Javascript 找不到在angularJS中使用情态动词的简单示例

我离这很远吗

$scope.saveSuccess = function () {
    $('#saveSuccessModal').modal('show');
};

$scope.saveProgress = function () {
    var formattedDate = dateFormatFilter($scope.completedDate);
    //var formattedDate = $filter('date')($scope.completedDate, "yyyy-MM-dd")
    var step6 = {
        Id: $scope.stepId,
        ProblemId: $scope.problemId,
        WhenOptions: $scope.whenOptions,
        CounterMeasures: $scope.counterMeasures,
        CounterMeasureWhens: $scope.counterMeasureWhens,
        CompletedDate: formattedDate
        // step 6 specific data
    };

    $http.post(ROOT + '/step/SaveA3Step6/', step6)
        .success(function (result) {
            // log to console?
            $scope.saveSuccess();
        }).
        error(function (data, status, headers, config) {
            // log to console?
        });
};

因此，当保存成功时，我只希望弹出一个笑脸模式，表示数据已保存

<comment-modal id="saveSuccessModal" title="Progress Saved!"></comment-modal>

例如，我见过的最好的例子是诚实，非常清楚，谢谢
