使用Swiper实现轮播组件

Swiper是一个流行的开源轮播库，支持Vue集成。安装Swiper和Vue相关依赖：

npm install swiper vue-awesome-swiper

引入Swiper组件和样式：

import { Swiper, SwiperSlide } from 'swiper/vue'
import 'swiper/css'

模板中使用Swiper：

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

配置Swiper选项：

data() {
  return {
    swiperOptions: {
      loop: true,
      autoplay: {
        delay: 3000,
        disableOnInteraction: false
      },
      pagination: {
        el: '.swiper-pagination',
        clickable: true
      }
    },
    slides: [
      { image: 'image1.jpg' },
      { image: 'image2.jpg' }
    ]
  }
}

自定义Vue轮播组件

创建基础轮播组件结构：

<div class="carousel">
  <div class="slides" :style="slideStyle">
    <div v-for="(slide, index) in slides" 
         :key="index" 
         class="slide">
      <img :src="slide.image" alt="">
    </div>
  </div>
  <button @click="prev">Prev</button>
  <button @click="next">Next</button>
</div>

实现轮播逻辑：

data() {
  return {
    currentIndex: 0,
    slides: [
      { image: 'image1.jpg' },
      { image: 'image2.jpg' }
    ],
    transitionSpeed: 500
  }
},
computed: {
  slideStyle() {
    return {
      transform: `translateX(-${this.currentIndex * 100}%)`,
      transition: `transform ${this.transitionSpeed}ms ease`
    }
  }
},
methods: {
  next() {
    this.currentIndex = (this.currentIndex + 1) % this.slides.length
  },
  prev() {
    this.currentIndex = (this.currentIndex - 1 + this.slides.length) % this.slides.length
  }
}

添加自动轮播功能：

mounted() {
  this.startAutoPlay()
},
methods: {
  startAutoPlay() {
    this.interval = setInterval(() => {
      this.next()
    }, 3000)
  },
  stopAutoPlay() {
    clearInterval(this.interval)
  }
}

添加过渡动画效果

使用Vue的transition组件实现平滑过渡：

<transition-group 
  name="slide" 
  tag="div" 
  class="slides">
  <div v-for="(slide, index) in slides" 
       v-show="index === currentIndex"
       :key="index" 
       class="slide">
    <img :src="slide.image" alt="">
  </div>
</transition-group>

添加CSS过渡样式：

.slide-enter-active, .slide-leave-active {
  transition: opacity 0.5s ease;
}
.slide-enter, .slide-leave-to {
  opacity: 0;
}

响应式轮播实现

监听窗口大小变化调整轮播参数：

data() {
  return {
    slidesPerView: 3
  }
},
mounted() {
  window.addEventListener('resize', this.handleResize)
  this.handleResize()
},
beforeDestroy() {
  window.removeEventListener('resize', this.handleResize)
},
methods: {
  handleResize() {
    if (window.innerWidth < 768) {
      this.slidesPerView = 1
    } else if (window.innerWidth < 1024) {
      this.slidesPerView = 2
    } else {
      this.slidesPerView = 3
    }
  }
}

添加指示器和控制按钮

实现指示器逻辑：

<div class="indicators">
  <span 
    v-for="(item, index) in slides" 
    :key="index" 
    :class="{ active: currentIndex === index }"
    @click="goTo(index)">
  </span>
</div>

添加导航方法：

methods: {
  goTo(index) {
    this.currentIndex = index
  }
}

样式化指示器：

.indicators span {
  display: inline-block;
  width: 10px;
  height: 10px;
  margin: 0 5px;
  border-radius: 50%;
  background: #ccc;
  cursor: pointer;
}
.indicators span.active {
  background: #333;
}
