使用 Vue 实现轮播

使用原生 Vue 实现

创建一个基础的轮播组件，通过动态绑定 v-for 和 v-show 控制显示当前幻灯片。

<template>
  <div class="carousel">
    <div class="slides">
      <div 
        v-for="(slide, index) in slides" 
        :key="index"
        class="slide"
        :class="{ active: currentIndex === index }"
      >
        {{ slide }}
      </div>
    </div>
    <button @click="prev">Previous</button>
    <button @click="next">Next</button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      slides: ['Slide 1', 'Slide 2', 'Slide 3'],
      currentIndex: 0,
    };
  },
  methods: {
    prev() {
      this.currentIndex = (this.currentIndex - 1 + this.slides.length) % this.slides.length;
    },
    next() {
      this.currentIndex = (this.currentIndex + 1) % this.slides.length;
    },
  },
};
</script>

<style>
.slide {
  display: none;
}
.slide.active {
  display: block;
}
</style>

使用第三方库 Vue-Awesome-Swiper

Vue-Awesome-Swiper 是基于 Swiper 的 Vue 轮播组件，功能丰富且易于集成。

安装依赖：

npm install swiper vue-awesome-swiper

示例代码：

<template>
  <swiper :options="swiperOptions">
    <swiper-slide v-for="(slide, index) in slides" :key="index">
      {{ slide }}
    </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: ['Slide 1', 'Slide 2', 'Slide 3'],
      swiperOptions: {
        pagination: {
          el: '.swiper-pagination',
        },
        loop: true,
      },
    };
  },
};
</script>

使用 Vue 过渡效果

通过 Vue 的 <transition> 或 <transition-group> 实现平滑的轮播过渡效果。

<template>
  <div class="carousel">
    <transition-group name="fade" tag="div" class="slides">
      <div 
        v-for="(slide, index) in slides" 
        :key="index"
        class="slide"
        v-show="currentIndex === index"
      >
        {{ slide }}
      </div>
    </transition-group>
    <button @click="prev">Previous</button>
    <button @click="next">Next</button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      slides: ['Slide 1', 'Slide 2', 'Slide 3'],
      currentIndex: 0,
    };
  },
  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>

自动轮播

通过 setInterval 实现自动轮播功能，注意在组件销毁时清除定时器。

<template>
  <div class="carousel">
    <div class="slides">
      <div 
        v-for="(slide, index) in slides" 
        :key="index"
        class="slide"
        :class="{ active: currentIndex === index }"
      >
        {{ slide }}
      </div>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      slides: ['Slide 1', 'Slide 2', 'Slide 3'],
      currentIndex: 0,
      interval: null,
    };
  },
  mounted() {
    this.interval = setInterval(() => {
      this.currentIndex = (this.currentIndex + 1) % this.slides.length;
    }, 3000);
  },
  beforeDestroy() {
    clearInterval(this.interval);
  },
};
</script>

以上方法涵盖了从基础实现到高级功能的轮播效果，可以根据需求选择适合的方案。
