Angularjs Angular.js从modal返回范围属性

在这个Angular.js指令中，我试图将

ng model=“commentBox”

返回到

modalInstance.result.then（function（result）{}

中的控制器，但我似乎没有从模式中使用

resolve

指令：

angular.module('main.vips').directive('deleteButton',
    function($modal) {
        var confirmModal = function(theScope) {
            return $modal.open({
                templateUrl: '../confirm_modal.html',
                scope: theScope,
                resolve: {
                    cBox: function() {
                        return theScope.commentBox;
                    }
                },
                backdrop: false
            });
        }

      return {
        templateUrl: 'vips/directives/delete_button.html',
        restrict: "AE",
        scope: {
          'iconAttribute': "@",
        },
        controller: function($scope, $element, $attrs) {
            var modalInstance;
            $scope.cancel = function(confirmModal) {
                modalInstance.dismiss();
            }
            $scope.ok = function(confirmModal) {
                modalInstance.close();
                modalInstance.result.then(function(result) {
                    console.log(result);
                }, function() {
                    console.log("dddddddddddddD");
                });
            }
            $element.on("click", function(event) {
                modalInstance = confirmModal($scope);
            });
        }
     }
});

您可能希望这样构造代码：或者这样：

是的……需要按引用传递，而不是按值传递。
