效果图如下

<template>
  <!--动态将图片轮播图的容器高度设置成与图片一致-->
 <el-carousel  height="260px" trigger="click" :autoplay="false">
      <el-carousel-item v-for="item in imagebox" :key="item.id">
        <img :src="item.idView" class="image">
      </el-carousel-item>
 </el-carousel>
</template>

<script>
  export default{
    name:'zmd',
    data(){
      return {
        imagebox:[{id:0,idView:require('../assets/banner1.jpg')},
        {id:1,idView:require('../assets/banner2.jpg')},
        {id:2,idView:require('../assets/banner3.jpg')}
        ],
         
        // 浏览器宽度
        screenWidth :0
      }
    },
     methods:{
              setSize:function () {
                // 通过浏览器宽度(图片宽度)计算高度
                this.bannerHeight = 900 / 1440 * this.screenWidth;
              },
            },
          mounted() {
              // 首次加载时,需要调用一次
              this.screenWidth =  window.innerWidth;
              this.setSize();
              // 窗口大小发生改变时,调用一次
              window.onresize = () =>{
              this.screenWidth =  window.innerWidth;
              this.setSize();
            }
          }
  }
