• Use Window.location.href there u will get the full url as array (may be ) then u can split it and check what u need to check – sayalok Commented Nov 11, 2018 at 14:40

You can use the global URL:

const url = new URL('', 'https://google./blabla ');
console.log(url.hostname); // "google."
console.log(url.pathname); // "/blabla" 

You can check url.pathname, and if there is no pathname, it will return /.

const url = new URL('', 'https://google. ');
console.log(url.hostname); // "google."
console.log(url.pathname); // "/"

You can use regex to check URLs content. The /^https?:\/\/[^\/?]+\/$/g match any URL that start with http and end with domain suffix and /

var url = 'https://google./';
/^https?:\/\/[^\/?]+\/$/g.test(url) // true

function testURL(url){
  return /^https?:\/\/[^\/?]+\/$/g.test(url);
}
console.log(testURL('https://google./'));
console.log(testURL('https://docs.google./'));
console.log(testURL('https://google./blabla'));  

You Can use Window.location to get all these details

Ex: for this question:

window.location.hostname  ==>> // "stackoverflow."

window.location.pathname == >> ///questions/53249750/how-to-check-whether-url-only-contains-the-domain-in-js

window.location.href == >>
"https://stackoverflow./questions/53249750/how-to-check-whether-url-only- 
 contains-the-domain-in-js"

You can check for pathName and do your thing:

if (window.location.pathname === "" || window.location.pathname === "/") {
   return true
}
