jQuery How to get the HTTP status code from within the ajax error method

Question

I m using jQuery to make an AJAX request  I want to perform different actions whether or not the HTTP status code is a 400 error or a 500 error  How can I achieve this       ajax        type   POST        url    controller action        data   form serialize         success  function data            alert  horray  200 status code                  error  function data              get the status code          if  code    400                 alert  400 status code  user error                        if  code    500                 alert  500 status code  server error                                 Update      GeorgeCummins mentioned that it  seemed odd  to work with the response body  This is the first time that I ve attempted doing this sort of thing  Is my approach not a best-practice  What would you recommend  I created another StackOverflow question for this here  What response status code should I send to an AJAX request when there is a user form validation error

If you re using jQuery 1 5  then statusCode will work   If you re using jQuery 1 4  try this   error  function jqXHR  textStatus  errorThrown        alert jqXHR status       alert textStatus       alert errorThrown       You should see the status code from the first alert

You should create a map of actions using the statusCode setting     ajax     statusCode        400  function           alert  400 status code  user error               500  function           alert  500 status code  server error                    Reference  Scroll to   statusCode    EDIT  In response to comments   If you need to take action based on the data returned in the response body  which seems odd to me   you will need to use error  instead of statusCode   error function  xhr  ajaxOptions  thrownError       switch  xhr status            case 404                  Take action  referencing xhr responseText as needed

An other solution is to use the response status function  This will give you the http status wich is returned by the ajax call   function checkHttpStatus url               ajax           type   GET           data              url  url          error  function response                alert url     returns a     response status              success                 alert url     Good link

use     statusCode        404  function           alert  page not found                -    ajax       type   POST       url    controller action       data   form serialize        success  function data           alert  horray  200 status code                statusCode        404  function           alert  page not found                400  function            alert  bad request
