隐藏元素并同时触发点击事件

Question

我正在尝试构建一个简单的下拉菜单，当将鼠标悬停在 div 上时会显示该下拉菜单。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所见，我仅使用 CSS 完成了此操作。

但是，我希望当用户单击其中一个下拉元素时会发生两件事：

1. 下拉菜单已关闭/隐藏

2. 触发点击事件

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;

}

<div class="shop-selector">

  <div class="shop-dropdown">

    <div class="shop">

      Shop Nameone

    </div>

    <div class="shop">

      Shop Nametwo

    </div>

    <div class="shop">

      Shop Namethree

    </div>

  </div>

</div>

Answer 1

单击将不起作用。因为悬停是由鼠标完成的，因此，尝试使用鼠标事件，如“mousedown”？...让我们检查一下。

我认为这就是你所需要的。我删除了您的 css:active类定义，并在此行.active顶部添加了一个自定义类，shop-selector只是为了显示您的下拉列表.shop-selector.active .shop-dropdown。切换.active类和printConsole=>的小 jsaddActionconst menu = document.getElementById('menu');menu.addEventListener('mouseenter', e => {&nbsp; e.target.classList.add('active')});menu.addEventListener('mouseleave', e => {&nbsp; e.target.classList.remove('active')});// this is what you neededfunction addAction() {&nbsp;&nbsp; console.log('Event triggered');&nbsp; menu.classList.remove('active');}document.querySelectorAll('.shop').forEach(&nbsp; shop => shop.addEventListener('click', addAction ));.shop-selector svg {&nbsp; padding: 2px;&nbsp; border-radius: 50%;&nbsp; background-color: orange;&nbsp; display: block;&nbsp; height: 2rem;&nbsp; width: 2rem;}.shop-selector .shop-dropdown {&nbsp; position: absolute;&nbsp; display: flex;&nbsp; flex-direction: column;&nbsp; justify-content: space-evenly;&nbsp; align-items: flex-start;&nbsp; z-index: 1;&nbsp; transition: all 0.7s;&nbsp; visibility: hidden;&nbsp; opacity: 0;}.shop-selector.active .shop-dropdown {&nbsp; visibility: visible;&nbsp; opacity: 1;}.shop-selector .shop-dropdown .shop {&nbsp; margin: 5px 0 0;&nbsp; padding: 2px 5px;&nbsp; border-radius: 3px;&nbsp; background-color: orange;}<div class="shop-selector" id="menu">&nbsp; <svg xmlns="http://www.w3.org/2000/svg" enable-background="new 0 0 24 24" viewBox="0 0 24 24" fill="black" width="18px" height="18px"><g><path d="M0,0h24v24H0V0z" fill="none"/><path d="M19.14,12.94c0.04-0.3,0.06-0.61,0.06-0.94c0-0.32-0.02-0.64-0.07-0.94l2.03-1.58c0.18-0.14,0.23-0.41,0.12-0.61 l-1.92-3.32c-0.12-0.22-0.37-0.29-0.59-0.22l-2.39,0.96c-0.5-0.38-1.03-0.7-1.62-0.94L14.4,2.81c-0.04-0.24-0.24-0.41-0.48-0.41 h-3.84c-0.24,0-0.43,0.17-0.47,0.41L9.25,5.35C8.66,5.59,8.12,5.92,7.63,6.29L5.24,5.33c-0.22-0.08-0.47,0-0.59,0.22L2.74,8.87 C2.62,9.08,2.66,9.34,2.86,9.48l2.03,1.58C4.84,11.36,4.8,11.69,4.8,12s0.02,0.64,0.07,0.94l-2.03,1.58 c-0.18,0.14-0.23,0.41-0.12,0.61l1.92,3.32c0.12,0.22,0.37,0.29,0.59,0.22l2.39-0.96c0.5,0.38,1.03,0.7,1.62,0.94l0.36,2.54 c0.05,0.24,0.24,0.41,0.48,0.41h3.84c0.24,0,0.44-0.17,0.47-0.41l0.36-2.54c0.59-0.24,1.13-0.56,1.62-0.94l2.39,0.96 c0.22,0.08,0.47,0,0.59-0.22l1.92-3.32c0.12-0.22,0.07-0.47-0.12-0.61L19.14,12.94z M12,15.6c-1.98,0-3.6-1.62-3.6-3.6 s1.62-3.6,3.6-3.6s3.6,1.62,3.6,3.6S13.98,15.6,12,15.6z"/></g></svg>&nbsp; <div class="shop-dropdown">&nbsp; &nbsp; <div class="shop">&nbsp; &nbsp; &nbsp; Shop Nameone&nbsp; &nbsp; </div>&nbsp; &nbsp; <div class="shop">&nbsp; &nbsp; &nbsp; Shop Nametwo&nbsp; &nbsp; </div>&nbsp; &nbsp; <div class="shop">&nbsp; &nbsp; &nbsp; Shop Namethree&nbsp; &nbsp; </div>&nbsp; </div></div>

Answer 3

您是否尝试过代理单击处理程序，并在菜单列表上使用切换类而不是使用 :active 作为菜单项？我认为这应该是正确的方向。
