Javascript 在 phone 上展开站点菜单的按钮

Question

我正在为我的网站使用在线大型菜单，整个代码是 here

<a href="javascript:void(0);" class="ic menu">
<span class="line"></span>
<span class="line"></span>
<span class="line"></span>
</a>
<a href="javascript:void(0);" class="ic close"></a>

在移动设备上，它有一个类似于应用程序按钮的按钮，用于打开菜单。问题是它在桌面上运行，但在我的智能手机上打不开。

有什么办法可以解决问题吗？谢谢！

Answer 1

此处使用 CSS 打开菜单开发者使用了 :hover，并且在 phones 内不会出现悬停，因此您需要将 :hover css 替换为 :active对于 phone，参见 codepen

问题出在IOS

.ic.menu:focus // If you want a real focus state to a element,
               // you can add a tabindex attribute to it.

示例：

    <a href="javascript:void(0);" class="ic menu" tabindex="1">
<span class="line"></span>
<span class="line"></span>
<span class="line"></span>
</a>
<a href="javascript:void(0);" class="ic close" tabindex="1"></a>
