Vue 幻灯片实现方法

使用第三方库（推荐）

Vue-Awesome-Swiper 是一个基于 Swiper 的 Vue 轮播组件，功能强大且易于使用。

安装依赖：

npm install swiper vue-awesome-swiper --save

基本用法：

<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>

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

export default {
  components: {
    Swiper,
    SwiperSlide
  },
  data() {
    return {
      slides: [
        { image: 'image1.jpg' },
        { image: 'image2.jpg' },
        { image: 'image3.jpg' }
      ],
      swiperOption: {
        pagination: {
          el: '.swiper-pagination'
        },
        loop: true,
        autoplay: {
          delay: 3000
        }
      }
    }
  }
}
</script>

自定义实现

对于简单需求，可以手动实现基本幻灯片功能。

基础实现代码：

<template>
  <div class="slider">
    <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">Prev</button>
    <button @click="next">Next</button>
  </div>
</template>

<script>
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
    }
  }
}
</script>

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

动画效果增强

使用 Vue 的过渡系统添加动画效果。

<template>
  <transition name="fade" mode="out-in">
    <img :key="currentIndex" :src="currentSlide.image" alt="">
  </transition>
  <button @click="prev">Prev</button>
  <button @click="next">Next</button>
</template>

<script>
export default {
  data() {
    return {
      currentIndex: 0,
      slides: [
        { image: 'image1.jpg' },
        { image: 'image2.jpg' },
        { image: 'image3.jpg' }
      ]
    }
  },
  computed: {
    currentSlide() {
      return this.slides[this.currentIndex]
    }
  },
  methods: {
    prev() {
      this.currentIndex = (this.currentIndex - 1 + this.slides.length) % this.slides.length
    },
    next() {
      this.currentIndex = (this.currentIndex + 1) % this.slides.length
    }
  }
}
</script>

<style>
.fade-enter-active, .fade-leave-active {
  transition: opacity 0.5s;
}
.fade-enter, .fade-leave-to {
  opacity: 0;
}
</style>

响应式设计

确保幻灯片在不同屏幕尺寸下正常显示。

.slider {
  max-width: 100%;
  margin: 0 auto;
}

.slide img {
  width: 100%;
  height: auto;
}

@media (max-width: 768px) {
  .slider {
    max-width: 90%;
  }
}
