Vue使用Swiper看这一篇就够了

此案例实现需求

完成swiper动态异步数据下的slide渲染

自定义分页器样式

解决loop:true设置时的事件丢失问题

swiper鼠标移入/移出暂停/开始轮播

单页面渲染多个swiper组件互不影响

1、引入swiper npm i swiper@5.2.0 2、创建轮播图组件CarouselContainer.vue，详细解析在代码注释中

<template>
  <div class="CarouselContainer" @mouseenter="stopAutoPlay" @mouseleave="startAutoPlay">
    <div ref="mySwiper" class="swiper-container" :id="currentIndex"  >
      <div class="swiper-wrapper">
        <div class="swiper-slide my-swiper-slide" v-for="(item,index) of slideList" :key="index">{{item.name}}</div>
      </div>
      <!-- 分页器 -->
      <div class="swiper-pagination"></div>
      <!--导航器-->
      <div class="swiper-button-prev"></div>
      <div class="swiper-button-next"></div>
    </div>
  </div>
</template>
<script>
import Swiper from 'swiper'
import "swiper/css/swiper.css";
export default {
  name: 'CarouselContainer',
  props: ['slideList','currentIndex'],
  data(){
    return {
      currentSwiper:null,
    }
  },
  watch:{
    //slide数据发生变化时,更新swiper
    slideList:{
      deep:true,
      // eslint-disable-next-line
      handler(nv,ov){
        console.log("数据更新了")
        this.updateSwiper()
      }
    }
  },
  mounted() {
    this.initSwiper()
  },
  methods:{
    //鼠标移入暂停自动播放
    stopAutoPlay() {
       this.currentSwiper.autoplay.stop()
    },
    //鼠标移出开始自动播放
    startAutoPlay() {
      this.currentSwiper.autoplay.start()
    },
    //初始化swiper
    initSwiper(){
      // eslint-disable-next-line
      let vueComponent=this//获取vue组件实例
      //一个页面有多个swiper实例时，为了不互相影响,绑定容器用不同值或变量绑定
      this.currentSwiper = new Swiper('#'+this.currentIndex, {
        loop: true, // 循环模式选项
        autoHeight:'true',//开启自适应高度,容器高度由slide高度决定
        //分页器
        pagination: {
          el: '.swiper-pagination',
          clickable:true,//分页器按钮可点击
        },
        on: {
          //此处this为swiper实例
          //切换结束获取slide真实下标
          slideChangeTransitionEnd: function(){
            console.log(vueComponent.$props.currentIndex+"号swiper实例真实下标",this.realIndex)
          },
          //绑定点击事件,解决loop:true时事件丢失
          // eslint-disable-next-line
          click: function(event){
            console.log("你点击了"+vueComponent.$props.currentIndex+"号swiper组件")
          }
        },
        //导航器
        navigation: {
          nextEl: '.swiper-button-next',
          prevEl: '.swiper-button-prev',
        },
        autoplay: {
          //自动播放,不同版本配置方式不同
          delay: 3000,
          stopOnLastSlide: false,
          disableOnInteraction: false
        },
        slidesPerView: 1, //视口展示slide数1
        slidesPerGroup: 1, //slide数1页一组
      })
    },
    //销毁swiper
    destroySwiper(){
        try {
          this.currentSwiper.destroy(true,false)
        }catch (e) {
          console.log("删除轮播")
        }
    },
    //更新swiper
    updateSwiper(){
      this.destroySwiper()
      this.$nextTick(()=>{
        this.initSwiper()
      })
    },
  },
  destroyed() {
    this.destroySwiper()
  }
}
</script>
<style scoped>
  .CarouselContainer{
    background-color: gray;
  }
  /*slide样式*/
  .my-swiper-slide{
    height: 300px;
    background-color: pink;
  }
  /*swiper容器样式*/
  .swiper-container {
    width: 700px;
    border: 1px solid red;
  }
  /*自定义分页器按钮被点击选中时的样式*/
  /deep/.swiper-pagination-bullet-active{
    background-color: #d5a72f !important;
    width: 20px;
  }
  /*自定义分页器按钮常规样式*/
  /deep/.swiper-pagination-bullet{
    background-color: #9624bf;
    opacity: 1;
    width: 20px;
  }
</style>

3、创建父组件App.vue渲染多个swiper组件、模拟异步数据变化

<template>
  <div id="app">
    <!--传递不同的currentIndex 作为区分不同swiper组件的动态id-->
    <CarouselContainer :slide-list="list" currentIndex="1"></CarouselContainer>
    <CarouselContainer :slide-list="list" currentIndex="2"></CarouselContainer>
  </div>
</template>
<script>
import CarouselContainer from './components/CarouselContainer.vue'
export default {
  name: 'App',
  components: {
    CarouselContainer,
  },
  data(){
    return{
      list:[
        {name:"aaa"},
        {name:"bbb"},
        {name:"ccc"},
      ]
    }
  },
  mounted() {
    let self=this
    //延时模拟两次数据变化
    setTimeout(()=>{
      let obj={name:"ddd"}
      self.list.push(obj)
    },5000)
    setTimeout(()=>{
      let obj={name:"eee"}
      self.list[0].name="AAA"
      self.list.push(obj)
    },8000)
  }
}
</script>
<style scoped>
</style>

只需要这两个文件就可以vue项目中运行demo查看效果了
