Question

我的WordPress网站上存在一个问题：https://nazim.skypage.in/

在移动设备上，当您切换菜单打开时，一旦开始向下滚动，它将立即消失。真正奇怪的是，它不会在Chrome检查器中发生，我可以在菜单上上下滚动。

任何指导都将非常有帮助。谢谢！

这是我的HTML源代码：

<nav class="clearfix" id='cssmenu'>
<div id="head-mobile"></div>
<div class="button">Menu</div>
<ul id="menu-main-menu" class="menu"><li id="menu-item-10" class="menu-item menu-item-type-custom menu-item-object-custom current-menu-item current_page_item menu-item-home menu-item-10"><a href="https://nazim.skypage.in/" aria-current="page">Home</a></li>
<li id="menu-item-237" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-237"><a href="https://example.com/blog/">Blog</a></li>
<li id="menu-item-313" class="menu-item menu-item-type-custom menu-item-object-custom menu-item-has-children menu-item-313"><a href="#">Link 1</a>
<ul class="sub-menu">
    <li id="menu-item-317" class="menu-item menu-item-type-custom menu-item-object-custom menu-item-317"><a href="#">Sub Menu</a></li>
</ul>
</li>
<li id="menu-item-314" class="menu-item menu-item-type-custom menu-item-object-custom menu-item-has-children menu-item-314"><a href="#">Link 2</a>
<ul class="sub-menu">
    <li id="menu-item-318" class="menu-item menu-item-type-custom menu-item-object-custom menu-item-318"><a href="#">Sub Menu</a></li>
</ul>
</li>
<li id="menu-item-315" class="menu-item menu-item-type-custom menu-item-object-custom menu-item-315"><a href="#">Link 3</a></li>
<li id="menu-item-316" class="menu-item menu-item-type-custom menu-item-object-custom menu-item-316"><a href="#">Link 4</a></li>
</ul></nav>

Answer 1

我在您的代码中找不到任何内容，因此这只是一个疯狂的猜测。但这听起来像是JavaScript问题。我认为当用户调整窗口大小时，菜单（及其样式）正在重置。大多数移动浏览器在滚动时都会隐藏网址栏，从而触发javascript中的窗口调整大小事件。

Answer 2

对我来说，SKeurentjes 的疯狂猜测是正确的。什么对我有用：

去掉js中的所有resize事件
重复菜单的 html，一个在类下，例如。 .menu.mobile，其他在 .menu.desktop 下。媒体查询不/显示每一个。
然后将不同的 js 行为绑定到 .menu 和 .desktop 类。

如何解决滚动移动菜单消失的问题？
