Vue 轮播实现方法

使用第三方库（推荐）

安装 swiper 或 vue-awesome-swiper 库，快速实现功能丰富的轮播效果。

以 vue-awesome-swiper 为例：

npm install swiper vue-awesome-swiper

组件代码示例：

<template>
  <swiper :options="swiperOption">
    <swiper-slide v-for="(slide, index) in slides" :key="index">
      <img :src="slide.image" alt="">
    </swiper-slide>
    <div class="swiper-pagination" slot="pagination"></div>
  </swiper>
</template>

<script>
import { Swiper, SwiperSlide } from 'vue-awesome-swiper'
import 'swiper/css/swiper.css'

export default {
  components: { Swiper, SwiperSlide },
  data() {
    return {
      slides: [
        { image: 'image1.jpg' },
        { image: 'image2.jpg' }
      ],
      swiperOption: {
        pagination: { el: '.swiper-pagination' },
        loop: true,
        autoplay: { delay: 3000 }
      }
    }
  }
}
</script>

原生实现

通过 Vue 的响应式数据和过渡效果实现基础轮播。

模板部分：

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

脚本部分：

<script>
export default {
  data() {
    return {
      slides: [
        { image: 'image1.jpg' },
        { image: 'image2.jpg' }
      ],
      currentIndex: 0,
      timer: null
    }
  },
  methods: {
    next() {
      this.currentIndex = (this.currentIndex + 1) % this.slides.length
    },
    prev() {
      this.currentIndex = (this.currentIndex - 1 + this.slides.length) % this.slides.length
    },
    startAutoPlay() {
      this.timer = setInterval(this.next, 3000)
    }
  },
  mounted() {
    this.startAutoPlay()
  },
  beforeDestroy() {
    clearInterval(this.timer)
  }
}
</script>

样式部分：

vue轮播实现

.slide-enter-active, .slide-leave-active {
  transition: opacity 0.5s;
}
.slide-enter, .slide-leave-to {
  opacity: 0;
}
.slides-container {
  position: relative;
  height: 300px;
}
.slide {
  position: absolute;
  width: 100%;
}
