首页 layout 架子 [element-plus 菜单]

基本架子拆解

架子组件列表：

el-container

• el-aside 左侧

  • el-menu 左侧边栏菜单

• el-container 右侧

  • el-header 右侧头部
    • el-dropdown
  • el-main 右侧主体
    • router-view

<script setup>

} from '@element-plus/icons-vue'
import avatar from '@/assets/default.png'

登录访问拦截

需求：只有登录页，可以未授权的时候访问，其他所有页面，都需要先登录再访问

// 登录访问拦截
router.beforeEach((to) => {const userStore = useUserStore()if (!userStore.token && to.path !== '/login') return '/login'
})

用户基本信息获取&渲染

1. api/user.js封装接口

export const userGetInfoService = () => request.get('/my/userinfo')

1. stores/modules/user.js 定义数据

const user = ref({})
const getUser = async () => {const res = await userGetInfoService() // 请求获取数据user.value = res.data.data
}

1. layout/LayoutContainer页面中调用

import { useUserStore } from '@/stores'
const userStore = useUserStore()
onMounted(() => {userStore.getUser()
})

1. 动态渲染

<div>黑马程序员：<strong>{{ userStore.user.nickname || userStore.user.username }}</strong>
</div><el-avatar :src="userStore.user.user_pic || avatar" />

退出功能 [element-plus 确认框]

1. 注册点击事件

<el-dropdown placement="bottom-end" @command="onCommand"><el-dropdown-menu><el-dropdown-item command="profile" :icon="User">基本资料</el-dropdown-item><el-dropdown-item command="avatar" :icon="Crop">更换头像</el-dropdown-item><el-dropdown-item command="password" :icon="EditPen">重置密码</el-dropdown-item><el-dropdown-item command="logout" :icon="SwitchButton">退出登录</el-dropdown-item>
</el-dropdown-menu>

1. 添加退出功能

const onCommand = async (command) => {if (command === 'logout') {await ElMessageBox.confirm('你确认退出大事件吗？', '温馨提示', {type: 'warning',confirmButtonText: '确认',cancelButtonText: '取消'})userStore.removeToken()userStore.setUser({})router.push(`/login`)} else {router.push(`/user/${command}`)}
}

1. pinia user.js 模块 提供 setUser 方法

const setUser = (obj) => (user.value = obj)

文章分类页面 - [element-plus 表格]

基本架子 - PageContainer

1. 基本结构样式，用到了 el-card 组件

<template><el-card class="page-container"><template #header><div class="header"><span>文章分类</span><div class="extra"><el-button type="primary">添加分类</el-button></div></div></template>...</el-card>
</template><style lang="scss" scoped>
.page-container {min-height: 100%;box-sizing: border-box;.header {display: flex;align-items: center;justify-content: space-between;}
}
</style>

1. 考虑到多个页面复用，封装成组件
   • props 定制标题
   • 默认插槽 default 定制内容主体
   • 具名插槽 extra 定制头部右侧额外的按钮

<script setup>
defineProps({title: {required: true,type: String}
})
</script><template><el-card class="page-container"><template #header><div class="header"><span>{{ title }}</span><div class="extra"><slot name="extra"></slot></div></div></template><slot></slot></el-card>
</template><style lang="scss" scoped>
.page-container {min-height: 100%;box-sizing: border-box;.header {display: flex;align-items: center;justify-content: space-between;}
}
</style>

1. 页面中直接使用测试 ( unplugin-vue-components 会自动注册)

• 文章分类测试：

<template><page-container title="文章分类"><template #extra><el-button type="primary"> 添加分类 </el-button></template>主体部分</page-container>
</template>

• 文章管理测试：

<template><page-container title="文章管理"><template #extra><el-button type="primary">发布文章</el-button></template>主体部分</page-container>
</template>

文章分类渲染

封装API - 请求获取表格数据

1. 新建 api/article.js 封装获取频道列表的接口

import request from '@/utils/request'
export const artGetChannelsService = () => request.get('/my/cate/list')

1. 页面中调用接口，获取数据存储

const channelList = ref([])const getChannelList = async () => {const res = await artGetChannelsService()channelList.value = res.data.data
}

el-table 表格动态渲染

<el-table :data="channelList" style="width: 100%"><el-table-column label="序号" width="100" type="index"> </el-table-column><el-table-column label="分类名称" prop="cate_name"></el-table-column><el-table-column label="分类别名" prop="cate_alias"></el-table-column><el-table-column label="操作" width="100"><template #default="{ row }"><el-button:icon="Edit"circleplaintype="primary"@click="onEditChannel(row)"></el-button><el-button:icon="Delete"circleplaintype="danger"@click="onDelChannel(row)"></el-button></template></el-table-column><template #empty><el-empty description="没有数据" /></template>
</el-table>const onEditChannel = (row) => {console.log(row)
}
const onDelChannel = (row) => {console.log(row)
}

el-table 表格 loading 效果

1. 定义变量，v-loading绑定

const loading = ref(false)<el-table v-loading="loading">

1. 发送请求前开启，请求结束关闭

const getChannelList = async () => {loading.value = trueconst res = await artGetChannelsService()channelList.value = res.data.dataloading.value = false
}

文章分类添加编辑 [element-plus 弹层]

点击显示弹层

1. 准备弹层

const dialogVisible = ref(false)<el-dialog v-model="dialogVisible" title="添加弹层" width="30%"><div>我是内容部分</div><template #footer><span class="dialog-footer"><el-button @click="dialogVisible = false">取消</el-button><el-button type="primary"> 确认 </el-button></span></template>
</el-dialog>

1. 点击事件

<template #extra><el-button type="primary" @click="onAddChannel">添加分类</el-button></template>const onAddChannel = () => {dialogVisible.value = true
}

封装弹层组件 ChannelEdit

添加 和 编辑，可以共用一个弹层，所以可以将弹层封装成一个组件

组件对外暴露一个方法 open, 基于 open 的参数，初始化表单数据，并判断区分是添加 还是 编辑

1. open({ }) => 添加操作，添加表单初始化无数据
2. open({ id: xx, … }) => 编辑操作，编辑表单初始化需回显

具体实现：

1. 封装组件 article/components/ChannelEdit.vue

<script setup>
import { ref } from 'vue'
const dialogVisible = ref(false)const open = async (row) => {dialogVisible.value = trueconsole.log(row)
}defineExpose({open
})
</script><template><el-dialog v-model="dialogVisible" title="添加弹层" width="30%"><div>我是内容部分</div><template #footer><span class="dialog-footer"><el-button @click="dialogVisible = false">取消</el-button><el-button type="primary"> 确认 </el-button></span></template></el-dialog>
</template>

1. 通过 ref 绑定

const dialog = ref()<!-- 弹窗 -->
<channel-edit ref="dialog"></channel-edit>

1. 点击调用方法显示弹窗

const onAddChannel = () => {dialog.value.open({})
}
const onEditChannel = (row) => {dialog.value.open(row)
}

准备弹层表单

1. 准备数据 和 校验规则

const formModel = ref({cate_name: '',cate_alias: ''
})
const rules = {cate_name: [{ required: true, message: '请输入分类名称', trigger: 'blur' },{pattern: /^\S{1,10}$/,message: '分类名必须是1-10位的非空字符',trigger: 'blur'}],cate_alias: [{ required: true, message: '请输入分类别名', trigger: 'blur' },{pattern: /^[a-zA-Z0-9]{1,15}$/,message: '分类别名必须是1-15位的字母数字',trigger: 'blur'}]
}

1. 准备表单

<el-form:model="formModel":rules="rules"label-width="100px"style="padding-right: 30px"
><el-form-item label="分类名称" prop="cate_name"><el-inputv-model="formModel.cate_name"minlength="1"maxlength="10"></el-input></el-form-item><el-form-item label="分类别名" prop="cate_alias"><el-inputv-model="formModel.cate_alias"minlength="1"maxlength="15"></el-input></el-form-item>
</el-form>

1. 编辑需要回显，表单数据需要初始化

const open = async (row) => {dialogVisible.value = trueformModel.value = { ...row }
}

1. 基于传过来的表单数据，进行标题控制，有 id 的是编辑

:title="formModel.id ? '编辑分类' : '添加分类'"

确认提交

1. api/article.js 封装请求 API

// 添加文章分类
export const artAddChannelService = (data) => request.post('/my/cate/add', data)
// 编辑文章分类
export const artEditChannelService = (data) =>request.put('/my/cate/info', data)

1. 页面中校验，判断，提交请求

<el-form ref="formRef">

const formRef = ref()
const onSubmit = async () => {await formRef.value.validate()formModel.value.id? await artEditChannelService(formModel.value): await artAddChannelService(formModel.value)ElMessage({type: 'success',message: formModel.value.id ? '编辑成功' : '添加成功'})dialogVisible.value = false
}

1. 通知父组件进行回显

const emit = defineEmits(['success'])const onSubmit = async () => {...emit('success')
}

1. 父组件监听 success 事件，进行调用回显

<channel-edit ref="dialog" @success="onSuccess"></channel-edit>const onSuccess = () => {getChannelList()
}

文章分类删除

1. api/article.js封装接口 api

// 删除文章分类
export const artDelChannelService = (id) =>request.delete('/my/cate/del', {params: { id }})

1. 页面中添加确认框，调用接口进行提示

const onDelChannel = async (row) => {await ElMessageBox.confirm('你确认删除该分类信息吗？', '温馨提示', {type: 'warning',confirmButtonText: '确认',cancelButtonText: '取消'})await artDelChannelService(row.id)ElMessage({ type: 'success', message: '删除成功' })getChannelList()
}
