如何在角度模态服务中将输入值传递给控制器

How to pass input value to controller in Angular Modal service

使用此角度模态服务：

app.service('modalService', ['$modal',
    function ($modal) {
        var modalDefaults = {
            backdrop: true,
            keyboard: true,
            modalFade: true,
            templateUrl: '/templates/modal.html'
        };
        var modalOptions = {
            closeButtonText: 'Close',
            actionButtonText: 'OK',
            headerText: 'Proceed?',
            bodyText: 'Perform this action?'
        };
        this.showModal = function (customModalDefaults, customModalOptions) {
            if (!customModalDefaults) customModalDefaults = {};
            customModalDefaults.backdrop = 'static';
            return this.show(customModalDefaults, customModalOptions);
        };
        this.show = function (customModalDefaults, customModalOptions) {
            //Create temp objects to work with since we're in a singleton service
            var tempModalDefaults = {};
            var tempModalOptions = {};
            //Map angular-ui modal custom defaults to modal defaults defined in service
            angular.extend(tempModalDefaults, modalDefaults, customModalDefaults);
            //Map modal.html $scope custom properties to defaults defined in service
            angular.extend(tempModalOptions, modalOptions, customModalOptions);
            if (!tempModalDefaults.controller) {
                tempModalDefaults.controller = function ($scope, $modalInstance) {
                    $scope.modalOptions = tempModalOptions;
                    $scope.modalOptions.ok = function (result) {
                        $modalInstance.close(result);
                    };
                    $scope.modalOptions.close = function () {
                        $modalInstance.dismiss('cancel');
                    };
                }
            }
            return $modal.open(tempModalDefaults).result;
        };
    }]);

我无法理解如何将值从模态(具有input(传递到控制器。

这是我的模态：

<input type="text" class="form-control" id="{{modalOptions.inputName}}" name="{{modalOptions.inputName}}" data-ng-model="modalOptions.inputVal" data-ng-if="modalOptions.inputName"  />
<button type="button" class="btn"
            data-ng-click="modalOptions.close()">{{modalOptions.closeButtonText}}</button>
<button class="btn btn-primary"
            data-ng-click="modalOptions.ok();">{{modalOptions.actionButtonText}}</button>

控制器：

$scope.addTopic = function () {
        var modalOptions = {
            closeButtonText: 'Cancel',
            actionButtonText: 'Create Topic',
            inputName: 'topicName'
        };
        modalService.showModal({}, modalOptions).then(function (result) {
            // I tried...
            var input = $scope.inputName; // and...
                input = result;
            $log.log("Adding topic '" + input + "' to publication no " + $scope.publication.id);
        });
    }

因此，输入是modalOptions中的一个选项，但是当用户输入值并单击"确定"时，不会向控制器发送任何内容。 $scope.inputName返回undefined，result也是如此。

理想情况下，我想得到一个像这样{ inputs : {name: 'inputName' , value: 'abcde'} }的对象。

在 Angular UI Bootstrap 中尝试 resolve 方法

var modalOptions = {
    resolve: {
        myvar: function () {
            return $scope.myvar;
        }
    }
};
modalService.showModal(modalOptions);
