使用vue实现轮播

使用Vue实现轮播

使用Vue 2实现轮播

安装依赖：

npm install vue-awesome-swiper

引入Swiper组件：

import Vue from 'vue'
import VueAwesomeSwiper from 'vue-awesome-swiper'
import 'swiper/css/swiper.css'

Vue.use(VueAwesomeSwiper)

模板部分：

<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>

脚本部分：

export default {
  data() {
    return {
      slides: [
        { image: 'image1.jpg' },
        { image: 'image2.jpg' },
        { image: 'image3.jpg' }
      ],
      swiperOption: {
        pagination: {
          el: '.swiper-pagination',
          clickable: true
        },
        autoplay: {
          delay: 3000,
          disableOnInteraction: false
        },
        loop: true
      }
    }
  }
}

使用Vue 3实现轮播

安装依赖：

npm install swiper@8

组件实现：

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

<script>
import { onMounted } from 'vue'
import Swiper, { Pagination, Autoplay } from 'swiper'
import 'swiper/css'
import 'swiper/css/pagination'

export default {
  setup() {
    const slides = [
      { image: 'image1.jpg' },
      { image: 'image2.jpg' },
      { image: 'image3.jpg' }
    ]

    onMounted(() => {
      new Swiper('.swiper-container', {
        modules: [Pagination, Autoplay],
        pagination: {
          el: '.swiper-pagination',
          clickable: true
        },
        autoplay: {
          delay: 3000,
          disableOnInteraction: false
        },
        loop: true
      })
    })

    return { slides }
  }
}
</script>

自定义实现轮播

模板结构：

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

脚本逻辑：

export default {
  data() {
    return {
      currentIndex: 0,
      slides: [
        { image: 'image1.jpg' },
        { image: 'image2.jpg' },
        { image: 'image3.jpg' }
      ]
    }
  },
  methods: {
    prev() {
      this.currentIndex = (this.currentIndex - 1 + this.slides.length) % this.slides.length
    },
    next() {
      this.currentIndex = (this.currentIndex + 1) % this.slides.length
    }
  },
  mounted() {
    setInterval(this.next, 3000)
  }
}

样式部分：

.carousel {
  position: relative;
  overflow: hidden;
  width: 100%;
  height: 300px;
}

.slides {
  display: flex;
  transition: transform 0.5s ease;
}

.slide {
  flex: 0 0 100%;
}
