vue2踩坑之项目：Swiper轮播图使用

首先安装swiper插件

npm i swiper@5

安装出现错误：npm ERR

解决方法：npm 版本太高，切换一下就好了

如下代码 运行后再重新 npm i

npm install npm@6.14.15 -g

引入Swiper

// 可以直接在组件里引入这个文件

//导入js

import Swiper from "swiper";

//引入css

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

代码：

//html结构
 
 
//js
//mounted里面调用
export default {
  components: {
  },
  setup() {
    return {
      // modules: [Pagination],
    };
  },
  methods: {
 
  },
  mounted() {
    var Myswiper = new Swiper(".swiper-container", {
      loop: true, // 循环模式选项
      slidesPerView: 3,
      centeredSlides: true,
      centeredSlidesBounds: true,
      // 自动轮播
      autoplay: {
        delay: 1300,
        stopOnLastSlide: false,
        disableOnInteraction: true,
        waitForTransition: false,
        pauseOnMouseEnter: true, // 鼠标悬停暂停轮播
 
      },
      // 翻转
      effect: 'coverflow',
      slidesPerView: 3,
      centeredSlides: true,
      coverflowEffect: {
        rotate: 30,
        stretch: 10,
        depth: 60,
        modifier: 2,
        slideShadows: true
      },
 
 
      // 如果需要分页器
      pagination: {
        el: ".swiper-pagination",
        clickable: true,
 
      },
 
      // 下一页，上一页
      navigation: {
        nextEl: '.swiper-button-next',
        prevEl: '.swiper-button-prev',
      },
      
      // 滚动条
      scrollbar: {
        el: ".swiper-scrollbar",
        hide: true,
        draggable: true, //是否可拖动条
        snapOnRelease: true, //false释放滚动条时slide不会自动贴合
        dragSize: 500,
      },
 
    });
 
    /*鼠标移入停止轮播，鼠标离开 继续轮播*/
    var container = document.getElementById('swiperContainer');
    container.onmouseover = function () {
      Myswiper.autoplay.stop();
    };
    container.onmouseout = function () {
      Myswiper.autoplay.start();
    }
  },
 
 
//css
<style scoped lang="scss">
.swiper-container {
  position: relative;
  display: inline-block;
  width: 100%;
  height: 24rem;
  overflow: hidden;
  background-color: #ECECEC;
  --swiper-pagination-color: #ffbb00; // 分页器颜色
  /* 设置Swiper风格 */
  --swiper-theme-color: #ff6600;
  /* 单独设置按钮颜色 */
  --swiper-navigation-color: #00aaff;
  /* 设置按钮大小 */
  --swiper-navigation-size: 30px;
 
  h1 {
    color: #fff;
    position: relative;
    top: 40%;
  }
 
  .swiper-slide {
    img {
      width: 100%;
      height: 100%;
    }
 
    .bannerTitle {
      line-height: 2rem;
      width: 100%;
      position: absolute;
      height: 2rem;
      bottom: 0px;
      left: 10px;
      background: rgba(0, 0, 0, 0.5);
      color: rgba(255, 255, 255, 0.9);
      z-index: 9999;
 
      .titleC {
        width: 26rem;
        overflow: hidden;
        text-overflow: ellipsis;
        white-space: nowrap;
      }
    }
  }
}
