vue实现图片轮播效果

使用 Swiper 插件实现图片轮播

安装 Swiper 依赖：

npm install swiper

在 Vue 组件中引入 Swiper：

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

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

export default {
  data() {
    return {
      images: [
        'image1.jpg',
        'image2.jpg',
        'image3.jpg'
      ]
    }
  },
  mounted() {
    new Swiper('.swiper-container', {
      loop: true,
      autoplay: {
        delay: 3000,
        disableOnInteraction: false
      },
      pagination: {
        el: '.swiper-pagination',
        clickable: true
      },
      navigation: {
        nextEl: '.swiper-button-next',
        prevEl: '.swiper-button-prev'
      }
    })
  }
}
</script>

<style scoped>
.swiper-container {
  width: 100%;
  height: 300px;
}
.swiper-slide img {
  width: 100%;
  height: 100%;
  object-fit: cover;
}
</style>

纯 CSS 实现简单轮播

利用 CSS 动画实现基础轮播效果：

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

<script>
export default {
  data() {
    return {
      images: ['image1.jpg', 'image2.jpg', 'image3.jpg'],
      currentIndex: 0,
      interval: null
    }
  },
  mounted() {
    this.startAutoPlay()
  },
  beforeDestroy() {
    clearInterval(this.interval)
  },
  methods: {
    startAutoPlay() {
      this.interval = setInterval(() => {
        this.currentIndex = (this.currentIndex + 1) % this.images.length
      }, 3000)
    }
  }
}
</script>

<style scoped>
.carousel {
  position: relative;
  width: 100%;
  height: 300px;
  overflow: hidden;
}
.slides {
  display: flex;
  height: 100%;
  transition: transform 0.5s ease;
}
.slide {
  min-width: 100%;
}
.slide img {
  width: 100%;
  height: 100%;
  object-fit: cover;
}
.dots {
  position: absolute;
  bottom: 20px;
  left: 50%;
  transform: translateX(-50%);
  display: flex;
}
.dots span {
  width: 10px;
  height: 10px;
  margin: 0 5px;
  border-radius: 50%;
  background: #ccc;
  cursor: pointer;
}
.dots span.active {
  background: #333;
}
</style>

使用 Vue-Awesome-Swiper 组件

安装 vue-awesome-swiper：

npm install vue-awesome-swiper swiper@5.4.5

实现代码：

<template>
  <swiper :options="swiperOption" ref="mySwiper">
    <swiper-slide v-for="(item, index) in images" :key="index">
      <img :src="item" alt="">
    </swiper-slide>
    <div class="swiper-pagination" slot="pagination"></div>
    <div class="swiper-button-prev" slot="button-prev"></div>
    <div class="swiper-button-next" slot="button-next"></div>
  </swiper>
</template>

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

export default {
  components: {
    Swiper,
    SwiperSlide
  },
  data() {
    return {
      images: ['image1.jpg', 'image2.jpg', 'image3.jpg'],
      swiperOption: {
        loop: true,
        autoplay: {
          delay: 3000,
          disableOnInteraction: false
        },
        pagination: {
          el: '.swiper-pagination',
          clickable: true
        },
        navigation: {
          nextEl: '.swiper-button-next',
          prevEl: '.swiper-button-prev'
        }
      }
    }
  }
}
</script>

<style scoped>
.swiper-container {
  height: 300px;
}
.swiper-slide img {
  width: 100%;
  height: 100%;
  object-fit: cover;
}
</style>
