Question

对不起，我的英语。我正在使用UI-Select选择框来查看数据，但是我正在使用ng-model值打印未定义的数据。我正在使用基本数组。

Answer 1

可以通过在控制器中初始化一个对象并更新该对象的属性而不是直接更新范围变量来解决此问题。

请访问此link了解更多信息。

下面是该解决方案的有效示例。

'use strict';

var app = angular.module('demo', ['ngSanitize', 'ui.select']);

app.controller('DemoCtrl', function($scope, $http, $timeout, $interval) {
  $scope.karthi = [1, 2, 3, 4, 5, 6, 10];
  $scope.ctrl = {};
});
