如何实现TailWind CSS购物车悬停下拉菜单移出后延迟2秒隐藏

改动说明 #

• 下拉容器默认添加hidden类实现初始隐藏
• 给购物车外层相对定位容器添加id="cartWrapper"用于JS元素选择
• 新增原生JS逻辑实现悬停显隐+延迟隐藏效果，鼠标重新移入会取消待执行的隐藏任务，避免用户操作下拉时菜单意外消失

<script>
// 购物车下拉显隐逻辑
const cartWrapper = document.getElementById('cartWrapper')
const cartDropdown = document.getElementById('cartDropdown')
let hideTimer = null

// 鼠标移入：清除待执行的隐藏任务，显示下拉
cartWrapper.addEventListener('mouseenter', () => {
  clearTimeout(hideTimer)
  cartDropdown.classList.remove('hidden')
})

// 鼠标移出：2秒后隐藏下拉
cartWrapper.addEventListener('mouseleave', () => {
  hideTimer = setTimeout(() => {
    cartDropdown.classList.add('hidden')
  }, 2000)
})
</script>

可调整说明 #

代码中setTimeout的2000对应2秒延迟，可根据业务需求自行修改数值调整等待时长。
