vue3封装Element导航菜单

1. 导航外层布局 AsideView.vue

<template><el-menu:default-active="defaultActive"class="my-menu":collapse="isCollapse":collapse-transition="false"@open="handleOpen"@close="handleClose"><menu-item :menuList="menuList"></menu-item></el-menu>
</template><script lang="ts" setup>
import { useRoute } from "vue-router";import MenuItem from "./components/MenuItem.vue";
const collapseStore = useCollapseStore();
const isCollapse = computed(() => collapseStore.collapse);
const store = useMenuStore();
const menuList = store.menuList;
const flattenMenuList = store.flattenMenuList();
const defaultActive = ref("");
onMounted(() => {const route = useRoute();watch(() => route.fullPath,(newPath, oldPath) => {getDefaultActive(newPath);},{immediate: true,});
});const getDefaultActive = (path) => {const currentMenu = flattenMenuList.find((item) => item.path === path);if (currentMenu) {defaultActive.value = currentMenu.id;}console.log("defaultActive", defaultActive.value);
};const handleOpen = (key: string, keyPath: string[]) => {console.log(key, keyPath);
};
const handleClose = (key: string, keyPath: string[]) => {console.log(key, keyPath);
};
</script><style lang="scss">
.icon-collapse {cursor: pointer;width: 64px;height: 30px;margin: 0 auto;
}
.my-menu {background-color: #545c64;border-right: none;color: #fff;height: 100%;overflow-x: hidden;overflow-y: auto;
}
.el-menu-item,
.el-sub-menu__title {background-color: #545c64;color: #fff;
}
.el-menu-item:hover,
.el-sub-menu__title:hover {background: rgb(62, 64, 74);
}
.el-menu-item.is-active,
.el-sub-menu__title.is-active {background: rgb(62, 64, 74);
}
/* 滚动条 */
::-webkit-scrollbar {/*滚动条整体样式*/width: 7px; /*高宽分别对应横竖滚动条的尺寸*/height: 7px;&-thumb {/*滚动条里面小方块*/border-radius: 7px;background-color: #d0d0d0;&:hover {/*滚动条里面小方块*/background-color: #b7b7b7;}}&-track {/*滚动条里面轨道*/border-radius: 7px;background-color: #fff;}
}
</style>

2. 单个导航菜单封装 MenuItem.vue

<template><template v-for="item in menuList" :key="item.id"><el-sub-menu:index="item.id"v-if="item.children && item.children.length > 0"><template #title><el-icon :size="30"><component class="fold-menu" :is="item.icon"></component></el-icon><span>{{ item.name }}</span></template><menu-item :menuList="item.children"></menu-item></el-sub-menu><el-menu-item :index="item.id" v-else @click="handleJump(item)"><el-icon :size="30"><component class="fold-menu" :is="item.icon"></component></el-icon><template #title>{{ item.name }}</template></el-menu-item></template>
</template>
<script setup lang="ts">
import { useRouter } from "vue-router";
import type { MenuInfo } from "~/types/menu";
const router = useRouter();const props = defineProps({menuList: {type: Array<MenuInfo>,},
});const handleJump = (item: MenuInfo) => {if (item.path) {router.push(item.path);}
};
</script><style lang="scss" scoped></style>

3. 控制导航收缩 stores/collapse.ts

import { ref } from 'vue'
import { defineStore } from 'pinia'export const useCollapseStore = defineStore('collapse', () => {const collapse = ref(false)const changeCollapse = function changeCollapse() {collapse.value = !collapse.value}return { collapse, changeCollapse }
})

4. 菜单数据格式示例

  const menuList = ref<MenuInfo[]>([{id: '1',name: '首页',path: '/',icon: 'HomeFilled',},{id: '2',name: '用户管理',path: '/user-manage',icon: 'UserFilled',},{id: '3',name: '权限管理',path: '/permission',icon: 'Lock',},{id: '4',name: '商品管理',path: '/product',icon: 'ShoppingBag',children: [{id: '4-1',name: '商品列表',path: '/product/list',icon: 'ShoppingBag'}]},{id: '5',name: '订单管理',path: '/order',icon: 'Document',children: [{id: '5-1',name: '订单列表',path: '/order/list',icon: 'Document'}]},{id: '6',name: '数据统计',path: '/data',icon: 'DataAnalysis'},{id: '7',name: '系统设置',path: '/system',icon: 'Setting'},{id: '8',name: '其他',path: '/other',icon: 'Document'}])
