antd是用的3+版本

<a-menu v-model:selectedKeys="selectedKeys" mode="inline" @click="toPage"><template v-for="i in menus"><a-menu-item v-if="!i.children" :key="i.path"><span>{{ i.name }}</span></a-menu-item><a-sub-menu v-else :key="i.path"><template #title><span>{{i.name}}</span></template><a-menu-item v-for="item in i.children" :key="item.path">{{item.name}}</a-menu-item></a-sub-menu></template>
</a-menu>

import { ref,onMounted } from 'vue';
import {menus} from '@/apis/api/nav.ts'
import { useRouter,useRoute } from 'vue-router';const router = useRouter();
const route = useRoute();
const selectedKeys = ref<string[]>(['/index']);const toPage = (e:any) => {if(e.key!=route.path){router.push({path: e.key})}
}onMounted(()=>{router.push({path: '/index'})
})

nav.ts的配置

export const menus = [
{name:'首页',path:'/index',key:'1'
},
{name:'运营管理',path:'',key:'6',children:[{name:'用户反馈管理',path:'/feedback'}]
},
]
