname.

Note that localhost:5858 is not a domain name, it is an endpoint specifier, also known as an "authority", which includes the hostname and TCP port number. This is retrieved by accessing Request.Uri.Authority.

Furthermore, it is not valid to get somedomain.com from www.somedomain.com because a webserver could be configured to serve a different site for www.somedomain.com compared to somedomain.com, however if you are sure this is valid in your case then you'll need to manually parse the hostname, though using String.Split('.') works in a pinch.

Note that webserver (IIS) configuration is distinct from ASP.NET's configuration, and that ASP.NET is actually completely ignorant of the HTTP binding configuration of the websites and web-applications that it runs under. The fact that both IIS and ASP.NET share the same configuration files (web.config) is a red-herring.

Is there any solution for getting current domain name by Reactjs?

This isn't React specific.

Just look at window.location:

alert(window.location.hostname)
