十四、文章分类添加编辑 [element-plus 弹层]

Git仓库：https://gitee.com/msyycn/vue3-hei-ma.git

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>

2. 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>

2. 通过 ref 绑定

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

3. 点击调用方法显示弹窗

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

ChannelEdit.vue(封装的组件)

<script setup>
import {ref} from 'vue'const dialogVisible = ref(false) //弹层状态// 组件对外暴露一个方法，open ,基于open 传来的参数，区分添加还是编辑
// open ({}) => 表单无需渲染，说明是添加分
// open ({id, name}) => 表单需要渲染，说明是编辑分类
// open调用后，可以打开弹窗
const open = (row) =>{console.log(row)dialogVisible.value = true}
// 向外暴露一个方法，close，关闭弹窗
defineExpose({open
})
</script><template>//弹层<el-dialogv-model="dialogVisible"title="添加弹层"width="500":before-close="handleClose"><div>渲染表单</div><span>我是内容部分  </span><template #footer><div class="dialog-footer"><el-button @click="dialogVisible = false">取消</el-button><el-button type="primary" @click="dialogVisible = false">确认</el-button></div></template></el-dialog>
</template>

ArticleChannel.vue

<script setup>
import { artGetChannelsService } from '@/api/article'
import { Delete,Edit } from   '@element-plus/icons-vue'import {ref} from 'vue'
import ChannelEdit from './components/ChannelEdit.vue'
const channelList = ref([]) // 文章分类列表
const loading = ref(false) //加载状态const dialog = ref()
// 获取文章分类列表

getChannelList()// 编辑文章分类
const onEditChannel =(row) =>{
// console.log(row,$index)

}       // 删除文章分类
const onDelChannel =(row,$index)=>{console.log(row,$index)}
const onAddChannel = () => {dialog.value.open({})
}</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 @click="onAddChannel">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><!-- 没有数据 --><template #empty><el-empty description="暂无数据"></el-empty></template></el-table><!-- 添加分类弹窗 --><channel-edit ref="dialog"> </channel-edit></page-container></div>

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'}]
}

2. 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>

3. 编辑需要回显，表单数据需要初始化

const open = async (row) => {dialogVisible.value = trueformModel.value = { ...row }//不回显的话，需要修改为// formModel.value = {...row.row} 即可
}

4. 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)

2. 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
}

3. 通知父组件进行回显

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

4. 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 }})

2. 页面中添加确认框，调用接口进行提示（ArticleChannel.vue)

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()
}
