Guide on getting a website name from a URL using Javascript

Is there a simple method to extract the site name from a URL string?

For example:

http://www.mysite.com/mypath/mypage -> www.mysite.com
http://mysite.com/mypath/mypage     -> mysite.com

The JavaScript code runs on the mongodb CLI side, not within a browser.

Answer №1

Give this a shot:

siteUrl = "http://www.testsite.com/testpath/testpage";

siteProtocol; // => "http:"
siteDomainName; // => "testsite.com" // desired website name

The window.document.location.href contains the page's URL, and the

window.document.location.hostname
holds the website's domain name.

Therefore,

console.log(window.document.location.hostname); // will display the domain name on the console

Answer №2

Simple.

document.domain; //Website domain

$("h1").text(); //Heading text

also this

var loc = window.location;

var page = loc.pathname.split("/");
page = page[page.length-1];

alert("Domain: "+loc.hostname);
alert("Page: "+page);

Answer №3

An anchor can be cleverly exploited to extract the desired data from a URL. :D

function getDomain(url) {
  var anchor = document.createElement('a');
  anchor.setAttribute('href', url);

  return anchor.hostname;
}

console.log(getDomain('http://www.mysite.com/mypath/mypage'));
console.log(getDomain('http://mysite.com/mypath/mypage'));

Answer №4

I found success with this particular solution:

urlString.split('/')[2]

Answer №5

Give this a shot:

let website = new URL(site_name)?.hostname?.replace("www.", "")
console.log(website)

Answer №6

To display only the domain name in a reference section of my app, I need to extract it from a URL.

I came across this helpful resource: https://developer.mozilla.org/en-US/docs/Web/API/URL/URL

The URL() constructor creates a new URL object that represents the specified URL.

If the input base URL or resulting URL are invalid, a JavaScript TypeError exception is thrown.

function getDomain(url) {
   return new window.URL(url).hostname;
}

When using `new URl(url)`, you can access various properties:

hash: ""
host: "developer.mozilla.org"
hostname: "developer.mozilla.org"
href: "https://developer.mozilla.org/en-US/docs/Web/API/URL/URL"
origin: "https://developer.mozilla.org"
password: ""
pathname: "/en-US/docs/Web/API/URL/URL"
port: ""
protocol: "https:"
search: ""
