如何在Angular JS谷歌地圖中使用地理定位？

Question

我在項目中使用Angular Google Maps。我沒有在tutoria中找到信息;如何使用地理位置和檢測當前用戶的位置。我如何做到這一點？

我想：

$scope.getGeoLocation = function(){ 
       if (navigator.geolocation) { 
        navigator.geolocation.getCurrentPosition($scope.showPosition); 
       } else { 
        console.log("Geolocation is not supported by this browser."); 
       } 
      } 

      $scope.showPosition = function (position) { 
       $scope.map.bounds = { 
        northeast : position.coords.latitude, 
        southwest: position.coords.longitude 
       } 

       $scope.map.center = {latitude: position.coords.latitude, longitude: position.coords.longitude} 
       console.log(position.coords.longitude); 
      } 

，但我得到的錯誤：

Invalid map bounds for new value: {"northeast":40.409261699999995,"southwest":49.8670924}

入住條件，來源：
if !newValue?.northeast?.latitude? or !newValue?.northeast?.longitude? or !newValue?.southwest?.latitude? or !newValue?.southwest?.longitude? $log.error "Invalid map bounds for new value: #{JSON.stringify newValue}"
