vue2+vant+H5轮播图中间大两边小的效果_vant swip 两个

要实现如上图效果，自动轮播并且选中的图片会大一些，我们可以借助插件vue-awesome-swiper组件

1.下载插件：
npm install vue-awesome-swiper@3.1.3 -S
2.引入：
import ‘swiper/dist/css/swiper.css’
import { swiper, swiperSlide } from ‘vue-awesome-swiper’
3.注册使用
components: {
// 注册 vue-awesome-swiper 组件
swiper,
swiperSlide
},
4.点击图片事件
加 :data-preview=“item.preview”
在绑定的iptions里加on事件
on:{click:(e) => {
this.previewImg(e)
}
}

<template>
<!-- 轮播 -->
    <div class="container">
        <swiper :options="swiperOption">
          <swiper-slide v-for=" (item,index) in images" :key="index">
             <img :src="item" alt="" :data-preview= "item"/>
          </swiper-slide>
        </swiper>
    </div>
    <!-- 弹出层预览图片-->
    <van-popup v-model="show">
    	 <img :src="popImg " alt="" />
    </van-popup>
</template>
<script>
import 'swiper/dist/css/swiper.css'
import { swiper, swiperSlide } from 'vue-awesome-swiper'

export default {
  name: 'home-page',
  components: {
    // 注册 vue-awesome-swiper 组件
    swiper,
    swiperSlide
  },
 data(){
    return{
     show:false,
     popImg :'',
     images: [
        require('@/assets/more1.png'),
        require('@/assets/more2.png'),
        require('@/assets/more3.png'),
        require('@/assets/more4.png')
      ],
       swiperOption: {
        pagination: {
          el: '.swiper-pagination', // 与slot="pagination"处 class 一致
          clickable: true // 轮播按钮支持点击
        },
        //点击事件
         on:{click:(e) => {
		 	this.previewImg(e)
		 	}
		 }
        // 自动播放
        autoplay: {
          delay: 10000,
          disableOnInteraction: false
        },
        // 循环
        loop: true,
        spaceBetween: 0, // 轮播图左右间距
        slidesPerView: 1.5, // 一屏显示的slide个数，图片宽度
        centeredSlides: true, // 居中的slide是否标记为active，默认是最左active,这样样式即可生效
        slideToClickedSlide: true // 点击的slide会居中
      }
	 }
	},
	methods:{
		previewImg(e){
		//获取当前点击的图片
		this.popImg = e.target.getAttribute('data-preview'))
		//打开pop弹框
		this.show = true
		}
	}
}
