207 Multi-Status: the response body is an XML document containing additional status information,Here’s a brief review of what the 2xx HTTP status codes mean (in addition to “Success”):,We’ve now created a JavaScript validation that will say the API check failed if the response HTTP status code is anything other than 200 or 201.,204 No Content: the server processed the request and returned no content

In the text box, enter:

var statusCode = context.response.meta.statusCode;

assert(statusCode == 200 || statusCode == 201,
   "Expected a 200 or 201 response");

Here's a simple example for a request that displays an alert, but only if a 404 status code is returned (lifted almost verbatim the link above):

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script>
   $(function() {
      var url = "some_url";
      $.ajax(url,
      {
         statusCode: {
         404: function() {
            alert('page not found');
         }
      }
   });   
});
</script>

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>. , The status read-only property of the Response interface contains the status code of the response (e.g., 200 for a success). , Note that at the top of the fetch() block we log the response status value to the console. ,Constructor Response()

var myStatus = response.status;
