vue过渡实现轮播图

使用`<transition>`和`<transition-group>`

Vue的过渡系统可以通过<transition>或<transition-group>组件实现轮播效果。结合CSS过渡类名（如v-enter、v-leave-to）定义动画效果，通过动态绑定key或v-show控制轮播项的切换。

vue过渡实现轮播图

<template>
  <div class="carousel">
    <transition :name="transitionName" mode="out-in">
      <div :key="currentIndex" class="slide">
        <img :src="slides[currentIndex]" />
      </div>
    </transition>
    <button @click="prev">上一张</button>
    <button @click="next">下一张</button>
  </div>
</template>

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

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

自动轮播与暂停

通过setInterval实现自动轮播，结合clearInterval在鼠标悬停时暂停。

export default {
  mounted() {
    this.startAutoPlay();
  },
  methods: {
    startAutoPlay() {
      this.intervalId = setInterval(() => {
        this.next();
      }, 3000);
    },
    pauseAutoPlay() {
      clearInterval(this.intervalId);
    }
  }
};

使用第三方库

若需更复杂效果，可结合vue-awesome-swiper或swiper.js等库，它们内置了丰富的过渡效果和交互功能。

npm install swiper vue-awesome-swiper

<template>
  <swiper :options="swiperOptions">
    <swiper-slide v-for="(slide, index) in slides" :key="index">
      <img :src="slide" />
    </swiper-slide>
  </swiper>
</template>

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

export default {
  components: { Swiper, SwiperSlide },
  data() {
    return {
      slides: ['image1.jpg', 'image2.jpg', 'image3.jpg'],
      swiperOptions: {
        autoplay: { delay: 3000 },
        effect: 'fade'
      }
    };
  }
};
</script>
