事件侦听器由于某种原因未启动

Question

我改编了Simply Nav(非常轻便的移动导航-感谢obscuredtour(的代码，使背景半透明覆盖逐渐消失，而不是随着导航滑入。

这很好，但我现在失去的是点击/点击半透明覆盖(在右手边(关闭整个导航的能力。

事件侦听器仍然存在——pageOverlay.addEventListener('click', toggleNav);——但它没有启动pageOverlay.classList.remove('-open');。

overlaydiv不再是父<ul class="nav-list">的子级，所以我不知道这是否与它有关

我尝试过在overlaydiv上创建一个透明的覆盖，并添加了一个eventlistener，但没有成功。

这是代码，如果有人有任何想法，我将非常感谢任何帮助。我还是个新手，所以毫无疑问这是显而易见的。非常感谢。

Answer 1

这实际上看起来像是一个css问题。标签<ul class="nav-list -open">的宽度为100%，因此它会填充整个屏幕，不允许鼠标点击来访问覆盖元素。您应该：

• 删除-open类上的width: 100%(问题的来源(
• 删除.list.-left上的width: 60%(导航的子项不会填充它，它没有太大意义…(
• 在.nav-list中设置left: -80rem而不是50rem(以完全隐藏它(

那会起作用的。
