如何在单击而不是悬停时打开 Superfish jQuery 菜单? [英] How can I open a Superfish jQuery Menu on click rather than hover?

问题描述

我在网上快速浏览了 Joel Birch 的 Superfish 菜单实现，该菜单适用于点击，而不是悬停.

I've had a quick browse around the web for an implementation of Superfish menu by Joel Birch that works on onclick, rather than hover.

在 Github 上找到 Karl Swedberg 提供的这个链接，看起来像票.

Found this link by Karl Swedberg at Github, which looks like the ticket.

https://gist.github.com/917446

它就像一个魅力，直到我点击一个活动链接，然后菜单关闭，并且似乎返回 false.

It works like a charm, right up to the point where I click on an active link, at that point the menu closes, and appears to return false.

我怎样才能让它导航到实际的链接目的地?

How can I get it to navigate to the actual link destination?

推荐答案

更改这一行(第 21 行，超过函数):

Changing this line (line 21, over function):

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

为此:

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

用于单击菜单的完整 superfish 代码:
