十三、文章分类页面 - [element-plus 表格]
Git仓库：https://gitee.com/msyycn/vue3-hei-ma.git
基本架子 - PageContainer
功能需求说明：
- 基本架子-PageContainer封装
- 文章分类渲染 & loading处理
- 文章分类添加编辑[element-plus弹层]
- 文章分类删除
- 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>
- 考虑到多个页面复用，封装成组件
props定制标题(父传子)- 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>
- 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
- 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')
- 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
}
ArticleChannel.vue
<script setup>
import { artGetChannelsService } from '@/api/article'
import {ref} from 'vue'const channelList = ref([]) // 文章分类列表
// 获取文章分类列表
const getChannelList = async () => {const res = await artGetChannelsService()channelList.value = res.data.dataconsole.log('文章分类列表',channelList.value);}// 调用获取文章分类列表
getChannelList()
</script><template><div><!-- 按需引入 --><page-container title="文章分类"> <!-- 右侧按钮 - 添加文章 - 具名插槽 --><template #extra><el-button>添加分类</el-button></template>主体部分--表格</page-container></div>
</template><style lang="scss" scoped>
</style>视图预览
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
- 定义变量，v-loading绑定
const loading = ref(false)<el-table v-loading="loading">
- 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
}
ArticleChannel.vue
<script setup>
import { artGetChannelsService } from '@/api/article'
import { Delete,Edit } from '@element-plus/icons-vue'import {ref} from 'vue'const channelList = ref([]) // 文章分类列表
const loading = ref(false) //加载状态
// 获取文章分类列表
const getChannelList = async () => {// 发请求之前先将loading设置为trueloading.value = true// 调用接口const res = await artGetChannelsService()channelList.value = res.data.data// 发完请求，关闭loadingloading.value = false// console.log('文章分类列表',channelList.value);}// 调用获取文章分类列表
getChannelList()// 编辑文章分类
const onEditChannel =(row,$index) =>{
console.log(row,$index)}// 删除文章分类
const onDelChannel =(row,$index)=>{console.log(row,$index)}
</script><template><div><!-- 按需引入 --><page-container title="文章分类"> <!-- 右侧按钮 - 添加文章 - 具名插槽 --><template #extra><el-button>添加分类</el-button></template><!-- 主体部分--表格 --><el-table :data="channelList" style="width: 100%" v-loading="loading"><el-table-column label="序号" type="index" width="100" ></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,$index}"><el-button @click="onEditChannel(row,$index)" plain :icon="Edit" circle type="primary" ></el-button><el-button @click="onDelChannel(row,$index)" plain :icon="Delete" circle type="danger" ></el-button></template></el-table-column></el-table></page-container></div>
</template><style lang="scss" scoped>
</style>
请求到的数组为空时
channelList.value = []
添加element-plus插槽：
<!-- 主体部分--表格 --><el-table :data="channelList" style="width: 100%" v-loading="loading"><el-table-column label="序号" type="index" width="100" ></el-table-column><el-table-column label="分类名称" prop="cate_name" ></el-table-column><el-table-column label="分类别名" prop="cate_alias" ></el-table-column><el-table-column label="操作" width="100"><template #default="{row,$index}"><el-button @click="onEditChannel(row,$index)" plain :icon="Edit" circle type="primary" ></el-button><el-button @click="onDelChannel(row,$index)" plain :icon="Delete" circle type="danger" ></el-button></template></el-table-column><!-- 没有数据 --><template #empty><el-empty description="暂无数据"></el-empty></template></el-table>
