我有一个垂直轮播菜单，其中两个项目打开以显示子菜单。当您将鼠标悬停在菜单外时，它们会再次关闭并返回正常菜单状态。

我正在寻找的是一种让它悬停并保持打开状态的方法，然后当另一个菜单悬停时，它们关闭并且悬停激活......

因为我正在使用 Joomla！同样，显示网站等可能会很棘手，但这里是 JavaScript，希望如果需要更多信息，我可以发布它。谢谢！

<script type="text/javascript">
$(function(){
  $("ul li.parent").hover(function(){
     $(this).children("ul").slideDown(300);
     $(".contact-details-container p").fadeOut(200);
  },function(){
     $(this).children("ul").stop(true, true).slideUp(300); 
     $(".contact-details-container p").stop(true, true).fadeIn(2000);
  });
});
</script>

在悬停功能中，为什么不添加一个具有属性的新类display:block。在设置此之前，请为已具有所选类的任何打开的子菜单调用关闭函数。

它可能看起来像这样：

$(function () {
     $("ul.menu-main > li").hover(function () {
        //Don't do this again if the same menu is hovered
        if (!$(this).hasClass('selected')) {
            //Ensure any open sub-menu is closed.
            $("li.selected").children("ul").stop(true, true).slideUp(300);
            $(".contact-details-container p").stop(true, true).fadeIn(2000);
            $("li.selected").removeClass('selected');

            //Open sub-menu
            $(this).addClass('selected');
            $(this).children("ul").slideDown(300);
            $(".contact-details-container p").fadeOut(200);
        }
    });
});

编辑：由于（我认为）您的菜单的工作方式，您实际上不需要该display:block属性，但您仍然需要该类来识别打开的子菜单，以便您可以应用您的效果。
