Flyout-Menü mit Mouseover-Ereignis anzeigen

Ich habe ein Popup-Menü und versuche, Mouseover-Ereignisse zu verwenden, um es umzuschalten, aber es scheint nicht wie erwartet zu funktionieren. Ich habe versucht, CSS-Hover-Ereignisse zu verwenden, indem ich das Div wie folgt positioniert habe: .hero-list-block a:hover + .flyout-menu

Aber es nützt nichts. Irgendwelche Vorschläge, wie man das Problem beheben/verbessern kann? Danke

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;
}

    由于 css 选择器的特殊性,这不起作用。

    .flyout-menu-show 选择器在 .flyout-menu 选择器之前声明,并且它们具有相同的特异性。因此,只有最新的适用于您的元素。

    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:)。示例的工作代码笔: https://codepen.io/aSH-uncover/pen/PoaboWo< /a>
