实现swiper 3d 轮播效果

先上个效果图，代码可以直接拿~

安装swiper和vue-awesome-swiper

因为项目用的是nuxt2，所以考虑到swiper的兼容问题，选择的是"swiper": “^5.2.0”

首先是安装swiper和vue-awesome-swiper，并指定版本

npm install swiper@5.2.0 --save

npm install vue-awesome-swiper@4.1.1 --save

然后引入，在nuxt.config.js中引入

css: [
    'swiper/css/swiper.css'
],
plugins: [
    { src: '@/plugins/vue-swiper', ssr: false }
],

基本用法

在plugins下新建一个vue-swiper.js

import Vue from 'vue'
import VueAwesomeSwiper from 'vue-awesome-swiper'
Vue.use(VueAwesomeSwiper)

在components下新建一个VueSwiper.vue

<template>
  <div v-if="initStatus" v-swiper:mySwiper="swiperOption" class="swiper mySwiper swiperBox">
    <div class="swiper-wrapper">
      <div class="swiper-slide" v-for="(item, index) in list.value" :key="index">
        <div class="pr">
          <div class="swiper-slide-imgbox uf uf-ac uf-jc">
            <img :src="item.imageUrl" />
          </div>
          <div class="font12 c8 txt-box">{{ item.title }}</div>
        </div>
      </div>
    </div>
    <div class="swiper-button-prev"></div>
    <div class="swiper-button-next"></div>
  </div>
</template>
<script>
export default {
  props: {
    list: {//banner数组
      type: Object,
      default: function () {
        return {}
      }
    },
    slidesPerView: {//一页显示几个
      type: Number,
      default: 1
    }
  },
  data() {
    return {
      initStatus: false,//初始化状态
      swiperOption: {},//swiper参数
    }
  },
  mounted() {
    let self = this;
    this.$nextTick(() => {
      this.swiperOption = {
        loop: true,
        loopAdditionalSlides: 3,
        coverflowEffect: {
          rotate: 60, //侧转角度（正值凹陷）
          stretch: -80,//每个slide之间拉伸值（正值紧贴）
          depth: 100,  //值越大为远景（可负值）
          modifier: 1, //depth和rotate和stretch的倍率
          shadows: false
       },
        centeredSlides: true,
        initialSlide: 1,
        slidesPerView: self.slidesPerView,//一页显示几个
        spaceBetween: 10,//间隔
        updateOnWindowResize: true,
        watchSlidesProgress: true,//
        noSwiping: true,//
        effect: 'coverflow', //设置Slide的切换效果，默认为"slide"（普通位移切换），还可设置为"fade"（淡入）、"cube"（方块）、"coverflow"（3d流）、"flip"（3d翻转）、"cards"(卡片式)、"creative"（创意性）。
        freeMode: 1,
        autoplay: {//自动轮播//
          delay: 3000, //
          disableOnInteraction: false,//操作swiper后 自动轮播不会停止//
        },
        navigation: {
          nextEl: '.swiper-button-next',
          prevEl: '.swiper-button-prev',
        },
      }
      this.initStatus = true //渲染swiper
    })
  },
}
</script>
<style lang="scss" scoped>
.swiper {
  margin-left: auto;
  margin-right: auto;
  position: relative;
  box-sizing: border-box;
}
.swiper-wraper {
  width: 100%;
  height: 100%;
  z-index: 1;
  display: flex;
  box-sizing: content-box;
}
.swiper-slide {
  flex-shrink: 0;
  width: 100%;
  height: 100%;
}
.swiper-slide-imgbox{
  width: 315px;
  height: 302px;
  opacity: 1;
  background: rgba(255, 255, 255, 1);
  padding: 20px;
  box-sizing: border-box;
}
.pr{
  position: relative;
}
.txt-box{
  position: absolute;
  bottom: -40px;
  left: 0;
  right: 0;
  margin: 0 auto;
}
</style>

在plugins下引入

// 引入vue 及 组件
import Vue from 'vue'
import VueSwiper from '@/components/VueSwiper'

// 全局注册组件
Vue.component('VueSwiper', VueSwiper)

然后是使用这个组件，在pages下新建一个honor.vue

<template>
  <div class="main-container">
    <PageHeader />

    <!-- banner -->
    <div class="banner-box">
      <div class="font48 weight700 c3">资质与荣誉</div>
      <div class="font16 weight400 c7 op7 mt30">Qualifications and Honors</div>
    </div>

    <div class="content-box" v-for="(honorItem, index) in honorTypes" :key="index">
      <div class="font36 pt100 mb40 vc" v-if="honorInfo[index] && honorInfo[index].value && honorInfo[index].value.length">{{ honorItem.title }}</div>
      <div class="review-content" v-if="honorInfo[index] && honorInfo[index].value && honorInfo[index].value.length">
        <vue-swiper :list="honorInfo[index]" :slidesPerView="3"></vue-swiper>
      </div>
    </div>

    <PageFooter />
  </div>
</template>

<script>
import { shareToWechat } from "../../utils/format";
export default {
  name: "Honor",

  data() {
    return {
      showType: "honor",
      honorTypes: [],
      honors: [],
      honorInfo: []
    };
  },

  methods:{
    async findHonorTypeData() {
      let _params = {
        order: 'sort'
      }
      this.loading = true;
      const res = await this.$axios.$get("/certType", { params: _params });
      this.loading = false;
      let _this = this
      if (res && res.status === 0) {
        this.honorTypes = res.result
        res.result.forEach((item, i) => {
          _this.findHonorsData(item.title)
        })
      } else {
        this.$message.error(res.message);
      }
    },

    async findHonorsData(certType) {
      let _params = {
        order: 'sort',
        certType: certType,
        pageNum: 1,
        pageSize: 30
      }
      this.loading = true;
      const res = await this.$axios.$get("/certList", { params: _params });
      this.loading = false;
      let _this = this
      if (res && res.status === 0) {
        res.result.rows.forEach((item, i) => {
          item.imageUrl = `/images${item.imageUrl}`
        })
        let _obj = {
          name: certType,
          value: res.result.rows
        }
        _this.honorInfo.push(_obj)
      } else {
        this.$message.error(res.message);
      }
    },
  },

  mounted () {
    this.findHonorTypeData()
  }
};

出现空白页的bug

使用了swiper的coverflowEffect效果，设置了同时显示3个，同时开启了loop模式。

当切换到倒数第二张时没有新的slider生成，导致最后一张的右边是空白的，只有切换到最后一张时才会再在后面复制新的slider，怎么让它在显示倒数第二张时就生成新的slider？

最后发现slidesPerView设置为auto，就正常了

然后调整coverflowEffect里的stretch和depth来弄就没问题了
