How to find out the permissions issued by the user (for geolocation)?

Question

JavaScript

I need to get the position of the user (navigator.geolocation.getCurrentPosition)
But first I need to get the permission. Can you tell me how can I know that I have received this permission?

Answer 1

navigator.geolocation.getCurrentPosition(
  function(){
    // Дали добро, делаем все что нужно
  }, 
  function(){
    // Ошибка. В т.ч. если отказали в определении местоположения.
  }
)
