Glave HTTP odgovora v AJAX v JavaScript

Glave odgovora so shranjene v lastnosti headers objekta response. Pridobimo neko glavo:

public/client.jsbutton.addEventListener('click', function() {
  fetch('/ajax.html').then(response => {
    console.log(response.headers.get('Content-Type'));
  });
});

In zdaj ponovimo čez vse glave z zanko:

public/client.jsbutton.addEventListener('click', function() {
  fetch('/ajax.html').then(response => {
    for (let [key, value] of response.headers) {
      console.log(key, value);
    }
  });
});
