indicates success, but the textual part of the response line indicates the URI by which the newly created document should be known. Accepted 202 The request has been accepted for processing, but the processing has not been completed. The request may or may not eventually be acted upon, as it may be disallowed when processing actually takes place. jquery no cache ajax there is no facility for status returns from asynchronous operations such as this. Partial Information 203 When received in the response to a GET command, this indicates that the returned metainformation is not a definitive set of the object from a server with a copy of the object, but is from a private overlaid web. This may include annotation information about the object, for example. No Response 204 Server has received the request but there is no information to send back, and the client should stay in the same document view. This is mainly to allow input for scripts without changing the document at the same time. Error 4xx, 5xx The 4xx codes are intended for cases in which the client seems to have erred, and the 5xx codes for the cases in which the server is aware that the server has erred. It is impossible to distinguish these cases in general, so the difference is only informational. The body section may contain a document describing the error in human readable form.

They only talk about "error". I suspect this is either an anachronism, or someone was confused as to what the antonym of "success" was in this case. http://api.jquery.com/jQuery.ajax/ share|improve this answer answered Sep 14 '11 at 14:28 Gian 10.9k3043 From the docs: Deprecation Notice: The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callbacks are deprecated as of jQuery 1.8. To prepare your code for their eventual removal, use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead. –DMTintner Oct 7 '13 at 13:40 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

It's silent and doesn't warn the user about anything. 205 Reset Content This allows the server to reset any content returned by a CGI. 206 Partial Content The requested file wasn't downloaded entirely. This is returned when the user presses the stop button before a page is loaded, for example. 3xx RedirectionThe client must take additional action to complete the request. top Code Status Explanation 300 Multiple Choices The requested address refers to more than one file. Depending on how the server is configured, you get an error or a choice of which page you want. 301 Moved Permanently If the server is set up properly it will automatically redirect the reader to the new location of the file. 302 Moved Temporarily Page has been moved

Codes With Each API Response By Ben Nadel on February 24, 2010 Tags: ColdFusion, Javascript / DHTML For a long time, I have thought about API request failures as falling into just two distinct categories: failure to communicate (ie. the server was down) or bad data (ie. invalid parameters). Failures to communicate with the server were out of my hands; as such, there was nothing I could do with those from a server standpoint. Requests with bad data, on the other hand, were certainly something within my domain of control and, happened to be something that I had strong feelings about.Much of what I believe about API responses comes from my experience with SOAP-based web services. If you look at the SOAP request / response life cycle, you'll notice that SOAP responses always return a 200 status code, even when the request is invalid. Granted, the response might contain a SOAP fault (error) structure; but, from an HTTP standpoint, the request was successful.I took this SOAP approach and extended it to my non-SOAP APIs. Typically, in my API architecture, the responses returned from the server always contain a 200 status code. Even if the request happens to be invalid, any error information would be contained in the body of a 200 response. This has been working well for me; but a few months ago, in a post about handling AJAX errors with jQuery, Simon Gaeremynck suggested that I use more appropriate status codes to describe the API response.When using a variety of status codes in jQuery, only 200 responses will be handled by the success callback function; all other responses - 400, 404, 500, etc. - will be handled by the error callback function. I have to say, there is definitely something very delicious about having the success callback function handle only successful requests; I think it would keep the success work flow much cleaner. Definitely, this is something worth exploring; and, while it may have taken me a few months to get around to it, I think I like what I am seeing.To test this, I set up a simple ColdFusion API page. For demo purposes, the API will do nothing but return a Girl object with an ID of 4. If the ID is not passed in, I will return a Bad Request response (status code 400). If the ID is passed in, but is not 4, I'll return a Not Found response (status code 404). And, if there is an unexpected error, I'll return an Internal Server Error (status code 500).api.cfm
