我有一个弹出菜单,我试图使用鼠标悬停事件切换,但它似乎不按预期工作。我尝试使用CSS的悬停事件,通过像这样定位div:
然而,这不起作用。关于我如何解决这个/改进这个有什么建议吗?由于
const flyoutLink = document.querySelector('.flyout-link');
const flyoutMenu = document.querySelector('.flyout-menu');
flyoutLink.addEventListener('mouseover', () => {
flyoutMenu.classList.toggle('.flyout-menu-show');
})
.grid-hero-wrapper {
grid-template-columns: 100px 1fr;
gap: 15px;
margin-top: 15px;
display: grid;
}
.hero-categories-block {
background: #fff;
border: 1px solid #28282b;
}
.hero-categories-list {
display: flex;
flex-direction: column;
padding: 5px 0;
height: 100%;
}
.flyout-menu-show {
opacity: 1;
visibility: visible;
}
.flyout-menu {
background: #fff;
border: 1px solid #28282b;
position: absolute;
top: 0;
width: 100%;
height: 100%;
opacity: 0;
visibility: hidden;
position: absolute;
z-index: 999;
}
.hero-categories-list a {
display: flex;
align-items: center;
flex-grow: 1;
font-size: 0.75rem;
height: 22px;
color: #333;
}
.hero-slider-block {
position: relative;
}

这不起作用,因为你的css选择器的特殊性。
.flyout-menu-show 飞出菜单选择器,它们有相同的特异性。所以只有最新的才适用于你的元素。
改变.flyout-menu-show {
opacity: 1;
visibility: visible;
}
.flyout-menu.flyout-menu-show {
opacity: 1;
visibility: visible;
}
这将创建一个具有更高特异性的选择器,并且它将被正确应用:)。示例的工作代码:https://codepen.io/aSH-uncover/pen/PoaboWo
