Vue Banner 的实现方法

在 Vue 中实现 Banner 功能通常涉及轮播图或广告横幅的展示。以下是几种常见的实现方式：

使用第三方库（如 Swiper）

安装 Swiper 库：

npm install swiper

在 Vue 组件中引入并使用：

<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 class="swiper-button-next"></div>
    <div class="swiper-button-prev"></div>
  </div>
</template>

<script>
import Swiper from 'swiper'
import 'swiper/css/swiper.min.css'

export default {
  data() {
    return {
      banners: [
        { image: 'path/to/image1.jpg', title: 'Banner 1' },
        { image: 'path/to/image2.jpg', title: 'Banner 2' }
      ]
    }
  },
  mounted() {
    new Swiper('.swiper-container', {
      loop: true,
      pagination: {
        el: '.swiper-pagination',
        clickable: true
      },
      navigation: {
        nextEl: '.swiper-button-next',
        prevEl: '.swiper-button-prev'
      }
    })
  }
}
</script>

使用 Vue 原生实现

通过 Vue 的过渡和动画特性实现简单轮播：

<template>
  <div class="banner-container">
    <transition-group name="fade" tag="div" class="banner-wrapper">
      <div v-for="(item, index) in banners" 
           :key="index" 
           v-show="currentIndex === index"
           class="banner-item">
        <img :src="item.image" :alt="item.title">
      </div>
    </transition-group>
    <div class="banner-dots">
      <span v-for="(item, index) in banners" 
            :key="index" 
            @click="currentIndex = index"
            :class="{ active: currentIndex === index }">
      </span>
    </div>
  </div>
</template>

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

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

使用 Vue 组件库

如使用 Element UI 的 Carousel 组件：

<template>
  <el-carousel :interval="3000" arrow="always">
    <el-carousel-item v-for="(item, index) in banners" :key="index">
      <img :src="item.image" :alt="item.title">
    </el-carousel-item>
  </el-carousel>
</template>

<script>
export default {
  data() {
    return {
      banners: [
        { image: 'path/to/image1.jpg', title: 'Banner 1' },
        { image: 'path/to/image2.jpg', title: 'Banner 2' }
      ]
    }
  }
}
</script>
