What are the possible values for `jqXHR.status`?

Question

What are the possible values for jqXHR.status?

So far, I can see the following:

if (jqXHR.status === 0) { msg = 'Network Problem'; }
else if (jqXHR.status == 404) { msg = 'Requested page not found. [404]'; }
else if (jqXHR.status == 500) { msg = 'Internal Server Error [500].'; }

Solution 1

It can be anything found here.

http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html

The status value is the HTTP protocol status field that http servers send on the response.

Note at this point, the jquery ajax documentation indicates that status is deprecated, and you should use statusCode instead.

Solution 2

According to the jQuery API Documentation:

For backward compatibility with XMLHttpRequest, a jqXHR object will expose the following properties and methods:

(...)

• status
• statusText

You can then read more about the XMLHttpRequest object on its WHATWG Living Standard page or on its page at at MDN or at W3Schools. The latter also provides a link to a list of HTTP Status Messages.

Note that jqXHR also exposes XMLHttpRequest's statusText attribute which can be used to get a quick and useful error message in addition to the status code.

It doesn't say anywhere that status is deprecated

In fact statusCode is a methid to pass callbacks to for each type of error you want to handle
