Question

我正在尝试填充下拉列表，但我无法显示选项，我无法弄清楚原因。我用控制器填充控制器中的选项：

--exclude

然后在我的HTML中这样：

 var qOptions = [];
 if (value.vchChoice1 != '') {
    qOptions.push(value.vchChoice1);
  };
 if (value.vchChoice2 != '') {
    qOptions.push(value.vchChoice2);
  };
if (value.vchChoice3 != '') {
  qOptions.push(value.vchChoice3);
 };
if (value.vchChoice4 != '') {
  qOptions.push(value.vchChoice4);
  };
$scope.followingquestions[key].qOptions = qOptions;
   qOptions = [];

以下是整个HTML代码，以防有些内容导致选项出现然后消失：

<select ng-model="f.vchShortAnswer">
   <option value="">--Please Select--</option>
   <option ng-repeat="z in f.qOptions" value="{{z}}">{{z}}</option>
</select>

我知道f.qOptions中有值，我可以使用带有div标签的重复显示它们，但我不能让它们显示在下拉列表中。

我也尝试过以下但是仍然没有显示：

            <div ng-repeat="f in followingquestions">
            <div ng-switch="f.ClusterTypeID">
                <div ng-switch-when="1048576">
                    <div class="row row-relative">
                        <div class="col-md-12">
                            <div ng-bind-html="f.vchQuestionText | trustedhtml"></div><br />
                            <div>
                                <table>
                                    <thead style="background-color:#b1d6f1">
                                        <tr>
                                            <th>{{headers.vchTextElementOneHeader}}</th>
                                            <th>{{headers.vchTextElementTwoHeader}}</th>
                                        </tr>
                                    </thead>
                                    <tbody>
                                        <tr ng-repeat="answ in headers.Answers">
                                            <td>{{answ.vchTextElementOne}}</td>

            </div>
        </div>

更奇怪的是...数值短暂显示，然后消失了！

我认为我在这里缺少一些简单的东西，因为我在选择选项列表中显示了其他列表，就像我上面尝试的那样。非常感谢任何帮助！

 $scope.qOptions = [];
 if (value.vchChoice1 != '') {
     $scope.qOptions.push(value.vchChoice1);
 };
 if (value.vchChoice2 != '') {
     $scope.qOptions.push(value.vchChoice2);
 };
 if (value.vchChoice3 != '') {
     $scope.qOptions.push(value.vchChoice3);
 };
 if (value.vchChoice4 != '') {
     $scope.qOptions.push(value.vchChoice4);
 };
 $scope.followingquestions[key].qOptions = $scope.qOptions;


 <select ng-options="z as z for z in f.qOptions" ng-model="f.vchShortAnswer">
   <option value="">--Please Select--</option>
