The read-only XMLHttpRequest.status
property returns the numerical HTTP status code of the XMLHttpRequest
's response.
Before the request completes, the value of status
is 0. Browsers also report a status of 0 in case of XMLHttpRequest
errors.
const xhr = new XMLHttpRequest();
console.log("UNSENT: ", xhr.status);
xhr.open("GET", "/server");
console.log("OPENED: ", xhr.status);
xhr.onprogress = () => {
console.log("LOADING: ", xhr.status);
};
xhr.onload = () => {
console.log("DONE: ", xhr.status);
};
xhr.send();
