You could try something like this  copied from the jQuery Ajax examples   var request     ajax      url   script php      type   POST      data   id   menuId      dataType   html       request done function msg       console log  msg         request fail function jqXHR  textStatus       console log   Request failed      textStatus          The problem with your original code is that the error argument you pass into your on function isn t actually coming from anywhere  JQuery on doesn t return a second argument  and even if it did  it would relate to the click event not the Ajax call

Ajax call error handler will be triggered if the call itself fails   You are probably trying to get the error from server in case login credentials do not go through  In that case  you need to inspect the server response json object and display appropriate message   e preventDefault      ajax        type   POST       url  requestURI      data    formLogin  serialize        dataType   json       success  function result           if result hasError    true                        if result error code     AUTH FAILURE                                   wrong password                 console log  Recieved authentication error                        login errors auth   fadeIn                              else                                 generic error here                     login errors unknown   fadeIn                                        Here   result  is the json object returned form the server which could have a structure like    return   array           hasError    gt    validPassword           error code    gt   AUTH FAILURE     die jsonEncode  return
