角度UI引导uibModalInstance。结果未产生任何值

以下几点需要考虑:

1. 首先,你不需要使用 controllerAs 当您定义模态时,在ui引导程序中,您应该只使用 controller: myModalController as vm (或者在你的例子中是ctrl)。

2. 然而,在您的指令中,您定义 controllerAs: 'ctrl', 但你以后会用 vm .

3. 在模态控制器中,您只使用 $uibModalInstance.dismiss() 方法,disdiss方法关闭模态并激活promise拒绝处理程序 uibModalInstance.result 许诺 你应该使用 $uibModalInstance.close() 以激活解析处理程序。否则所有这些代码都无法运行。

我会这样写的

   spinner.spinnerShow();

   $uibModal.open({
       animation: true,
       templateUrl: 'app/components/capture/cabinet.pop-up.html',
       controller: ModalCtrl as ctrl,
       size: 'lg',
       resolve: {
           thumbnailData: function () {
               return ctrl.thumbnail;
           }
       }
   }).result
        .then(function (thumbnailData) {
            //call the service to get the comments
            return cabinetService.getComments(thumbnailData);   
        }, function() {
             $log.info('Modal dismissed at: ' + new Date());
        }).then(function (data) {
            // we get to this 'then' after cabinetService.getComments finished
            $scope.comments = data;
        }).catch(function (err) {
            $log.err('Unable to open the screen shot, Please try later !', {ttl: 20000});
        }).finally(spinner.spinnerHide);
    }

并添加

ctrl.ok = function() {
    $uibModalInstance.close(valueForResolveHandler);
};

到ModalCtrl

事实上,我将服务调用转移到了引用控制器,它得到了解决并起了作用。

(function () {
'use strict';

angular
    .module('myModule')
    .directive('cabinet', function () {
        return {
            restrict: 'E',
            replace: true,
            controller: CabinetThumbnails,
            controllerAs: 'ctrl',
            bindToController: true,
            link: link,
            templateUrl: 'app/components/capture/cabinet.directive.html',
            scope: {
                thumbnail: '='
            }
        };
    });
function link(scope, el, attrs) {
}

CabinetThumbnails.$inject = ['$scope','$uibModal'];

function CabinetThumbnails($scope,$uibModal) {
    var vm = this;

    vm.showImage = showImage;

    activate();

    function activate() {
    }

    function showImage() {
        var uibModalInstance = $uibModal.open({
            animation: true,
            templateUrl: 'app/components/capture/cabinet.pop-up.html',
            controller: ModalCtrl,
            controllerAs: 'ctrl',
            size: 'lg',
            resolve: {
                thumbnailData: function () {
                    return vm.thumbnail;
                }
            }
        });
    }
}

ModalCtrl.$inject = ['$scope', '$uibModalInstance', 'thumbnailData', 'growl','cabinetService'];

function ModalCtrl($scope, $uibModalInstance, thumbnailData, growl,cabinetService) {
    var ctrl = this;

    ctrl.thumbnailData = thumbnailData;
    ctrl.save = save;
    ctrl.cancel = cancel;

    //call this method to get executed while the directive loads to open the pop-up
    getComments();

    function getComments()
    {
        cabinetService
            .getComments(thumbnailData)
            .then(function (data) {
                ctrl.comments = data;
            })
            .catch(function (err) {
                growl.err('Unable to get comments, Please try later !', {ttl: 20000});
            })
    }

    function save() {
    var form = $scope.cabinetForm;

        if (!form.$invalid && form.$dirty && form.$valid) {
            var data = {
                CabinetFileID: ctrl.thumbnailData.CabinetFileID,
                Comment: ctrl.inputcomment
            };
            //call the service
            cabinetService
                .addComments(data)
                .then(function (data) {
                  //refresh the comments by calling the getComments method again
                    ctrl.thumbnailData.CommentCount = ctrl.thumbnailData.CommentCount + 1;
                    getComments();
                    ctrl.inputcomment = '';
                })
                .catch(function (err) {
                    growl.err('Unable to add comment, please try later !', {ttl: 20000});
                })
        } else {
            growl.info('Please enter the comment');
        }
    }

    function cancel() {
        $uibModalInstance.dismiss();
    }
}
}());
