Should I use done and fail for new jQuery AJAX code instead of success and error

Question

I have coded like this     ajax   cache  false      url    Admin Contents GetData       data    accountID  AccountID        success  function  data                CityID   html data              error  function  ajaxContext            alert ajaxContext responseText              But when I look at the jQuery  ajax   documentation at the end it seems to suggest I should be coding like this below or at least it suggests adding a  done   and a  fail     var request     ajax   cache  false      url    Admin Contents GetData       data    accountID  AccountID        request done function  data        xxx      request fail function  jqXHR  textStatus        xxx        Update  If I code like this is it the same or is there some advantage to breaking it into three      ajax   cache  false      url    Admin Contents GetData       data    accountID  AccountID      done function  data        xxx     fail function  jqXHR  textStatus        xxx

When we are going to migrate JQuery from 1 x to 2x or 3 x in our old existing application   then we will use  done  fail instead of success error as JQuery up gradation is going to be deprecated these methods For example when we make a call to server web methods then server returns promise objects to the calling methods Ajax methods  and this promise objects contains  done  fail  etc methods Hence we will the same for success and failure response  Below is the example it is for POST request same way we can construct for request type like GET         ajax               type   POST               url  url              data     name    sheo                 contentType   application json  charset utf-8               async  false              cache  false                done function  Response                        do something when get response                           fail function  Response                          do something when any error occurs

As stated by user2246674  using success and error as parameter of the ajax function is valid  To be consistent with precedent answer  reading the doc    Deprecation Notice  The jqXHR success    jqXHR error    and jqXHR complete   callbacks will be deprecated in jQuery 1 8  To prepare your code for their eventual removal  use jqXHR done    jqXHR fail    and jqXHR always   instead   If you are using the callback-manipulation function  using method-chaining for example   use  done     fail   and  always   instead of success    error   and complete

I want to add something on  Michael Laffargue s post   jqXHR done   is faster   jqXHR success   have some load time in callback and sometimes can overkill script  I find that on hard way before   UPDATE   Using jqXHR done    jqXHR fail   and jqXHR always   you can better manipulate with ajax request  Generaly you can define ajax in some variable or object and use that variable or object in any part of your code and get data faster  Good example      Initialize some your AJAX function    function call ajax attr       var settings   extend           call               users           option             list         attr         return   ajax           type   POST           url     exapmple com  ajax php           data  settings          cache   false                    Somewhere in your code           call ajax                     id   10      option    edit user      change               name    John Doe                         done function data           DO SOMETHING AWESOME
