vue如何实现全屏轮播

Vue实现全屏轮播的方法

使用第三方库（如swiper.js）

安装swiper.js库：

npm install swiper

在Vue组件中引入并配置：

<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 Swiper from 'swiper'
import 'swiper/swiper-bundle.css'

export default {
  data() {
    return {
      slides: [
        { image: 'image1.jpg' },
        { image: 'image2.jpg' },
        { image: 'image3.jpg' }
      ]
    }
  },
  mounted() {
    new Swiper('.swiper-container', {
      direction: 'vertical',
      loop: true,
      pagination: {
        el: '.swiper-pagination',
        clickable: true
      },
      autoplay: {
        delay: 3000
      }
    })
  }
}
</script>

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

纯Vue实现

通过Vue的过渡效果和定时器实现：

<template>
  <div class="fullscreen-carousel">
    <transition :name="transitionName">
      <div 
        class="slide"
        v-for="(slide, index) in slides"
        v-show="currentIndex === index"
        :key="index"
      >
        <img :src="slide.image" alt="">
      </div>
    </transition>
    <div class="indicators">
      <span 
        v-for="(slide, index) in slides"
        :key="index"
        :class="{ active: currentIndex === index }"
        @click="goToSlide(index)"
      ></span>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      slides: [
        { image: 'image1.jpg' },
        { image: 'image2.jpg' },
        { image: 'image3.jpg' }
      ],
      currentIndex: 0,
      transitionName: 'slide-left',
      timer: null
    }
  },
  methods: {
    goToSlide(index) {
      this.transitionName = index > this.currentIndex ? 'slide-left' : 'slide-right'
      this.currentIndex = index
      this.resetTimer()
    },
    nextSlide() {
      this.transitionName = 'slide-left'
      this.currentIndex = (this.currentIndex + 1) % this.slides.length
    },
    resetTimer() {
      clearInterval(this.timer)
      this.startTimer()
    },
    startTimer() {
      this.timer = setInterval(this.nextSlide, 3000)
    }
  },
  mounted() {
    this.startTimer()
  },
  beforeDestroy() {
    clearInterval(this.timer)
  }
}
</script>

<style scoped>
.fullscreen-carousel {
  position: relative;
  width: 100%;
  height: 100vh;
  overflow: hidden;
}
.slide {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
}
.slide img {
  width: 100%;
  height: 100%;
  object-fit: cover;
}
.indicators {
  position: absolute;
  bottom: 20px;
  left: 50%;
  transform: translateX(-50%);
  display: flex;
}
.indicators span {
  width: 10px;
  height: 10px;
  margin: 0 5px;
  border-radius: 50%;
  background: rgba(255,255,255,0.5);
  cursor: pointer;
}
.indicators span.active {
  background: white;
}
.slide-left-enter-active,
.slide-left-leave-active,
.slide-right-enter-active,
.slide-right-leave-active {
  transition: all 1s ease;
}
.slide-left-enter {
  transform: translateX(100%);
}
.slide-left-leave-to {
  transform: translateX(-100%);
}
.slide-right-enter {
  transform: translateX(-100%);
}
.slide-right-leave-to {
  transform: translateX(100%);
}
</style>

关键点说明

确保轮播容器设置为全屏高度：

.container {
  height: 100vh;
}

图片适应全屏：

img {
  object-fit: cover;
  width: 100%;
  height: 100%;
}

实现平滑过渡效果：

transition: all 0.5s ease;

自动轮播逻辑：

setInterval(() => {
  this.currentIndex = (this.currentIndex + 1) % this.slides.length
}, 3000)

注意事项

1. 移动端适配需要添加viewport meta标签
2. 图片预加载可以提升用户体验
3. 离开页面时清除定时器防止内存泄漏
4. 考虑添加触摸滑动支持
5. 可以添加键盘事件监听左右箭头切换
