Vue 走马灯实现方法

使用第三方库（如 Swiper）

安装 Swiper 库：

npm install swiper

在 Vue 组件中引入并使用：

<template>
  <div class="swiper-container">
    <div class="swiper-wrapper">
      <div class="swiper-slide" v-for="(item, index) in items" :key="index">
        {{ item }}
      </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/swiper-bundle.css'

export default {
  data() {
    return {
      items: ['Slide 1', 'Slide 2', 'Slide 3']
    }
  },
  mounted() {
    new Swiper('.swiper-container', {
      loop: true,
      pagination: {
        el: '.swiper-pagination',
        clickable: true
      },
      navigation: {
        nextEl: '.swiper-button-next',
        prevEl: '.swiper-button-prev'
      }
    })
  }
}
</script>

<style>
.swiper-container {
  width: 100%;
  height: 300px;
}
</style>

使用 Element UI 的 Carousel 组件

安装 Element UI：

npm install element-ui

在 Vue 项目中使用：

<template>
  <el-carousel :interval="3000" type="card" height="200px">
    <el-carousel-item v-for="(item, index) in items" :key="index">
      <h3>{{ item }}</h3>
    </el-carousel-item>
  </el-carousel>
</template>

<script>
import { ElCarousel, ElCarouselItem } from 'element-ui'

export default {
  components: {
    ElCarousel,
    ElCarouselItem
  },
  data() {
    return {
      items: ['Slide 1', 'Slide 2', 'Slide 3']
    }
  }
}
</script>

<style>
.el-carousel__item h3 {
  color: #475669;
  font-size: 18px;
  line-height: 200px;
  margin: 0;
  text-align: center;
}
</style>

自定义实现走马灯效果

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

<script>
export default {
  data() {
    return {
      items: ['Slide 1', 'Slide 2', 'Slide 3'],
      currentIndex: 0,
      timer: null
    }
  },
  methods: {
    prev() {
      this.currentIndex = (this.currentIndex - 1 + this.items.length) % this.items.length
    },
    next() {
      this.currentIndex = (this.currentIndex + 1) % this.items.length
    },
    startAutoPlay() {
      this.timer = setInterval(this.next, 3000)
    },
    stopAutoPlay() {
      clearInterval(this.timer)
    }
  },
  mounted() {
    this.startAutoPlay()
  },
  beforeDestroy() {
    this.stopAutoPlay()
  }
}
</script>

<style>
.carousel {
  width: 100%;
  overflow: hidden;
  position: relative;
}
.slides {
  display: flex;
  transition: transform 0.5s ease;
}
.slide {
  flex: 0 0 100%;
  height: 200px;
  display: flex;
  justify-content: center;
  align-items: center;
  font-size: 24px;
}
</style>
