Question

我有这个问题：在HTML页面中我有两个选择，第二个选择取决于第一个

HTML

FIRST

<select class="trip dark" ng-model="formSearch.selectedRegione" ng-options="regione.nome for regione in regioni.regionSelector">
                                            <option value="">TUTTE</option>
                                        </select>

SECOND

<select class="trip dark" ng-model="formSearch.selectProvincia" ng-options="provincia.nome for provincia in formSearch.selectedRegione.province">
                                            <option value="">TUTTE</option>
                                        </select>

问题是，当我从我的控制器中获取选定值时，它会返回第一个对象并且未定义＆＃39;对于第二个，而不是我期望的价值。

修改

所有两个选项都可以正常工作，这意味着当我在第一个选择中选择一个值时，第二个选择了正确的值。

我的问题是在我的控制器中我这样做了

var selectedRegione= $scope.formSearch.selectedRegione;
var selectedProvincia= $scope.formSearch.selectedProvincia;

selectedRegione返回对象，selectedProvincia返回undefined

修改

HTML

<div ng-controller="mainController">

<div class="holder">
    <select class="trip dark" ng-model="formSearch.selectedRegione" ng-
      options="regione.nome for regione in regioni.regionSelector">
      <option value="">TUTTE</option>
    </select>
</div>
<div class="holder">
    <select class="trip dark" ng-model="formSearch.selectProvincia" ng-
      options="provincia.nome for provincia in formSearch.selectedRegione.province">
    <option value="">TUTTE</option>
    </select>
</div>

<button class="btn btn-trip" ng-click="ricercaAttivita()">Ricerca</button>

<div>

CONTROLLER

var tantoSvagoApp = angular.module('tantoSvagoApp', ['ui.bootstrap', 'ui-rangeSlider']);

tantoSvagoApp.controller("mainController", function ($scope, serviceRegioni, 
                        srvShareData, $location, $window) {

$scope.ricercaAttivita = function() {
    var selectedRegione= $scope.formSearch.selectedRegione;
    var selectedProvincia= $scope.formSearch.selectedProvincia;

    console.log("selectedRegione  " + selectedRegione );
    console.log("selectedProvincia  " + selectedProvincia );
}
});

对象中的selectedRegione，未定义的selectedProvincia
