Hot取消在angularjs模式窗口的開放

Question

在我的角度應用程序，我有一個網格，我有一個按鈕來顯示有關當前行的詳細信息。我通過$ http獲取詳細的數據到一個sql數據庫，當數據正確提取時，我打開一個模式窗口來顯示細節。我想要的是如果出現錯誤（例如，http狀態碼NOT FOUND），防止打開模式窗口。我的代碼如下：

var modalInstance = $modal.open({ 
    templateUrl: '/Scripts/app/views/konto/kontoCrud.htm', 
    backdrop: true, 
    keyboard: true, 
    windowClass: 'szpModal fade in', 
    controller: 'KontoCrudCtrl', 
    resolve: { 
     konto: function() { 
      if ($scope.mode === "new") { 
       return { mode: mode, 
        sifra: "", 
        naziv: "" 
       }; 
      } else { 
       //console.log($scope.selectedItem); 
       var result = kontoFactory.getKonto($scope.selectedItem[0].id); 
       console.log(result); 
       if (result.status === "OK") { 
        return result; 
       } else { 
        toastr.error("Error fetching data!"); 
        **// HERE I WANT TO CANCEL THE OPENING OF THE WINDOW AS 
        // THE RECORD WAS NOT FOUND** 
       } 

      } 
     } 
    }
