Question

我刚开始学习AngularJS。我正在尝试使用AspNet Boilerplate MVC / AngularJS模板创建一个简单的项目。我可以在网络中看到我的GetAll XHR结果在我请求的查询中成功true，但Chrome元素中的div为空（它们具有元素之后/之前）。

Index.js

(function () {
    angular.module('app').controller('app.views.events.index', [
        '$scope', '$uibModal', 'abp.services.app.event',
        function ($scope, $uibModal, eventService) {
            var vm = this;

            vm.events = [];
            vm.filters = {
                includeCanceledEvents: false
            };

            function getEvents() {
                eventService.getAll(vm.filters).then(function (result) {
                    vm.events = result.items;
                });
            }

            getEvents();
        }
    ]);
})();

Index.cshtml

<div class="row clearfix" ng-controller="app.views.events.index as vm">
    <div class="col-lg-12 col-md-12 col-sm-12 col-xs-12">
        <div class="card main-content">
            <div class="body table-responsive">
                <table class="table table-hover table-striped">
                    <thead>
                        <tr>
                            <th>@L("Title")</th>
                            <th>@L("Description")</th>

                        </tr>
                    </thead>
                    <tbody>
                        <tr ng-repeat="event in vm.events">
                            <td>{{event.title}}</td>
                            <td>{{event.description | characters:100}}</td>
                        </tr>
                    </tbody>
                </table>
            </div>
        </div>
    </div>
</div>

            .WhereIf(!input.IncludeCanceledEvents, e => !e.IsCancelled)

        var registration = await _eventManager.RegisterAsync(@event, user);
        await CurrentUnitOfWork.SaveChangesAsync();
        return registration;
    }
}

任何帮助都很感激。

Answer 1

响应对象result不包含data。您必须使用result.items代替result.data.items。

function getEvents() {
    eventService.getAll(vm.filters).then(function (success) {
        vm.events = result.items;
    },function (error){

   });
}

Answer 2

您可以使用以下代码更改getEvents（）。此处Response对象结果包含data。您必须使用result.data.items代替result.items。

        function getEvents() {
            eventService.getAll(vm.filters)
                .then(function (result) {
                    vm.events = result.data.items;
                });
        }
