我正在尝试获取网格的选定行并将其分配给变量。在Kendo的演示中，选定的行将输出到控制台：

我已经将'row'定义为var row；在控制器内（第一行位于页面顶部：
change: function (e) {
row = this.selectedKeyNames();
`enter code here` },
但是当我尝试发布数据时，我得到的行是“未定义”消息。
var app = angular.module('collection-app', ['kendo.directives'])
.controller('CollectionController', ['$scope', '$http', "$window", function ($scope, $http, $window) {
var self = this;
var dataUrl = UrlParams.type != null ? UrlParams.Collection + "?type=" + UrlParams.type : UrlParams.Collection;
var viewUrl = UrlParams.view != null ? UrlParams.Collection + "/Views/" + UrlParams.view : UrlParams.Collection + "/Views/Default";
var row;
是因为无法在gridOptions中分配值吗？
