Vue使用Swiper封装轮播图组件的方法详解

 npm install Swiper@6            // @6 是指定版本号为6 的意思
 cnpm install Swiper@6
 yarn add Swiper@6

import "swiper/swiper-bundle.min.css";

import Swiper from 'swiper/swiper-bundle'

// 注意这里容器的类名！！
<div class="swiper-container" ref='Carousel'>       
    <div class="swiper-wrapper">
        //v-for循环生成轮播图片
        <div class="swiper-slide" v-for="Carousel in list" :key="Carousel.id">
            <img :src="Carousel.imgUrl" />
      </div>
    </div> 

    <!-- 如果需要分页器 -->
    <div class="swiper-pagination"></div> 

    <!-- 如果需要导航按钮 --> 
    <div class="swiper-button-prev"></div> 
    <div class="swiper-button-next"></div> 

    <!-- 如果需要滚动条 --> 
    <div class="swiper-scrollbar"></div>
</div>

watch: {
//list是轮播图数据
    list: {
      immediate: true,   //页面初始化的时候就调用一次handler()
      handler() {
        this.$nextTick(() => {
          var mySwiper = new Swiper(this.$refs.Carousel, {
            direction: "horizontal", // 水平切换选项
            loop: true, // 循环模式选项

            // 如果需要分页器
            pagination: {
              el: ".swiper-pagination",
              clickable: true,     //可点击
              type: "bullets",     //默认样式 小圆点, 还可选其他形状
            },

            // 如果需要前进后退按钮
            navigation: {
              nextEl: ".swiper-button-next",
              prevEl: ".swiper-button-prev",
