实现功能: 点击按钮切换，每页5个商品，当最后商品不满一页时 切换剩余的商品，如果切换到第一个则禁用左边按钮，如果切换到最后一个禁用右边按钮

实现方式： 这里我们使用 vue-awesome-swiper 默认安装的最新版本 已经支持vue3和ts

1. 安装

npm install swiper vue-awesome-swiper --save 或者 yarn add swiper vue-awesome-swiper

2. 引入插件 这里我使用的是全局引入（main.js里面引入插件）

// 引入vue-awesome-swiper
import SwiperClass, { Pagination, Grid, Mousewheel } from 'swiper'
import VueAwesomeSwiper from 'vue-awesome-swiper'
import 'swiper/css'
import 'swiper/css/pagination'
// use swiper modules
SwiperClass.use([Pagination, Grid, Mousewheel])

3. 组件里就可以使用这个插件了

<script setup lang="ts">
import { ref } from 'vue'
import SwiperClass from 'swiper'
// vertical swiper
let vSwiperRef: SwiperClass | null = null
const setVSwiperRef = (swiper: SwiperClass) => {
  vSwiperRef = swiper
}
let vSwiperIndex = ref<number>(0)
const updateVSwiperIndex = () => {
  vSwiperIndex.value = vSwiperRef?.activeIndex || 0
}
// 切换到上一页
const prevVSwiperSlide = () => vSwiperRef?.slidePrev()
// 切换到下一页
const nextVSwiperSlide = () => vSwiperRef?.slideNext()
</script>

  <div class="box">
    <div class="arrow">
      <a
        href="javascript:;"
        @click="prevVSwiperSlide"
        :class="{ disabled: vSwiperIndex === 0 }"
        class="iconfont prev"
        >&lt;</a
      >
      <a
        href="javascript:;"
        :class="{ disabled: vSwiperIndex === 5 }"
        @click="nextVSwiperSlide"
        class="iconfont next"
        >&gt;</a
      >
    </div>
    <swiper
