vue中引入图片

1.在img标签里面直接写上路径：（静态）

<img src="../assets/a1.png" class="" width="100%"/>

2.利用数组保存再循环输出：（动态）

<el-carousel-item v-for="item in carouselData" :key="item.id">
        <img :src="item.url" class="carouselImg"/>
        <span class="carouselSpan">{{ item.title }}</span>
</el-carousel-item>
data: () => ({
      carouselData:[
      {url:require('../assets/a1.png'),title:'图片1',id:1},
      {url:require('../assets/a3.png'),title:'图片2',id:2},
      {url:require('../assets/a4.png'),title:'图片3',id:3}
      ]
    }),
