Get The Domain Name Of The Subdomain Javascript

Are you looking to retrieve the domain name of a subdomain in JavaScript, but not sure where to start? Don't worry, we've got you covered. In this guide, we'll walk you through the steps to get the domain name of a subdomain using JavaScript.

To get the domain name of a subdomain in JavaScript, you can leverage the built-in functionality provided by the browser's `URL` object. This object allows you to easily parse and extract different parts of a URL, including the domain name.

Here's a simple example to demonstrate how you can extract the domain name from a subdomain using JavaScript:

// Define the URL of the subdomain
const subdomainUrl = 'https://subdomain.example.com/path/to/resource';

// Create a new URL object with the subdomain URL
const url = new URL(subdomainUrl);

// Get the domain name of the subdomain
const domainName = url.hostname;

// Output the domain name
console.log('Domain Name:', domainName);

In this code snippet, we first define the URL of the subdomain `subdomainUrl`. We then create a new `URL` object by passing the subdomain URL as an argument. By accessing the `hostname` property of the `URL` object, we can retrieve the domain name of the subdomain.

When you run this code, you should see the domain name of the subdomain printed to the console.

If you're working with a subdomain URL that includes a path or query parameters, you can still use the same approach to extract the domain name:

// Define a subdomain URL with a path
const subdomainUrlWithPath = 'https://subdomain.example.com/path/to/resource?query=123';

// Create a new URL object with the subdomain URL
const urlWithPath = new URL(subdomainUrlWithPath);

// Get the domain name of the subdomain
const domainNameWithPath = urlWithPath.hostname;

// Output the domain name with path
console.log('Domain Name with Path:', domainNameWithPath);

By following these steps, you can easily retrieve the domain name of a subdomain in JavaScript using the `URL` object. This method provides a straightforward way to parse URLs and extract specific components like the domain name.
