XMLHttpRequest: statusText property

Available in workers

The read-only XMLHttpRequest.statusText property returns a string containing the response’s status message as returned by the HTTP server. Unlike XMLHttpRequest.status which indicates a numerical status code, this property contains the text of the response status, such as “OK” or “Not Found”. If the request’s readyState is in UNSENT or OPENED state, the value of statusText will be an empty string.

If the server response doesn’t explicitly specify a status text, statusText will assume the default value “OK”.

[!NOTE] Responses over an HTTP/2 connection will always have an empty string as status message as HTTP/2 does not support them.

Value

A string.

Examples

const xhr = new XMLHttpRequest();
console.log("0 UNSENT", xhr.statusText);

xhr.open("GET", "/server", true);
console.log("1 OPENED", xhr.statusText);

xhr.onprogress = () => {
  console.log("3 LOADING", xhr.statusText);
};

xhr.onload = () => {
  console.log("4 DONE", xhr.statusText);
};

xhr.send(null);

/**
 * Outputs the following:
 *
 * 0 UNSENT
 * 1 OPENED
 * 3 LOADING OK
 * 4 DONE OK
 */
