如何在单击子项时使用jQuery将类添加到父元素？

I have menu structure like below:

我有如下菜单结构：

<ul class="sub-menu" style="display: none;">
<li class="menu-item menu-item-type-post_type menu-item-object-page current-menu-item page_item page-item-1564 current_page_item menu-item-5230" id="menu-item-5230"><a href="http://artofsujatha.wpstag.sirahu.net/curriculam-vitae/" title="Curriculam VItae">Curriculam VItae</a></li>
<li class="menu-item menu-item-type-post_type menu-item-object-page menu-item-5231" id="menu-item-5231"><a href="http://artofsujatha.wpstag.sirahu.net/bio/" title="Bio">Bio</a></li>
<li class="menu-item menu-item-type-post_type menu-item-object-page menu-item-5232" id="menu-item-5232"><a href="http://artofsujatha.wpstag.sirahu.net/artist-statement/" title="Artist Statement">Artist Statement</a></li>
</ul>

When I click any LI elements within the UL, I need to add class "active" to the UL element. How can I do this in jQuery?

当我点击UL中的任何LI元素时，我需要将类“active”添加到UL元素。我怎么能在jQuery中做到这一点？

Maybe something like this?

也许是这样的？

$(function() {
    function updateMenu() {
        $('ul.sub-menu.active').removeClass('active');
        $('li.current-menu-item').parent('ul.sub-menu').addClass('active');
    }

    $('li.menu-item').click(function(e) {
        // prevent page from redirect
        e.preventDefault();

        // set new current-menu-item
        $(this).siblings().removeClass('current-menu-item');
        $(this).addClass('current-menu-item');

        // and update active menu according the current-menu-item
        updateMenu();
    });

    updateMenu();
});
