Answer 1

Yes, just do:

function test(txt){
   $scope.person[txt];
}

Answer 2

function test(txt){
  $scope.person[txt] = '';  // We need to assign something to it if not it wont work;
 }

Answer 3

Check Property accessors.

As any object you can access their properties using Dot notation or Bracket notation. When you don't know before hand what property you would be accessing you would use Bracket notation ideally.
