需求：如何components里面的index.vue怎样能把assets里面的图片拿出来。 

1.在img标签里面直接写上路径：

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

2.利用数组保存再循环输出：

<el-carousel-item v-for="item in carouselData" :key="item.id">
        <img :src="item.url"/>
        <span>{{ item.title }}</span>
</el-carousel-item>
data: () => ({
      carouselData:[
      {url:require(‘../assets/a1.png‘),title:‘你看我叼吗1‘,id:1},
      {url:require(‘../assets/a3.png‘),title:‘你看我叼吗2‘,id:2},
      {url:require(‘../assets/a4.png‘),title:‘你看我叼吗3‘,id:3}
      ]
    }),

vue中的js引入图片，必须require进来 或者引用网络地址

<template>
    <div>
        <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" >-->

                </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: [
　　　　　　　　　　　　# 错误?
                    // {id: 1, imgSrc: jpg1},
                    // {id: 2, imgSrc: jpg1},
                    // {id: 3, imgSrc: jpg1},
                    # 正确?
                    {id: 1, imgSrc: require("../assets/1.jpg")},
                    {id: 2, imgSrc: require("../assets/2.jpg")},
                    {id: 3, imgSrc: require("../assets/3.jpg")},
                    # 正确?
                    // {id: 1,imgSrc:"https://hcdn1.luffycity.com/static/frontend/index/banner1(4)_1539945492.0492468.png"},
                    // {id: 2,imgSrc:"https://hcdn1.luffycity.com/static/frontend/index/骑士(1)_1539945488.713867.png"},
                    // {id: 3,imgSrc:"https://hcdn1.luffycity.com/static/frontend/index/banner11_1538122470.2779157.png"},
                ]
            }
        },
    }
