Response.statusText

The statusText read-only property of the Response interface contains the status message corresponding to the HTTP status code in Response.status.

For example, this would be OK for a status code 200, Continue for 100, Not Found for 404.

A String containing the HTTP status message associated with the response. The default value is "".

See HTTP response status codes for a list of codes and their associated status messages. Note that HTTP/2 does not support status messages.

In our Fetch Response example (see Fetch Response live) we create a new Request object using the Request() constructor, passing it a JPG path. We then fetch this request using fetch(), extract a blob from the response using Response.blob, create an object URL out of it using URL.createObjectURL, and display this in an <img>.

Note that at the top of the fetch() block we log the response statusText value to the console.

var myImage = document.querySelector('img');

var myRequest = new Request('flowers.jpg');

fetch(myRequest).then(function(response) {
  console.log(response.statusText); // returns "OK" if the response returned successfully
  response.blob().then(function(myBlob) {
    var objectURL = URL.createObjectURL(myBlob);
    myImage.src = objectURL;
  });
});
