Detailed explanation of vue swiper implementation of component development

I don’t know how much you know about swiper. This article mainly introduces the relevant information about vue+swiper to achieve component development. Friends who need it can refer to it. I hope it can help everyone.

Swiper's component

<template>
  <p class="swiper-container">
    <p class="swiper-wrapper">
      <p class="swiper-slide" v-for="item in swiper"><img src="/static/imghwm/default1.png"  data-src="item.room_src"  class="lazy"  : alt=""></p>
      <!--<p class="swiper-slide" v-for="item in test"><img src="/static/imghwm/default1.png"  data-src="item.room_src"  class="lazy"  : alt=""></p>-->
    </p>
  </p>
</template>
<script>
 import Swiper from &#39;swiper&#39;
 export default {
  name: &#39;swiper&#39;,
  data() {
   return {
    mySwiper: null,
//    test: [
//     "https://rpic.douyucdn.cn/acrpic/171024/288016_0921.jpg",
//     "https://rpic.douyucdn.cn/acrpic/171024/748396_0924.jpg",
//     "https://rpic.douyucdn.cn/acrpic/171024/453751_0922.jpg",
//     "https://rpic.douyucdn.cn/acrpic/171024/79663_0920.jpg"
//    ]
   }
  },
  props: [&#39;swiper&#39;], //swiper的就是test这个数据传递来的
  methods: {
   _initSwiper() {
    this.mySwiper = new Swiper(&#39;.swiper-container&#39;, {
     autoplay: 5000,//可选选项，自动滑动
    })
   },
   _updateSwiper() {
    this.$nextTick(() => {
     this.mySwiper.update(true); //swiper update的方法
    })
   },
   swiperUpdate() {
    if (this.mySwiper) { //节点存在
     this._updateSwiper(); //更新
    } else {
     this._initSwiper(); //创建
    }
   },
  },
  watch: {
   //通过props传来的数据 和 组件一加载节点就创建成功 二者不是同步，实时监听的swiper(传递的值)的变化
   swiper() {
    this.swiperUpdate();
   }
  },
  mounted() {
   this.swiperUpdate(); //页面一加载拉去数据创建节点
  }
 }
</script>
<style lang="scss" scoped>
  .swiper-container {
    width: 100%;
    height: 4rem;
    margin-top: 0.9rem;
    .swiper-wrapper {
      width: 100%;
      height: 100%;
      .swiper-slide {
        background-size: cover;
        width: 100%;
        height: 4rem;
        img {
          width: 100%;
          height: 100%;
        }
      }
    }
  }
</style>

Home.vue component method called

//html
  <swiper :swiper="roomList.slice(6,10)" ></swiper>
//js
 import swiper from &#39;components/swiper/swiper&#39;
 components: {
   swiper
  },

Problem: If you simply call _initSwiper method, you will find that the page cannot be scrolled, but the page can be modified casually, and then the saved swiper can be scrolled. This reason is that the initial swiper node was not created successfully, and the value page is penetrated, layer by layer. The value of swiper can be printed as empty, and the value can be passed in when the value is modified, so here we need to update the siwper method by judging whether the node is successful
