我有一个包含 app-ngx-editor 的表单，我认为除了用户在未设置值的情况下从编辑器中选择/单击之外，我一切正常。我的输入框工作正常，当您点击/单击它时，框上的边框变为红色。现在，当您在编辑器中单击/单击时，它只会在框的左侧放置两条垂直的红线，见下图。

有没有办法获得我在输入框中看到的行为并将其应用于 app-ngx-editor？

        <button id="editCreateSubmitButton" type="submit" class="btn btn-default" [disabled]="!workItemForm.form.valid">{{isNew ? 'Save' : 'Update'}}</button>
      </div>
    </div>
  </form>
</div>

CSS：

.ng-invalid.ng-touched:not(form) {
    border: 1px solid red;
}
