当我点击菜单中的 a 时关闭我的 span

Question

几天前我制作了一个响应式菜单，它运行良好，除了当我在我创建的 menu-ul 中单击我的 a 时，它关闭了菜单但没有关闭我的汉堡菜单跨度的状态。

这是代码，你可以理解

function openNav(){
    document.getElementById('menu-ul').classList.toggle("open");
}

body {
  display: grid; 
}

#back-top {
  position: fixed;

  width: 35px; 
  height: 35px;
  text-align: center;
  font-size: 45px;
  font-family: 'Agency FB', arial;
  line-height: 32px;
  background: #22cfb5;

有人可以帮我解决这个问题吗？我已经检查了一些接近我的主题，但没有找到解决我问题的答案。非常感谢你！ :)

Answer 1

发生这种情况是因为如果您单击菜单项，您的复选框没有被取消选中。您可以这样修改函数：

function openNav(){
  const menuUl = document.getElementById('menu-ul');
  const burger = document.getElementById('burger');

  if (menuUl.classList.contains('open')) {
        burger.checked = false;
  }
    
  menuUl.classList.toggle('open');
}

并添加 id-attribute 到 input[type="checkbox"]:

<input id="burger" type="checkbox" onclick="openNav()"/>

希望对您有所帮助！

Answer 2

您可以通过如下的小改动来实现。

第 1 步：创建函数 toggleMenu() 来切换负责动画的复选框。

第 2 步：将上述功能添加到所有锚标记，如 onclick="toggleMenu()".

请检查演示。

function openNav(){
    document.getElementById('menu-ul').classList.toggle("open");
}

function toggleMenu() {
    document.getElementsByClassName('menu')[0].getElementsByTagName('input')[0].checked = !document.getElementsByClassName('menu')[0].getElementsByTagName('input')[0].checked;
    openNav();
}

body {
  display: grid;
