Question

如果相应的Div中没有内容，我只想隐藏导航标签。我需要这样做，因为内容目前由Wordpress中的自定义帖子类型填充，因此不会有所有内容显示。

    <div role="tabpanel">

  <!-- Nav tabs -->
  <ul class="nav nav-tabs" role="tablist">
    <li role="presentation" class="active"><a href="#home" aria-controls="home" role="tab" data-toggle="tab">Home</a></li>
    <li role="presentation"><a href="#profile" aria-controls="profile" role="tab" data-toggle="tab">Profile</a></li>
    <li role="presentation"><a href="#messages" aria-controls="messages" role="tab" data-toggle="tab">Messages</a></li>
    <li role="presentation"><a href="#settings" aria-controls="settings" role="tab" data-toggle="tab">Settings</a></li>
  </ul>

  <!-- Tab panes -->
  <div class="tab-content">
    <div role="tabpanel" class="tab-pane active" id="home">...</div>
    <div role="tabpanel" class="tab-pane" id="profile">...</div>
    <div role="tabpanel" class="tab-pane" id="messages">...</div>
    <div role="tabpanel" class="tab-pane" id="settings">...</div>
  </div>

</div>

如果例如div #profile没有内容，我希望隐藏个人资料的导航标签li。

谢谢！

您可以使用:empty选择器查找空的tabpanel元素。然后，您需要循环覆盖这些以隐藏相关选项卡。试试这个：

$('.tab-pane:empty').each(function() {
    $('.nav-tabs a[href="#' + this.id + '"]').closest('li').hide();
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div role="tabpanel">
    <!-- Nav tabs -->
    <ul class="nav nav-tabs" role="tablist">
        <li role="presentation" class="active"><a href="#home" aria-controls="home" role="tab" data-toggle="tab">Home</a></li>
        <li role="presentation"><a href="#profile" aria-controls="profile" role="tab" data-toggle="tab">Profile</a></li>
        <li role="presentation"><a href="#messages" aria-controls="messages" role="tab" data-toggle="tab">Messages</a></li>
        <li role="presentation"><a href="#settings" aria-controls="settings" role="tab" data-toggle="tab">Settings</a></li>
    </ul>
    <!-- Tab panes -->
    <div class="tab-content">
        <div role="tabpanel" class="tab-pane active" id="home">Home</div>
        <div role="tabpanel" class="tab-pane" id="profile"></div>
        <div role="tabpanel" class="tab-pane" id="messages">Messages</div>
        <div role="tabpanel" class="tab-pane" id="settings"></div>
    </div>
</div>
