You've Got Mail (Except It's a Domain, Not a Love Letter): Unveiling the URL in JavaScript
Ah, JavaScript. The language of the web, the master of manipulation, the... detective extraordinaire when it comes to finding that elusive domain name hiding within a URL?
Well, maybe "extraordinaire" is a tad strong. But fear not, fellow coders, because unearthing this digital nugget is a breeze! Today, we'll delve into the not-so-secret world of JavaScript and its handy tools for snatching that domain URL like a boss.

| How To Get Domain Url In Javascript |
Meet the Sheriff in Town: window.location
First things first, if you want to know the domain of the very webpage you're currently inhabiting (because, hey, self-awareness is important!), then look no further than the trusty window.location object. This sheriff holds all the keys to the current URL kingdom, and with a simple property access, we can snag that domain like a tumbleweed in a dusty Western.
Here's the magic trick:
Tip: Don’t skip — flow matters.
const domain = window.location.hostname;
console.log(domain); // Boom! There's your domain name
Hold on, partner! What about that fancy URL I found on the internet?
Easy there, cowboy. window.location only works for the current page. But fret not, for JavaScript has another ace up its sleeve: the URL constructor!
Introducing the URL Wrangler: The URL Constructor
This sophisticated fella lets you wrangle any URL you throw at it, dissecting it and revealing its inner secrets, including, you guessed it, the domain name!
QuickTip: Note key words you want to remember.
Let's say you have a URL stored in a variable called mysteryURL:
const mysteryURL = "https://www.super-secret-domain.com/hidden-treasure";
Just like wrangling a wild mustang, you can use the URL constructor to tame this URL:
 |
const urlObject = new URL(mysteryURL);
const domain = urlObject.hostname;
console.log(domain); // And voila! The super-secret domain is exposed!
Now, that's what I call a power couple!
Tip: Focus on sections most relevant to you.
By combining window.location for the current page and the URL constructor for any URL, you have the ultimate domain-hunting toolkit at your disposal.
But Wait, There's More! (Because Bonus Points Are Always Cool)
While the methods above are tried-and-true, there's another way to skin this digital cat – using document.createElement('a'). This might sound a bit like wrangling a cat with a lasso (not recommended!), but it works!
Here's the rodeo:
Tip: Stop when you find something useful.
const url = "https://yet-another-domain.com/adventure-awaits";
const anchor = document.createElement('a');
anchor.href = url;
const domain = anchor.hostname;
console.log(domain); // And yep, the domain is caught!
This method creates a temporary anchor element (<a>) and sets its href attribute to the URL. Then, we can access the hostname property of the anchor element to grab the domain name.
So, which method should you use?
Well, that depends, partner! If you're dealing with the current page's URL, window.location is your best bet. For any URL you have on hand, the URL constructor is the clear winner. And if you're feeling fancy (or just want to try something new), the document.createElement('a') method might be your huckleberry.
Now, go forth and conquer those URLs! Remember, with a little JavaScript know-how, you can be the domain- wrangling champion of the digital frontier.
