This is the closest I've found to returning a variable reference for the logged-on user.

• Try it out it's simple to test:

1. In IE browse to your SharePoint site, open developer tools press (f12)
2. Open the Console press (ctl + 2)
3. Switch line-mode (with your cursor in the "Console input" press (ctl + alt + m)
4. Paste all the following contents into the console then press (ctl + enter)

function iWannaDoSomethingWith(thisUser){ if(thisUser === null){ alert('failed to get user'); } else{ alert('User name:' + thisUser.get_title() + '\n Login Name:' + thisUser.get_loginName()); } } function necessaryEvilToWireItAllTogether(nameOfFuncWeReallyWantToCall){ if (typeof(nameOfFuncWeReallyWantToCall)==="function") { var ctx = new SP.ClientContext.get_current(); var oWeb = ctx.get_web(); var currentUser = oWeb.get_currentUser(); currentUser.retrieve(); ctx.load(oWeb); ctx.executeQueryAsync( function(){ // successful Async call nameOfFuncWeReallyWantToCall(currentUser); }, function(){ // failed Async call nameOfFuncWeReallyWantToCall(null); } ); } } ExecuteOrDelayUntilScriptLoaded(function(){necessaryEvilToWireItAllTogether(iWannaDoSomethingWith);}, "sp.js");
