隐藏元素同时触发点击事件

Question

我正在尝试构建一个简单的下拉菜单，当鼠标悬停在 div 上时会显示该菜单。当鼠标悬停在 div 或任何下拉元素上时，此下拉菜单应保持打开状态。正如您在下面的代码片段中看到的那样，我仅使用 CSS 完成了此操作。

但是，当用户单击其中一个下拉元素时，我预计会发生两件事：

下拉菜单是closed/hidden
点击事件被触发

我尝试使用 :active 伪类来隐藏下拉菜单。但如果我这样做，则不会触发点击事件。

如何既隐藏下拉菜单又触发点击事件？

function printConsole() { 
  console.log('Event triggered');
}

document.querySelectorAll('.shop').forEach(
  shop => shop.addEventListener('click', printConsole)
);

.shop-selector svg {
  padding: 2px;
  border-radius: 50%;
  background-color: orange;
  display: block;
  height: 2rem;
  width: 2rem;
}

.shop-selector svg:hover+.shop-dropdown {
  visibility: visible;
  opacity: 1;
}

.shop-selector .shop-dropdown {
  position: absolute;
  display: flex;
  flex-direction: column;
  justify-content: space-evenly;
  align-items: flex-start;
  z-index: 1;
  transition: all 0.7s;
  visibility: hidden;
  opacity: 0;
}

.shop-selector .shop-dropdown:hover {
  visibility: visible;
  opacity: 1;
}

.shop-selector .shop-dropdown:active {
  display: none;
}

.shop-selector .shop-dropdown .shop {
  margin: 5px 0 0;
  padding: 2px 5px;
  border-radius: 3px;
  background-color: orange;
}

Answer 1

点击不会work.Because悬停是通过鼠标完成的，因此，尝试使用“mousedown”之类的鼠标事件？ ...让我们检查一下。

Answer 2

您是否尝试代理点击处理程序，并在菜单列表上使用切换 class 而不是对菜单项使用 :active？我认为这应该是正确的方向。

Answer 3

我想这就是你需要的。

我删除了你的 css :active class defs 并在 shop-selector 这一行之上添加了一个自定义 .active class 只是为了显示您的下拉菜单 .shop-selector.active .shop-dropdown.

切换 .active class 和 printConsole => addAction

的小 js

const menu = document.getElementById('menu');
menu.addEventListener('mouseenter', e => {
  e.target.classList.add('active')
});

menu.addEventListener('mouseleave', e => {
  e.target.classList.remove('active')
});

// this is what you needed
function addAction() { 
  console.log('Event triggered');
  menu.classList.remove('active');
}

document.querySelectorAll('.shop').forEach(
  shop => shop.addEventListener('click', addAction )
);

.shop-selector svg {
  padding: 2px;
  border-radius: 50%;
  background-color: orange;
  display: block;
  height: 2rem;
  width: 2rem;
}

.shop-selector .shop-dropdown {
  position: absolute;
  display: flex;
  flex-direction: column;
  justify-content: space-evenly;
  align-items: flex-start;
  z-index: 1;
  transition: all 0.7s;
  visibility: hidden;
  opacity: 0;
}


.shop-selector.active .shop-dropdown {
  visibility: visible;
  opacity: 1;
}

.shop-selector .shop-dropdown .shop {
  margin: 5px 0 0;
  padding: 2px 5px;
  border-radius: 3px;
  background-color: orange;
}
