您可以使用input-group：

<div class="input-group">
  <input type="text" class="form-control">
  <span class="input-group-btn">
    <button class="btn btn-default" type="button">Abschicken</button>
  </span>
</div><!-- /input-group -->

Du kannst input-groupdafürnutzen：

<div class="input-group">
  <input type="text" class="form-control">
  <span class="input-group-btn">
    <button class="btn btn-default" type="button">Abschicken</button>
  </span>
</div><!-- /input-group -->
