本地实现vue轮播

使用Swiper实现Vue轮播

Swiper是一个流行的开源轮播库，支持Vue3/Vue2。安装依赖：

npm install swiper@8

Vue3组件示例：

<template>
  <swiper
    :modules="[Navigation, Pagination]"
    navigation
    pagination
    :loop="true"
  >
    <swiper-slide v-for="(slide, index) in slides" :key="index">
      <img :src="slide.image" />
    </swiper-slide>
  </swiper>
</template>

<script setup>
import { Swiper, SwiperSlide } from 'swiper/vue'
import { Navigation, Pagination } from 'swiper'
import 'swiper/css'
import 'swiper/css/navigation'
import 'swiper/css/pagination'

const slides = [
  { image: '/image1.jpg' },
  { image: '/image2.jpg' }
]
</script>

纯CSS实现简易轮播

利用CSS动画实现基础轮播效果：

<template>
  <div class="carousel">
    <div class="slides" :style="slideStyle">
      <div v-for="(item, index) in items" :key="index" class="slide">
        {{ item.content }}
      </div>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      currentIndex: 0,
      items: [
        { content: 'Slide 1' },
        { content: 'Slide 2' }
      ]
    }
  },
  computed: {
    slideStyle() {
      return {
        transform: `translateX(-${this.currentIndex * 100}%)`
      }
    }
  }
}
</script>

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

使用Vue-Awesome-Swiper

Vue-Awesome-Swiper是Swiper的Vue封装版本：

npm install vue-awesome-swiper@4

Vue2实现代码：

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

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

export default {
  components: {
    swiper,
    swiperSlide
  },
  data() {
    return {
      slides: [
        { image: '/slide1.jpg' },
        { image: '/slide2.jpg' }
      ],
      swiperOption: {
        pagination: {
          el: '.swiper-pagination'
        },
        loop: true,
        autoplay: {
          delay: 3000
        }
      }
    }
  }
}
</script>

自定义Vue轮播组件

创建可复用的轮播组件：

<template>
  <div class="carousel-container">
    <button @click="prev">Prev</button>
    <div class="slide-wrapper">
      <transition-group name="slide">
        <div v-for="(item, index) in visibleItems" 
             :key="item.id" 
             class="slide-item">
          {{ item.content }}
        </div>
      </transition-group>
    </div>
    <button @click="next">Next</button>
  </div>
</template>

<script>
export default {
  props: {
    items: Array,
    visibleCount: {
      type: Number,
      default: 1
    }
  },
  data() {
    return {
      currentIndex: 0
    }
  },
  computed: {
    visibleItems() {
      return this.items.slice(
        this.currentIndex, 
        this.currentIndex + this.visibleCount
      )
    }
  },
  methods: {
    next() {
      this.currentIndex = Math.min(
        this.currentIndex + 1, 
        this.items.length - this.visibleCount
      )
    },
    prev() {
      this.currentIndex = Math.max(0, this.currentIndex - 1)
    }
  }
}
</script>

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