如何在点击而不是悬停时打开Superfish jQuery菜单？

Question

我已经在网上快速浏览了Joel Birch实施的Superfish菜单，该菜单适用于onclick，而不是悬停。

在Github找到Karl Swedberg的链接，看起来就像是票。

https://gist.github.com/917446

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

如何让它导航到实际的链接目的地？

Answer 1

Karl发布了一个快速更新来帮助我解决GitHub ..在这里：https://gist.github.com/652684对我来说不太有效。

从以下链接中获取我的工作代码。

http://www.nilinks.com/home-owner/wp-content/themes/acheson/js/superfish.js

更新..只是因为链接永远死了..

Answer 2

更改此行（第21行，超过函数）：

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

对此：

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

Answer 3

如果有人来这里在drupal中使用superfish模块时正在寻找答案（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）。

以下代码在鼠标悬停时禁用了下拉菜单。当您单击父菜单项时，菜单将下拉，并且实际上不会转到父href。

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

我不使用superfish作为移动菜单，因此我尚未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需获得它。

编辑

由于某种原因，以上内容不适用于野生动物园。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();
});
