切换时重新加载div

Question

我的页面上有一个切换选项，如下所示：

<div class="jumbotron">
  <div class="btn-group">
    <label class="btn btn-primary" id="singleChoose" ng-model="radioModel" ng-change="toggleMode()" btn-radio="'Single'">Single</label>
    <label class="btn btn-primary" id="bulkChoose" ng-model="radioModel" ng-change="toggleMode()" btn-radio="'Bulk'">Bulk</label>
  </div>
  <form id="singleContentForm" name="singleContentForm">
    <div id="singleContent" class="vertical">
      <div id="republish_alert_success" role="alert">
        <img src="images/DataServicesAdminAppSuccess.png" width="40" height="40" alt="" />
        <strong>Success!</strong> Policy republished.
      </div>
    </div>
  </form>
  <form id="bulkContentForm" name="bulkContentForm">
    <div id="bulkContent" class="horizontal">
      <select class="custom-select" ng-model="republishSource" ng-options="choice.name for choice in republishSources"></select>
      <div class="col-md-6">
        <input id="republishUpload" required="true" type="file" class="form-control" placeholder="Upload republish file" file-model="uploadedRepublishFile" accept=".csv, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.ms-excel"
        />
      </div>
      <div aria-label="file upload">
        <input id="republish" type="submit" class="btn btn-success" ng-click="doRepublishFile()" value="Republish" />
      </div>
    </div>
  </form>
</div>

我希望在选择指定的div的切换开关时重新加载div。

即，当我选择 Single 时，应在渲染之前重新加载 Single 。

有人可以帮我吗？
