如何通过单击而不是悬停来打开 Superfish jQuery 菜单？

Question

我在网上快速浏览了一下 Joel Birch 实现的 Superfish 菜单，该菜单适用于单击，而不是悬停。

在 Github 上找到了 Karl Swedberg 的这个链接，看起来像票。

https://gist.github.com/917446

它就像一个魅力，直到我点击一个活动的点链接，此时菜单关闭，并且似乎返回 false。

我怎样才能让它导航到实际的链接目的地？

Answer 1

Karl 在 GitHub 上发布了一个快速更新来帮助我解决问题：https://gist.github.com/652684对我来说不太管用。

从下面的链接获取我的工作代码。

已更新..以防链接失效..

Answer 2

更改此行（第 21 行，函数上方）：

$.showSuperfishUl().siblings().hideSuperfishUl();

为此：

$.click(function(){$(this).showSuperfishUl().siblings().hideSuperfishUl();});

Answer 3

如果有人在使用 drupal 中的 superfish 模块时来这里寻找这个答案（我正在使用 drupal 8 模块）。我根本没有修改superfish库。我在我的 js 文件中做了以下操作，它似乎工作正常（在 chrome 和 firefox 上测试）。

下面的代码禁用鼠标悬停时下拉菜单。当您单击父菜单项时，菜单会下拉并且实际上不会转到父级 href。

$('#superfish-main > li > a.menuparent').on('mouseover click', function(event) {
  return false;
});

我不使用 superfish 作为我的移动菜单，因此我没有在移动设备上测试上述内容，但我想您需要做一些工作才能按照您想要的方式获得它。

编辑

由于某种原因，以上内容不适用于 Safari。以下适用于 chrome、safari 和 firefox

$('#superfish-main > li > a').on('mouseover', function(event) {
  return false;
});
$('#superfish-main > li > a.menuparent').on('click', function(event) {
  // Close any open dropdown menus.
  $.each($(this), function(index, element) {
    $(element).parent().parent().find('li.menuparent > ul').addClass('sf-hidden');
  });
  // Open the clicked dropdown menu.
  $(this).next().removeClass('sf-hidden');
  event.preventDefault();
});
