多个内容滑动轮播图【前端】

前几天写的前端项目当中自己写了一个比较好用的轮播组件，分享给大家 

图片具有点击效果和滑动效果，这里作者放了9张图片，大家有需要可以使用~ 

图片在这里大家可以直接进行测试 

 总组件代码：

这里的代码作者用的是Vue3，大家没有学过的可以使用al给你转成正常的js代码~~~ 

<script setup>
import { onMounted, onUnmounted } from 'vue'
onMounted(() => {
  const container = document.querySelector('.product_box')
  const leftIcon = document.querySelector('.left_icon')
  const rightIcon = document.querySelector('.right_icon')
  const items1 = document.querySelectorAll('.product_detail')
  const itemCount = items1.length
  let currentIndex = 0
  let isAnimating = false
  let autoSlideInterval
  let visibleItems = 3 // 初始值

  // 初始化
  updateCarousel()

  // 监听视窗大小变化
  window.addEventListener('resize', () => {
    updateCarousel()
  })

  function updateCarousel() {
    if (isAnimating) return
    isAnimating = true

    // 计算位移百分比（每个项目占 1/visibleItems）
    const translateX = -currentIndex * (100 / visibleItems / 1.07)
    container.style.transform = `translateX(${translateX}%)`
    container.style.transition = '1s'

    // 重置动画状态
    setTimeout(() => {
      isAnimating = false
    }, 500)
  }

  function nextSlide1() {
    stopAutoSlide()
    if (currentIndex >= itemCount - visibleItems) {
      // 到达最后时回到第一个
      currentIndex = 0
    } else {
      currentIndex++
    }
    updateCarousel()
    startAutoSlide()
  }

  function prevSlide1() {
    stopAutoSlide()
    if (currentIndex <= 0) {
      // 到达第一个时跳到最后
      currentIndex = itemCount - visibleItems
    } else {
      currentIndex--
    }
    updateCarousel()
    startAutoSlide()
  }

  function startAutoSlide() {
    autoSlideInterval = setInterval(nextSlide1, 3000) // 每3秒切换一次
  }

  // 停止自动轮播的函数
  function stopAutoSlide() {
    if (autoSlideInterval) {
      clearInterval(autoSlideInterval)
      autoSlideInterval = null
    }
  }

  // 添加按钮事件
  rightIcon.addEventListener('click', nextSlide1)
  leftIcon.addEventListener('click', prevSlide1)

  startAutoSlide()

  onUnmounted(() => {
    clearInterval(autoSlideInterval)
  })
})
