Angularjs 更新指令中的ng repeat对象属性

我有一份清单，上面有来自JSON的多个问题：

 <div class="tab-pane fade in active" id="tab1">
    <div class="row">
       <div class="col-sm-12">
          <h3>{{list.titel}}</h3>

          <table class="table table-striped table-responsive">
            <tr ng-repeat="question in list.questions">
                <td>{{question.label}}</td>
                <td ng-if="question.checkboxes.length > 0">
                    <div class="form-check" ng-repeat="checkbox in question.checkboxes">
                        <input type="checkbox" class="form-check-input" ng-model="checkbox.value">
                            <label class="form-check-label">{{checkbox.text}}</label>
                    </div>
                </td>

                <td ng-if="question.checkboxes.length < 1">
                    <input type="text" ng-model="question.value" class="form-control">
                </td>
            </tr>
          </table>
         </div>
      </div>
     </div>

该指令返回图像的路径。 我想将图像存储在问题列表的JSON结构中。 但我怎么知道这张照片是在哪个问题上拍摄的呢？

是否有存储位置的方法，例如：

列表。问题[4]。imagepath

？

这应该适合您。将模型解析为指令并设置新的对象属性

看法

你的

数据在哪里？我的指令

指令？@lin，对不起，是“我的指令”指令。你救了我的周末！
