Vue3使用触摸滑动插件（Swiper）_vue3 swiper

Vue2使用触摸滑动插件（Swiper）

参考文档：

• Swiper官方

• Swiper API

• Swiper Vue

• Swiper Demos

本文使用版本：Swiper@11.0.5

安装插件：pnpm i swiper

本文基于Swiper插件进行封装，主要实现两种形式的轮播图展示：

• 首页轮播图切换展示（type: banner）

• 走马灯轮播图滚动展示（type: carousel）

• 信息展播模式（type: broadcast）

可自定义设置以下属性：

• 轮播图片数组（images），类型：Array<{title: string, link?: string, src: string}>，默认 []

• 图片宽度（width），类型：number | string，默认 '100%'

• 图片高度（height），类型：number | string，默认 '100vh'

• banner轮播图模式 | carousel走马灯模式（type），类型：'banner'|'carouse'|'broadcast'，默认 'banner'

• 是否显示导航（navigation），类型：boolean，默认 true

• 自动切换的时间间隔（type: banner时生效）（delay），单位ms，类型：number，默认 3000

• 是否可以鼠标拖动（swipe），类型：boolean，默认 true

• 预加载时的loading颜色（preloaderColor），类型：'theme'|'white'|'black'，默认 'theme'，可选 theme(主题色) | white | black

效果如下图：在线预览

首页轮播图 type: banner

走马灯 type: carousel 

信息展播 type: broadcast

①创建触摸滑动组件Swiper.vue：

<script setup lang="ts">
import { Swiper, SwiperSlide } from 'swiper/vue'
import { Pagination, Navigation, Autoplay, EffectFade, Mousewheel } from 'swiper/modules'
import 'swiper/css'
import 'swiper/css/navigation'
import 'swiper/css/pagination'
import 'swiper/css/effect-fade'
import { ref, computed } from 'vue'
interface Image {
  title: string // 图片名称
  link?: string // 图片跳转链接
  src: string // 图片地址
}
interface Props {
  images: Image[] // 轮播图片数组
  width?: number|string // 图片宽度
  height?: number|string // 图片高度
  type?: 'banner'|'carousel'|'broadcast' // banner轮播图模式 | carousel走马灯模式
  navigation?: boolean // 是否显示导航
  delay?: number // 自动切换的时间间隔（type: banner时生效），单位ms
  swipe?: boolean // 是否可以鼠标拖动
  preloaderColor?: 'theme'|'white'|'black' // 预加载时的loading颜色
}
const props = withDefaults(defineProps<Props>(), {
  images: () => [],
  width: '100%',
  height: '100vh',
  type: 'banner', // 可选 banner | carousel
  navigation: true,
  delay: 3000,
  swipe: true,
  preloaderColor: 'theme' // 可选 theme white black
})
const imgWidth = computed(() => {
  if (typeof props.width === 'number') {
    return props.width + 'px'
  } else {
    return props.width
  }
})
const imgHeight = computed(() => {
  if (typeof props.height === 'number') {
    return props.height + 'px'
  } else {
    return props.height
  }
})
const modulesBanner = ref([Navigation, Pagination, Autoplay, EffectFade])
const autoplayBanner = ref({
  delay: props.delay, 
  disableOnInteraction: false, // 用户操作swiper之后，是否禁止autoplay。默认为true：停止。
  pauseOnMouseEnter: true // 鼠标置于swiper时暂停自动切换，鼠标离开时恢复自动切换，默认false
})
 
const modulesCarousel = ref([Autoplay])
const autoplayCarousel = ref<object|boolean>({
  delay: 0,
  disableOnInteraction: false
})
const modulesBroadcast = ref([Navigation, Pagination, Mousewheel])
const emits = defineEmits(['swiper', 'change'])
function onSwiper (swiper: any) {
  // console.log(swiper)
  emits('swiper', swiper)
  if (props.type === 'carousel') {
    swiper.el.onmouseenter = () => { // 移入暂停
      swiper.autoplay.stop()
    }
    swiper.el.onmouseleave = () => { // 移出启动
      swiper.autoplay.start()
    }
  }
}
</script>

  width: 12px;
  height: 12px;
}
.swiper-lazy-preloader-theme {
  --swiper-preloader-color: @themeColor;
}
</style>

②在要使用的页面引入：

<script setup lang="ts">
import Swiper from './Swiper.vue'
import pkg from '/package.json'
import { ref, shallowReactive, onBeforeMount } from 'vue'
 
const images = ref<any[]>([])
function loadImages () {
  for (let i = 1; i <= 10; i++) {
    images.value.push({
      title: `image-${i}`,
      link: `https://cdn.jsdelivr.net/gh/themusecatcher/resources@0.0.5/${i}.jpg`,
      src: `https://cdn.jsdelivr.net/gh/themusecatcher/resources@0.0.5/${i}.jpg`
    })
  }
}
onBeforeMount(() => { // 组件已完成响应式状态设置，但未创建DOM节点
  loadImages()
})
function onChange () {
  console.log('slider change')
}
const navigation = shallowReactive<{[key: string]: any}>({})
function onSwiper (swiper: any) {
  navigation.prevEl = swiper.navigation.prevEl
  navigation.prevEl.style.display = 'none'
  navigation.nextEl = swiper.navigation.nextEl
  navigation.nextEl.style.display = 'none'
}
function onPrev () {
  navigation.prevEl.click()
}
function onNext () {
  navigation.nextEl.click()
}
</script>
