vue实现轮播页

使用 Swiper 插件实现轮播

Swiper 是一个流行的轮播组件库，支持 Vue 集成。安装 Swiper 及相关依赖：

npm install swiper vue-awesome-swiper

在 Vue 组件中引入并使用：

<template>
  <swiper :options="swiperOptions">
    <swiper-slide v-for="(item, index) in slides" :key="index">
      <img :src="item.image" alt="Slide">
    </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: 'https://via.placeholder.com/800x400' },
        { image: 'https://via.placeholder.com/800x400' }
      ],
      swiperOptions: {
        pagination: { el: '.swiper-pagination' },
        loop: true,
        autoplay: { delay: 3000 }
      }
    }
  }
}
</script>

纯 CSS 实现简单轮播

通过 CSS 动画和 overflow: hidden 实现基础轮播效果：

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

<script>
export default {
  data() {
    return {
      currentIndex: 0,
      slides: [
        { image: 'https://via.placeholder.com/800x400' },
        { image: 'https://via.placeholder.com/800x400' }
      ],
      interval: null
    }
  },
  mounted() {
    this.interval = setInterval(() => {
      this.currentIndex = (this.currentIndex + 1) % this.slides.length
    }, 3000)
  },
  beforeDestroy() {
    clearInterval(this.interval)
  }
}
</script>

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

使用 Vue Carousel 组件库

vue-carousel 是专为 Vue 设计的轮播库：

npm install vue-carousel

实现代码示例：

<template>
  <carousel :perPage="1" :autoplay="true" :loop="true">
    <slide v-for="(slide, index) in slides" :key="index">
      <img :src="slide.image" alt="Slide">
    </slide>
  </carousel>
</template>

<script>
import { Carousel, Slide } from 'vue-carousel'

export default {
  components: { Carousel, Slide },
  data() {
    return {
      slides: [
        { image: 'https://via.placeholder.com/800x400' },
        { image: 'https://via.placeholder.com/800x400' }
      ]
    }
  }
}
</script>
