为什么封装？

迎合es6模块化开发思想
注册为全局组件，可以更好地复用，需要用到的地方，直接使用标签即可

静态结构后面再进行更改

<script lang="ts" setup name="XtxCarousel">
defineProps()
</script>
<template>
  <div class="xtx-carousel">
    <ul class="carousel-body">
      <li class="carousel-item fade">
        <RouterLink to="/">
          <img
            src="/file/imgs/upload/202211/13/wgllur3sDDD.jpg"
            alt=""
          />
        </RouterLink>
      </li>
      <li class="carousel-item">
        <RouterLink to="/">
          <img
            src="/file/imgs/upload/202211/13/wgllur3sddd.jpg"
            alt=""
          />
        </RouterLink>
      </li>
      <li class="carousel-item">
        <RouterLink to="/">
          <img

      ><i class="iconfont icon-angle-right"></i
    ></a>
    <div class="carousel-indicator">
      <span class="active"></span>
      <span></span>
      <span></span>
      <span></span>
      <span></span>
    </div>
  </div>
</template>

<style scoped lang="less">

      }
    }
  }
  &:hover {
    .carousel-btn {

    }
  }
}
</style>

请求数据都存放在pinia里面

import { defineStore } from 'pinia'
import request from '@/utils/request'
import { BannerItem, IapiRes } from '@/types/data'

export default defineStore('home', {
  persist: {
    enabled: true
  },
  
  state() {
    return {
      bannerList: [] as BannerItem[]
    }
  },
  actions: {
    // 拿轮播图数据
    async getBannerList() {
      const res = await request.get<IApiRes<BannerItem[]>>('/home/banner')
      console.log('拿轮播图数据', res)
      this.bannerList = res.data.result
    }
  }
})

类型检测

// 所有的接口的通用类型
export interface IApiRes<T> {
  msg: string,
  result: T
}

// 轮播图数据中的项
export type BannerItem = {
  id: string;
  imgUrl: string;
  hrefUrl: string;
  type: string;
}

页面级组件

<script lang="ts" setup>
import useStore from '@/store';
const { home } = useStore()
// 发请求
home.getBannerList()

</script>
<template>
  <div class="home-banner">
    <!-- 轮播图子组件 -->
    <XtxCarousel :slides="home.bannerList" :autoPlay="true" :duration="1000"/>
  </div>
</template>

<style scoped lang="less">
.home-banner {
  width: 1240px;
  height: 450px;
  position: absolute;
  left: 0;
  top: 0;
  z-index: 98;
  background-color: #ccc;
}
/deep/ .xtx-carousel .carousel-btn.prev {
  left: 270px !important;
}
/deep/ .xtx-carousel .carousel-indicator {
  padding-left: 250px;
}
</style>

全局组件

<script lang="ts" setup name="XtxCarousel">
import { BannerItem } from '@/types/data'
import { onBeforeUnmount, onMounted, ref } from 'Vue';
// 定义props
const { slides, autoPlay, duration } = defineProps<{
  slides: BannerItem[], 
  autoPlay?: boolean, // 是否开启自动播放
  duration?: number // 自动播放的间隔时间
}>()

// 当前哪个图片选中 高亮
const active = ref(1)

// 点击右侧箭头++
const hNext = () => {
  active.value++
  if(active.value === slides.length){
    active.value = 0
  }
}

// 点击左侧箭头--
const hPrev = () => {
  active.value--
  if(active.value < 0){
    active.value = slides.length - 1
  }
}

// 如果开启了自动播放，则每隔duration去播放下一张： hNext()
onMounted(() => {
  start()
})

onBeforeUnmount(() => {
  stop()
})

let timer = -1

// 鼠标离开要继续播放
const start = () => {
  if(autoPlay) {
    timer = window.setInterval(() => {
      hNext()
    }, duration)
  }
}

// 鼠标hover要暂停播放
const stop = () => {
  clearInterval(timer)
}
</script>
