全局變量的角度局部變量

Question

我想從JSON範圍外的JSON獲取國家名稱，但不知怎的，它似乎不通過，我做錯了什麼？我看着$ rootScope，但似乎並沒有太多。原則上很簡單，我想在其他範圍或頁面本身中使用國家/地區名稱作爲變量，也想在Controller.cs（.net）中使用它將其發送到數據庫

app.controller('PageController', 
    function ($scope, $http) { 

var analyticsCountry = "default"; 

$.getJSON('//www.geoplugin.net/json.gp?jsoncallback=?', 

function (data) { 
    $scope.testing = data; 
    $scope.testing.country = data.geoplugin_countryName; 
    //console.log($scope.testing.country); 
    analyticsCountry = $scope.testing.country; 
}); 

    console.log(analyticsCountry); 

    $scope.GetTrendingCDsByCountry = function() { 
     $http({ 
      method: 'Get', 
      url: "/CD/GetTrending?id=" + analyticsCountry 

     }) 
      .success(function (data, status, headers, config) { 
       $scope.cds= data; 
      }) 
      .error(function (data, status, headers, config) { 
       $scope.message = 'Unexpected Error'; 
      }); 

    }; 


});

如果你想在視圖中。只要將它綁定到$scope，你就可以走了。並且@Suren Srapyan表示回調將在保存價值"default"的console.log()之後執行。

app.controller('PageController', 
    function ($scope, $http) { 

$scope.analyticsCountry = "default"; 
$scope.GetTrendingCDsByCountry = function() { 
    $http({ 
     method: 'Get', 
     url: "/CD/GetTrending?id=" + $scope.analyticsCountry 

    }) 
     .success(function (data, status, headers, config) { 
      $scope.cds= data; 
     }) 
     .error(function (data, status, headers, config) { 
      $scope.message = 'Unexpected Error'; 
     }); 

}; 

$.getJSON('//www.geoplugin.net/json.gp?jsoncallback=?', 

function (data) { 
    $scope.testing = data; 
    $scope.testing.country = data.geoplugin_countryName; 
    //console.log($scope.testing.country); 
    $scope.analyticsCountry = $scope.testing.country; 
    console.log($scope.analyticsCountry); 
    $scope.GetTrendingCDsByCountry(); 
    }); 

}); 

現在，它會工作，並且很容易在視圖中訪問。
