I need to access a variable from a .getCurrentPosition() function [требует правки]

Here is the code and i want for example to access the latitudw variable outside of this function and for example set to its value.

<script>
  var latitude = "b";
  var longitude = "c";
  navigator.geolocation.getCurrentPosition(function showLocation(position) {
    latitude = position.coords.latitude;
    longitude = position.coords.longitude; 
  });
  navigator.geolocation.getCurrentPosition(showLocation(position);
  $(".test").html(latitude)
</script>
