javascript - 注入(inject)工厂时 Angular 停止工作

Question

我下定决心要将服务和工厂注入(inject)其中。当我注入(inject)一个名为 ValidationMatrixFactory 的工厂时，它不再起作用了。主页加载但链接不再解析，基本上点击任何内容都没有效果。 Angular 不会抛出任何错误。一切都停止工作。我试过多个浏览器，重启 IIS，都没有效果。

解析中的 console.log 语句永远不会被命中。这是解决方案:

        resolve: {
            eventData: ['$http', '$stateParams', 'ViewMatrixService', 'ValidationMatrixFactory', function ($http, $stateParams, ViewMatrixService, ValidationMatrixFactory) {
                console.log('EventId: ' + $stateParams.eventId);
                return $http.get('http://localhost:10569/api/eventView/' + $stateParams.eventId).then(function (response) {
                    ViewMatrixService.GenerateViewMatrix(response.data);
                    ValidationMatrixFactory.GenerateValidationMatrix(response.data);
                    return response.data;
                });
            }]
        }

如果我删除对 ValidationMatrixFactory 的引用，一切都会正常。 ValidationMatrixFactory 与 ViewMatrixService 非常相似，所以我不确定为什么现在会出现问题。

这是 ValidationMatrixFactory:

angular.module('myWebApp.services')
    .factory('ValidationMatrixFactory', function() {
        var ValidationMatrixFactory = {};

        ValidationMatrixFactory.GenerateValidationMatrix = function (eventData) {
            var currentStage = eventData.CoreEvent.Stage;
            initializeValidationMatrix();
            determineRequiredFields(currentStage);
        }

        function initializeValidationMatrix() {
            ValidationMatrixFactory.EventTitleRequired = false;
            ValidationMatrixFactory.EventSummaryRequired = false;
            ValidationMatrixFactory.DesiredPublicationDateRequired = false;
            ValidationMatrixFactory.DesiredEffectiveDateRequired = false;
            ValidationMatrixFactory.ReasonForDesiredEffectiveDateRequired = false;
            ValidationMatrixFactory.AssessmentTargetDateRequired = false;
            ValidationMatrixFactory.FRSOTargetDateRequired = false;
            ValidationMatrixFactory.BLRTargetDateRequired = false;
            ValidationMatrixFactory.SSOTargetDateRequired = false;
            ValidationMatrixFactory.BLSOTargetDateRequired = false;
            ValidationMatrixFactory.FSOTargetDateRequired = false;
            ValidationMatrixFactory.PublicationTargetDateRequired = false;
            ValidationMatrixFactory.EffectiveTargetDateRequired = false;
            ValidationMatrixFactory.RMRequired = false;
            ValidationMatrixFactory.PublisherRequired = false;
            ValidationMatrixFactory.MoPRequired = false;
            ValidationMatrixFactory.PriorityRequired = false;
        }

        function determineRequiredFields(currentStage) {
            ValidationMatrixFactory.EventTitleRequired = true;
            ValidationMatrixFactory.EventSummaryRequired = true;
            ValidationMatrixFactory.ReasonForDesiredEffectiveDateRequired = true;
            ValidationMatrixFactory.DesiredPublicationDateRequired = true;
            ValidationMatrixFactory.DesiredEffectiveDateRequired = true;

            if (currentStage.StageNumber > 1) {
                ValidationMatrixFactory.AssessmentTargetDateRequired = true;
                ValidationMatrixFactory.FRSOTargetDateRequired = true;
                ValidationMatrixFactory.BLRTargetDateRequired = true;
                ValidationMatrixFactory.SSOTargetDateRequired = true;
                ValidationMatrixFactory.BLSOTargetDateRequired = true;
                ValidationMatrixFactory.FSOTargetDateRequired = true;
                ValidationMatrixFactory.PublicationTargetDateRequired = true;
                ValidationMatrixFactory.EffectiveTargetDateRequired = true;
                ValidationMatrixFactory.RMRequired = true;
                ValidationMatrixFactory.PublisherRequired = true;
                ValidationMatrixFactory.MoPRequired = true;
            }

            if (currentStage.StageNumber > 2) {
                ValidationMatrixFactory.PriorityRequired = true;
            }
        }

        ValidationMatrixFactory.ValidateFields = function (saveType) {

        }
    });

我在 index.html 中引用了脚本。

    <script src="libraries/angular/1.4.8/angular.min.js"></script>
    <script src="libraries/angular/1.4.8/angular-animate.min.js"></script>

Answer 1

您必须从工厂返回ValidationMatrixFactory对象。

.factory 是我们一般调用的方法，以名称和函数作为参数。这个函数只是一个必须返回对象的函数。如果您不返回任何内容，angular 将陷入无限摘要。

如果您使用了 .service，则不返回任何内容都可以。那是因为服务是一个构造函数。您可以在服务函数中包含 this 并向 this 添加属性。

更新

貌似在angularjs 1.3.4版本之前，没有报错。从1.3.4开始，无限摘要抛出错误。
