Can I a POST below code to any othes domain?

Question

Is it possible to make an HTTP POST request from JavaScript to any domain name?

Javascript

var xhr = new XMLHttpRequest();

xhr.open("POST", 'URL linki', true);

 //Send the proper header information along with the request

 xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xhr.onreadystatechange = function() { // Call a function when the state changes.

if (this.readyState === XMLHttpRequest.DONE && this.status === 200) {

    // Request finished. Do processing here.

 }
 }
 xhr.send("foo=bar&lorem=ipsum");

 // xhr.send(new Int8Array());

 // xhr.send(document);

and I would like print on the screen. Is it possible?

Yes, it's possible to make a request to any domain as long as the domain in question accepts the request, and the server allows CORS (Cross-Origin Resource Sharing). The latter is only required if you want a response, as you're sharing resources across origins.
