如何从url获取子域

Question

I have a url like http://abc.xyz.com . I just want 'http://abc' part, But I am getting 'http://abc.xyz.com'

I tried this:

windw.location.origin

Do I need to write some extra method to get the first part of url or is there something any window method which will do the same?

Answer 1

You can split it by . and take the first element

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

Example:

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

Answer 2

"http://abc.xyz.com".split(".")[0]
// or
var url = "http://abc.xyz.com";
url.split(".")[0]

returns "http://abc"

Answer 3

It's as simple as that: [subdomain] = 'https://abc.def.xyz'.split('.');

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