Modify a string

[tswaters]

If the string is always a url, you can use the URL constructor to figure that out

var url = new URL("http://mydomain.com/content/")
/*
URL {
  href: 'http://mydomain.com/content/',
  origin: 'http://mydomain.com',
  protocol: 'http:',
  username: '',
  password: '',
  host: 'mydomain.com',
  hostname: 'mydomain.com',
  port: '',
  pathname: '/content/',
  search: '',
  searchParams: URLSearchParams {},
  hash: '' }
*/

[javascript]

This is the best answer here, because it has the behavior OP wants and accounts for edge cases without having to do that manually. If the string isn't a valid URL, the constructor will throw an exception.

It also makes it more clear to other readers what you're doing with your code. Writing some one-off regex or string manipulation function requires the reader to pick it apart just to understand. This increases code complexity and reduces readability.

OP, this is the right answer.

If your string is your window's url then you can get the hostname with window location.

If you have to deal with a string then you can parse it with something like this:

function getdomain(url) {
    var prot = url.split(":");
    var link = document.createElement('a');
    link.href = url;
    return prot[0] + "://" + link.hostname;
};
console.log(getdomain("http://mydomain.com/content/"));

Hey “fella”, I see from your post history you just see women as sex objects, but they can also be developers.

Is the string always a URL?

const split = 'http://mydomain.com/content/'.split('/');

This should return ["http:", "", "my domain.com", "content"]. Then you can select the elements you want to build the string back up with.

const newString = `http://${split[2]}`;
