$scope.model 属性的配置未定义

Question

我正在为 Umbraco 7 中的内容选择器实现一个控制器，我需要在其中更改起始节点以匹配特定的内容节点。然而，当我使用内容选择器加载页面时，我收到一条错误消息：

"Cannot read property 'config' of undefined"

关于这段代码：

$scope.model.config.StartNodeId = 1083;
     if ($scope.model.config.StartNodeId) {
          options.startNodeId = $scope.model.config.StartNodeId;
     }

我的整个控制器：

angular.module("umbraco").controller("UIOMatic.FieldEditors.Pickers.ContentController",
    function ($scope, $routeParams, $http, dialogService, entityResource, iconHelper) {

        function init() {
            if (!$scope.setting) {
                $scope.setting = {};
            }

            var val = parseInt($scope.property.value);

            if (!isNaN(val) && angular.isNumber(val) && val > 0) {
                $scope.showQuery = false;

                entityResource.getById(val, "Document").then(function (item) {
                    item.icon = iconHelper.convertFromLegacyIcon(item.icon);
                    $scope.node = item;
                });
            }

            $scope.openContentPicker = function () {
                var d = dialogService.treePicker({

                    section: "content",
                    treeAlias: "content",
                    multiPicker: false,
                    callback: populate
                });
            };

            $scope.model.config.StartNodeId = 1083;
            if ($scope.model.config.StartNodeId) {
                options.startNodeId = $scope.model.config.StartNodeId;
            }

            $scope.clear = function () {
                $scope.id = undefined;
                $scope.node = undefined;
                $scope.property.value = undefined;
            };

            function populate(item) {
                $scope.clear();
                item.icon = iconHelper.convertFromLegacyIcon(item.icon);
                $scope.node = item;
                $scope.id = item.id;
                $scope.property.value = item.id;
            }
        };

        if ($scope.valuesLoaded) {
            init();
        } else {
            var unsubscribe = $scope.$on('valuesLoaded', function () {
                init();
                unsubscribe();
            });
        }
    });

我尝试将起始节点 ID 更改为 1083，这是我想要的，我可以很好地打开内容选择器，但它不允许我保存我的更改。它还允许多重拾取，我在我的配置对象中将其设置为 false。

我认为你应该在给它的对象赋值之前初始化 $scope.model。使用

$scope.model = {}
