angularjs代码refine，还是老一套

有段定时刷新的代码是这么写的：

       var is_getting = false;        var refresh_interval = 2000;        var get_encoder_channels = function() {            if (is_getting) {                return;            }            if ($scope.last_refresh_time) {                $scope.left_time = (refresh_interval + $scope.last_refresh_time - +new Date())/1000;                if ($scope.left_time >= 0) {                    return;                }                $scope.left_time = 0;            }            is_getting = true;            Encoder_integrated_service.summary(function(data) {                is_getting = false;                $scope.last_refresh_time = +new Date();                $scope.summary = data;            });        };        var stop;        $scope.refresh = function() {            if(angular.isDefined(stop)) return;            stop = $interval(get_encoder_channels, 100);            get_encoder_channels();        };        $scope.stop_refresh = function() {            if (angular.isDefined(stop)) {                $interval.cancel(stop);                stop = undefined;            }        };        $scope.$on('$destroy', function() {            // Make sure that the interval is destroyed too            $scope.stop_refresh();        });        $scope.refresh();

改成这样就好：

        async_refresh2.refresh_change(function(){            Encoder_integrated_service.summary(function(data) {                $scope.summary = data;                async_refresh2.request();            }, function(){                async_refresh2.request();            });        }, 2000);        async_refresh2.request(0);
