解决Vue的项目使用Element ui 走马灯无法实现的问题

<el-carousel height="150px">
<el-carousel-item v-for="item in imgList" :key="item" height="300px" >
<h3><img :src="item" alt=""> </h3>
</el-carousel-item>
</el-carousel>

<script>
export default {
data(){
return {
imgList:[
require('../../assets/img/images/a1.png'),
require('../../assets/img/images/a2.png'),
require('../../assets/img/images/a3.png'),
require('../../assets/img/images/a4.png'),
require('../../assets/img/images/a5.png')
]
}
},
components: {
}
}
</script>

data() {
 return{
 // 图片需要引入, 否则无法显示
 imgList: [
   {id: 0, idView: require('../assets/images/banner3.jpg')},
   {id: 1, name: '详情', idView: require('../assets/images/banner2.jpg')},
   {id: 2, name: '推荐', idView: require('../assets/images/banner1.jpg')}
  ]
 }
}

<template> 
 <el-carousel :interval="5000" arrow="always" class="d_jump" :height="imgHeight">
 <el-carousel-item v-for="item in imgList" :key="item.id">
  <el-row>
  <el-col :span="24"><img ref="imgHeight" :src="item.idView" class="banner_img"/></el-col>
  </el-row>
 </el-carousel-item>
 </el-carousel>
</template>

that.imgHeight = '620px'
window.onresize = function temp() {
 // 通过点语法获取img的height属性值
 that.imgHeight = `${that.$refs.imgHeight['0'].height}px`
}
