Javascript 可以从同级元素上下文中选择jquery上下文中的文本吗？

例如，代码是：

<ul>
   <li><strong>This is a list header.</strong> And I want this text to disappear because this is not a list header!</li>
</ul>

---

我试图实现的是隐藏不在

中的文本，尝试将该文本包装在

span

中，然后执行以下操作：

HTML:

正如Rajaprabhu所说，将文本包装在一个跨度内，然后：

<ul>
   <li>
     <strong>This is a list header.</strong>
     <span>And I want this text to disappear because this is not a list header!</span>
   </li>
</ul>

<ul>
   <li>
     <strong>This is a list header.</strong>
     <span>And I want this text to disappear because this is not a list header!</span>
   </li>
</ul>

$('ul li >').hide().filter('strong').fadeIn();

<ul>
   <li>
     <strong>This is a list header.</strong>
     <span>And I want this text to disappear because this is not a list header!</span>
   </li>
</ul>

$('ul li >').filter(':not(strong)').hide();
