我有以下html：
<div id="secondary">
<ul class="simple-pages-navigation">
<li class="nav-das-projekt current"><a href="/projekt">Das Projekt</a>
<ul class="subnav-1">
<li class="nav-ber-kaschau"><a href="/ber-kaschau">Über Kaschau</a></li>
<li class="nav-projektpartner"><a href="/projektpartner">Projektpartner</a></li>
</ul>
</li>
<li class="nav-projektu"><a href="/projekt_sk">Projekt</a>
<ul class="subnav-1">
<li class="nav-o-koiciach"><a href="/ber-kaschau_sk">O Košiciach</a></li>
<li class="nav-o-koiciach"><a href="/partneri_sk">O Košiciach</a></li>
</ul>
</li>
<li class="nav-project"><a href="/projekt_en">Project</a>
<ul class="subnav-1">
<li class="nav-o-koiciach"><a href="/ber-kaschau_en">About Kaschau</a></li>
<li class="nav-o-koiciach"><a href="/partner_en">Project Partners</a></li>
</ul>
</li>
</ul>
</div>
I want to add css `display:none;` via jQuery to all parent-parent tags whose daughter-tags have a link ending with `"_sk"` or `"_en"` in it.
the result should look like this:
<div id="secondary">
<ul class="simple-pages-navigation">
<li class="nav-das-projekt current"><a href="/projekt">Das Projekt</a>
<ul class="subnav-1">
<li class="nav-ber-kaschau"><a href="/ber-kaschau">Über Kaschau</a></li>
<li class="nav-projektpartner"><a href="/projektpartner">Projektpartner</a></li>
</ul>
</li>
<li class="nav-projektu" style="display: none"><a href="/projekt_sk">Projekt</a>
<ul class="subnav-1">
<li class="nav-o-koiciach"><a href="/ber-kaschau_sk">O Košiciach</a></li>
<li class="nav-o-koiciach"><a href="/partneri_sk">O Košiciach</a></li>
</ul>
</li>
<li class="nav-project" style="display: none"><a href="/projekt_en">Project</a>
<ul class="subnav-1">
<li class="nav-o-koiciach"><a href="/ber-kaschau_en">About Kaschau</a></li>
<li class="nav-o-koiciach"><a href="/partner_en">Project Partners</a></li>
</ul>
</li>
</ul>
</div>
=== 编辑：===
我添加了更多 HTML，现在是答案
$('a[href$="_sk"], a[href$="_hu"]').parent().hide();
不适用于此 html 代码，我不知道为什么，因为它仍然适用于以“_sk”结尾的标签链接，但不适用于带有“_hu”的链接：
