vue中动态引入图片地址需要用require

如果icon的地址是相对于项目根目录的路径,
动态引入图片地址时需要添加require()

动态生成menu

            <el-menu default-active="2" class="el-menu-vertical-demo" @open="handleOpen" @close="handleClose"
                     :collapse="isCollapse">
                <el-menu-item :index="mindex+1" v-for="(mitem,mindex) in menuList" :key="mindex">
                    <img :src="mitem.icon" alt="">
                    <span slot="title">{{mitem.name}}</span>
                </el-menu-item>
            </el-menu>

menuList

menuList:[
    {name:'数据概览',icon:require('@/assets/img/global/menu11.png'),iconActive:require('@/assets/img/global/menu12.png')},
    {name:'数据引接',icon:require('@/assets/img/global/menu11.png'),iconActive:require('@/assets/img/global/menu12.png')},
    {name:'数据检索',icon:require('@/assets/img/global/menu11.png'),iconActive:require('@/assets/img/global/menu12.png')},
