I am using _spPageContextInfo object to get currently logged in username in SharePoint 2013.In this process first i will get userId value and then i will make an ajax call with this userId value and i will get current user values. Its working fine. Till now i am getting userLoginName and EMail values. Now i need to find out user alias. Unfortunately the _spPageContextInfo object does contain any user alias property.So please help me in this scenario.
BTW i know that there is jQuery plugin called SPServices to find user values but even this is not much helpful to me as it also does not contain any information about user alias.
