Tips for extracting subdomains from URLs

Looking for a way to extract only the 'http://abc' part from a URL like http://abc.xyz.com, unfortunately getting the full 'http://abc.xyz.com'.

I attempted using:

windw.location.origin

Do I need to implement an additional method to achieve this extraction, or is there perhaps another window method that can accomplish the same?

Answer №1

To divide it, use the . as a delimiter and select the initial part

window.location.origin.split('.')[0]

For instance:

console.log(window.location.origin);
console.log(window.location.origin.split('.')[0]);

Answer №2

"http://example.com".split(".")[0]
// or
var link = "http://example.com";
link.split(".")[0]

results in "http://example"

Answer №3

It doesn't get much easier than this:

[subdomain] = 'https://abc.def.xyz'.split('.');

var siteLink = 'https://abc.def.xyz';
[subdomain] = siteLink.split('.');
console.log(subdomain);
