Vue 实现轮播的方法

使用第三方库（如 Swiper）

Swiper 是一个流行的轮播库，支持 Vue 集成。安装 Swiper 后，可以通过配置实现轮播效果。

npm install swiper vue-awesome-swiper

在 Vue 组件中引入并配置 Swiper：

<template>
  <swiper :options="swiperOptions">
    <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/swiper-bundle.css'

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

自定义轮播组件

通过 Vue 的动态组件和定时器实现简单的轮播功能。

<template>
  <div class="carousel">
    <div class="slides">
      <div v-for="(slide, index) in slides" 
           :key="index" 
           :class="{ active: currentIndex === index }">
        <img :src="slide.image" alt="">
      </div>
    </div>
    <button @click="prev">Prev</button>
    <button @click="next">Next</button>
  </div>
</template>

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

<style>
.slides div {
  display: none;
}
.slides div.active {
  display: block;
}
</style>

使用 Vue 过渡动画

结合 Vue 的 <transition> 组件实现平滑的轮播切换效果。

<template>
  <div class="carousel">
    <transition :name="transitionName">
      <div :key="currentIndex">
        <img :src="slides[currentIndex].image" alt="">
      </div>
    </transition>
    <button @click="prev">Prev</button>
    <button @click="next">Next</button>
  </div>
</template>

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

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