javascript - 优化 Angular 重复代码

Question

如何优化这里的重复代码

angular.module('myApp')
    .controller('LogsController', function ($scope, LogsService) {
        $scope.updatingLogs = true;
        $scope.loggers = {};

        LogsService.findAll().$promise.then(function(data) {
            $scope.loggers = data;
            $scope.updatingLogs = false;
        });

        $scope.changeLevel = function (name, level) {
            LogsService.changeLevel({name: name, level: level}, function () {
                $scope.updatingLogs = true;
                LogsService.findAll().$promise.then(function(data) {
                    $scope.loggers = data;
                    $scope.updatingLogs = false;
                });
            });
        };
    });

这里有一个建议:

angular.module('myApp')
    .controller('LogsController', function ($scope, LogsService) {
        $scope.updatingLogs;
        $scope.loggers = LogsService.findAll();

        $scope.changeLevel = function (name, level) {
            $scope.updatingLogs = LogsService.changeLevel({name: name, level: level}, function () {
                LogsService.findAll().$promise.then(function(data) {
                    $scope.loggers = data;
                    $scope.updatingLogs = null;
                });
            });
        };
    });
