Vue 实现 Banner 轮播

使用 Vue 实现 Banner 轮播可以通过原生开发或借助第三方库（如 Swiper）完成。以下是两种常见实现方式：

原生实现 Banner 轮播

创建一个基础的轮播组件，通过 Vue 的响应式数据和动画控制实现轮播效果。

<template>
  <div class="banner-container">
    <div class="banner" :style="{ transform: `translateX(-${currentIndex * 100}%)` }">
      <div class="banner-item" v-for="(item, index) in banners" :key="index">
        <img :src="item.image" :alt="item.title">
      </div>
    </div>
    <div class="dots">
      <span 
        v-for="(item, index) in banners" 
        :key="index" 
        :class="{ active: currentIndex === index }"
        @click="currentIndex = index"
      ></span>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      banners: [
        { image: 'image1.jpg', title: 'Banner 1' },
        { image: 'image2.jpg', title: 'Banner 2' },
        { image: 'image3.jpg', title: 'Banner 3' }
      ],
      currentIndex: 0,
      timer: null
    };
  },
  mounted() {
    this.startAutoPlay();
  },
  methods: {
    startAutoPlay() {
      this.timer = setInterval(() => {
        this.currentIndex = (this.currentIndex + 1) % this.banners.length;
      }, 3000);
    },
    stopAutoPlay() {
      clearInterval(this.timer);
    }
  },
  beforeDestroy() {
    this.stopAutoPlay();
  }
};
</script>

<style>
.banner-container {
  position: relative;
  overflow: hidden;
  width: 100%;
  height: 300px;
}
.banner {
  display: flex;
  transition: transform 0.5s ease;
}
.banner-item {
  flex: 0 0 100%;
}
.banner-item img {
  width: 100%;
  height: 100%;
  object-fit: cover;
}
.dots {
  position: absolute;
  bottom: 20px;
  left: 50%;
  transform: translateX(-50%);
}
.dots span {
  display: inline-block;
  width: 10px;
  height: 10px;
  margin: 0 5px;
  border-radius: 50%;
  background-color: #ccc;
  cursor: pointer;
}
.dots span.active {
  background-color: #333;
}
</style>

使用 Swiper 实现 Banner 轮播

Swiper 是一个功能强大的轮播库，支持触摸滑动、自动播放、分页器等特性。

安装 Swiper 依赖：
```
npm install swiper
```

在 Vue 组件中使用 Swiper：


<template>
<div class="swiper-container">
 <div class="swiper-wrapper">
   <div class="swiper-slide" v-for="(item, index) in banners" :key="index">
     <img :src="item.image" :alt="item.title">
   </div>
 </div>
 <div class="swiper-pagination"></div>
</div>
</template>

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

export default { data() { return { banners: [ { image: 'image1.jpg', title: 'Banner 1' }, { image: 'image2.jpg', title: 'Banner 2' }, { image: 'image3.jpg', title: 'Banner 3' } ] }; }, mounted() { new Swiper('.swiper-container', { loop: true, autoplay: { delay: 3000, }, pagination: { el: '.swiper-pagination', clickable: true, }, }); } };

.swiper-container { width: 100%; height: 300px; } .swiper-slide img { width: 100%; height: 100%; object-fit: cover; } ```
