vue中的js引入圖片，必須require進來

需求：如何components里面的index.vue怎樣能把assets里面的圖片拿出來。 
1.在img標簽里面直接寫上路徑：

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

2.利用數組保存再循環輸出：

<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:'你看我叼嗎1',id:1},
      {url:require('../assets/a3.png'),title:'你看我叼嗎2',id:2},
      {url:require('../assets/a4.png'),title:'你看我叼嗎3',id:3}
      ]
    }),

 

vue中的js引入圖片，必須require進來 或者引用網絡地址

<template>
    <div class="home">
        <img alt="Vue logo" src="../assets/logo.png">
        <!--<HelloWorld msg="Welcome to Your Vue.js App"/>-->


        <template>
            <el-carousel :interval="4000" type="card" height="200px">
                <el-carousel-item v-for="item in imgList" :key="item.id">
                    <img :src="item.imgSrc" >
                    <!--<img :src="defimg" alt="">-->

                </el-carousel-item>
            </el-carousel>
        </template>

    </div>
</template>

<script>
    // @ is an alias to /src
    // import HelloWorld from '@/components/HelloWorld.vue'

    export default {
        name: 'home',
        // components: {
        //     HelloWorld
        // },
        data() {
            return {

                imgList: [
　　　　　　　　　　　　# 錯誤❌
                    // {id: 1, imgSrc: jpg1},
                    // {id: 2, imgSrc: jpg1},
                    // {id: 3, imgSrc: jpg1},
                    # 正確✅
                    {id: 1, imgSrc: require("../assets/1.jpg")},
                    {id: 2, imgSrc: require("../assets/2.jpg")},
                    {id: 3, imgSrc: require("../assets/3.jpg")},

                ]
            }
