有没有办法代替<li> <button> 元素？

Question

有没有一种方法可以使用<li>而不是<button>元素，并且仍然可以获得与使用按钮相同的结果？

我有一个导航栏，在导航栏的中间，有一个按钮，因为我有下拉菜单(一旦你点击按钮，下拉菜单就会显示出来(，我想把按钮变成一个列表项，以便获得与导航栏其他部分完全相同的外观(CSS(。

Answer 1

在这里，您必须学习JS，它最适合操作DOM。你所需要的一切都在这里，SO已经回答了。

1. 使用CSS，我隐藏除第一个li项目外的所有项目
2. 然后在JS中，我将ul元素保存在nav变量中

let nav = document.querySelector("#nav-menu .products ul")

3. 将事件侦听器添加到第一个li项

nav.querySelector("li:first-of-type").addEventListener("click", function() {

4. 如果按下，则显示其余部分：

nav.querySelectorAll("li").forEach(li => li.style.display="block")

let nav = document.querySelector("#nav-menu .products ul")
nav.querySelector("li:first-of-type").addEventListener("click", function() {
nav.querySelectorAll("li").forEach(li => li.style.display="block")
});

#nav-menu .products ul li:not(li:first-of-type){
display:none}
