Get username for SAPUI5 in WebIDE

Question

This is probably just some easy JavaScript code i can't figure out, but i am trying to get the username of currently logged in user. Or this is an oData concept, which i am not familiar with. Here is the code for retrieving it:

onComment: function (oEvent) 
    {
        //gets username
        var userModel = new sap.ui.model.json.JSONModel("/services/userapi/currentUser");
        var username = userModel;
     console.log(username);
    }

I know something is supposed to go after the var username = userModel but i cannot get the correct output. Here is what i am getting in the console

constructor {pSequentialImportCompleted: Promise, mEventRegistry: Object, mMessages: null, id: "id-1501515372158-22", oData: Object…}

oData: Object

+displayName:"Tyler Genio (Sxxxxxxxx)"

+email:"tyler.i.Genio@company.com"

+firstName:"Tyler"

+lastName:"Genio"

+name: "Sxxxxxxxx"

How do i get the first and last name out of that? I've see a few articles online that talk about it, but some of it goes over my head. Sorry for any confusion about the coding format on here.

Answer 1

if your model is structured as stated, ie

{
    "displayName": "Tyler Genio (Sxxxxxxxx)",
    "email": "tyler.i.Genio@company.com",
    "firstName": "Tyler",
    "lastName": "Genio",
    "name": "Sxxxxxxxx"
}

then userModel.getProperty("/name");
