Vue实现左右轮播的方法

使用Swiper.js实现左右轮播

安装Swiper.js库：

npm install swiper

在Vue组件中使用：

<template>
  <div class="swiper-container">
    <div class="swiper-wrapper">
      <div class="swiper-slide" v-for="(item, index) in slides" :key="index">
        <img :src="item.image" alt="">
      </div>
    </div>
    <div class="swiper-button-prev"></div>
    <div class="swiper-button-next"></div>
  </div>
</template>

<script>
import Swiper from 'swiper'
import 'swiper/css/swiper.min.css'

export default {
  data() {
    return {
      slides: [
        { image: 'image1.jpg' },
        { image: 'image2.jpg' },
        { image: 'image3.jpg' }
      ]
    }
  },
  mounted() {
    new Swiper('.swiper-container', {
      navigation: {
        nextEl: '.swiper-button-next',
        prevEl: '.swiper-button-prev',
      },
      loop: true,
    })
  }
}
</script>

纯CSS实现基础轮播

使用CSS动画和Vue控制：

<template>
  <div class="carousel">
    <div class="slides" :style="{ transform: `translateX(${-currentIndex * 100}%)` }">
      <div class="slide" v-for="(item, index) in slides" :key="index">
        <img :src="item.image" alt="">
      </div>
    </div>
    <button @click="prev">Prev</button>
    <button @click="next">Next</button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      currentIndex: 0,
      slides: [
        { image: 'image1.jpg' },
        { image: 'image2.jpg' },
        { image: 'image3.jpg' }
      ]
    }
  },
  methods: {
    prev() {
      this.currentIndex = (this.currentIndex - 1 + this.slides.length) % this.slides.length
    },
    next() {
      this.currentIndex = (this.currentIndex + 1) % this.slides.length
    }
  }
}
</script>

<style>
.carousel {
  overflow: hidden;
  position: relative;
  width: 100%;
  height: 300px;
}
.slides {
  display: flex;
  transition: transform 0.5s ease;
}
.slide {
  flex: 0 0 100%;
}
</style>

使用Vue过渡动画

添加更平滑的过渡效果：

<template>
  <div class="carousel">
    <transition-group name="slide" tag="div" class="slides">
      <div class="slide" v-for="(item, index) in slides" :key="index" v-show="index === currentIndex">
        <img :src="item.image" alt="">
      </div>
    </transition-group>
    <button @click="prev">Prev</button>
    <button @click="next">Next</button>
  </div>
</template>

<style>
.slide-enter-active, .slide-leave-active {
  transition: all 0.5s ease;
}
.slide-enter {
  transform: translateX(100%);
}
.slide-leave-to {
  transform: translateX(-100%);
}
</style>

自动轮播功能实现

添加自动轮播逻辑：

export default {
  data() {
    return {
      currentIndex: 0,
      slides: [...],
      interval: null
    }
  },
  methods: {
    startAutoPlay() {
      this.interval = setInterval(() => {
        this.next()
      }, 3000)
    },
    stopAutoPlay() {
      clearInterval(this.interval)
    }
  },
  mounted() {
    this.startAutoPlay()
  },
  beforeDestroy() {
    this.stopAutoPlay()
  }
}
