# Modal 弹窗
|
||
|
||
:::tip 说明
|
||
项目提供 `BasicModal` 组件（`src/components/Modal/src/BasicModal.vue`）和原生 `basicModal` 两种弹窗用法。编辑弹窗通过 `defineAsyncComponent` 懒加载，减少首屏渲染负担。
|
||
:::
|
||
|
||
## 组件架构
|
||
|
||
```
|
||
src/components/Modal/
|
||
├── src/
|
||
│ ├── BasicModal.vue # 主组件（基于 n-modal）
|
||
│ ├── props.ts # 属性定义
|
||
│ ├── type.ts # 类型定义（ModalProps、ModalMethods）
|
||
│ └── hooks/
|
||
│ └── useModalContext.ts # 弹窗上下文
|
||
└── index.ts # 导出 useModal 等
|
||
```
|
||
|
||
## BasicModal 组件
|
||
|
||
`BasicModal` 基于 NaiveUI 的 `n-modal` 封装，提供全屏切换、自定义头部、提交按钮等能力：
|
||
|
||
```vue
|
||
<basicModal title="编辑" :width="600" @register="registerModal" @on-ok="handleSubmit">
|
||
<BasicForm @register="registerForm" />
|
||
</basicModal>
|
||
```
|
||
|
||
核心功能：
|
||
|
||
- 自定义头部（标题 + 全屏/关闭按钮）
|
||
- 提交按钮自动 loading（`setSubLoading`）
|
||
- `setProps` 动态修改弹窗属性
|
||
- `openModal` / `closeModal` 控制显隐
|
||
|
||
## 实际用法（position 模块）
|
||
|
||
以岗位管理为例，使用 `basicModal` + `useModal` hook：
|
||
|
||
### 父组件（index.vue）
|
||
|
||
```vue
|
||
<!-- src/views/system/position/index.vue -->
|
||
<script setup>
|
||
import { nextTick, ref } from 'vue';
|
||
import editDialog from './edit.vue';
|
||
|
||
const positionId = ref(0);
|
||
const editVisible = ref(false);
|
||
const createModalRef = ref();
|
||
|
||
// 新增
|
||
const handleAdd = async () => {
|
||
positionId.value = 0;
|
||
editVisible.value = true;
|
||
await nextTick();
|
||
createModalRef.value.openModal();
|
||
};
|
||
|
||
// 编辑
|
||
async function handleEdit(record) {
|
||
positionId.value = record.id;
|
||
editVisible.value = true;
|
||
await nextTick();
|
||
createModalRef.value.openModal();
|
||
}
|
||
</script>
|
||
|
||
<template>
|
||
<editDialog
|
||
ref="createModalRef"
|
||
v-if="editVisible"
|
||
:positionId="positionId"
|
||
v-model:visible="editVisible"
|
||
@success="reloadTable('noRefresh')"
|
||
/>
|
||
</template>
|
||
```
|
||
|
||
### 编辑弹窗（edit.vue）
|
||
|
||
```vue
|
||
<!-- src/views/system/position/edit.vue -->
|
||
<template>
|
||
<basicModal
|
||
@register="modalRegister"
|
||
ref="modalRef"
|
||
class="basicModal basicFormModal"
|
||
@on-ok="handleSubmit"
|
||
@on-close="handleClose"
|
||
>
|
||
<template #default>
|
||
<n-form class="ls-form" ref="formRef" :model="formData" label-placement="left" label-width="85px">
|
||
<n-form-item
|
||
label="岗位名称"
|
||
path="name"
|
||
:rule="{ required: true, message: '请输入岗位名称', trigger: 'blur' }"
|
||
>
|
||
<n-input v-model:value="formData.name" placeholder="请输入岗位名称" clearable />
|
||
</n-form-item>
|
||
<n-form-item label="岗位状态" path="status">
|
||
<n-radio-group v-model:value="formData.status" name="status">
|
||
<n-radio :value="1">正常</n-radio>
|
||
<n-radio :value="2">停用</n-radio>
|
||
</n-radio-group>
|
||
</n-form-item>
|
||
<n-form-item label="排序" path="sort">
|
||
<n-input-number v-model:value="formData.sort" />
|
||
</n-form-item>
|
||
</n-form>
|
||
</template>
|
||
</basicModal>
|
||
</template>
|
||
|
||
<script lang="ts" setup>
|
||
import { getPositionDetail, positionAdd, positionUpdate } from '@/api/system/position';
|
||
import { onMounted, reactive, ref } from 'vue';
|
||
import { useMessage } from 'naive-ui';
|
||
import { useModal } from '@/components/Modal';
|
||
|
||
const emit = defineEmits(['success', 'update:visible']);
|
||
const formRef = ref();
|
||
const message = useMessage();
|
||
|
||
const formData = reactive({ id: '', name: '', status: 1, sort: 0 });
|
||
|
||
const props = defineProps({
|
||
visible: { type: Boolean, required: true, default: false },
|
||
positionId: { type: Number, required: true, default: 0 },
|
||
});
|
||
|
||
const [modalRegister, { openModal, setSubLoading }] = useModal({
|
||
title: props.positionId ? '编辑岗位' : '添加岗位',
|
||
subBtuText: '确定',
|
||
width: 600,
|
||
});
|
||
|
||
const handleSubmit = async () => {
|
||
formRef.value
|
||
.validate()
|
||
.then(async () => {
|
||
props.positionId ? await positionUpdate(formData) : await positionAdd(formData);
|
||
message.success('操作成功');
|
||
setSubLoading(false);
|
||
emit('update:visible', false);
|
||
emit('success');
|
||
})
|
||
.catch(() => {
|
||
setSubLoading(false);
|
||
});
|
||
};
|
||
|
||
const handleClose = () => {
|
||
emit('update:visible', false);
|
||
};
|
||
|
||
const setFormData = async () => {
|
||
const data = await getPositionDetail(props.positionId);
|
||
for (const key in formData) {
|
||
if (data[key] != null && data[key] != undefined) {
|
||
formData[key] = data[key];
|
||
}
|
||
}
|
||
};
|
||
|
||
onMounted(() => {
|
||
if (props.positionId) setFormData();
|
||
});
|
||
|
||
defineExpose({ openModal });
|
||
</script>
|
||
```
|
||
|
||
## 弹窗数据流
|
||
|
||
```
|
||
父组件点击编辑 → positionId = record.id → editVisible = true
|
||
↓
|
||
edit.vue onMounted → positionId != 0 → setFormData() → 获取详情填充表单
|
||
↓
|
||
用户修改 → submit → formRef.validate() → positionUpdate(formData)
|
||
↓
|
||
emit('success') → 父组件 reloadTable() → 表格刷新
|
||
```
|
||
|
||
## 确认弹窗
|
||
|
||
删除等危险操作使用 NaiveUI 的 `useDialog`：
|
||
|
||
```typescript
|
||
import { useMessage, useDialog } from 'naive-ui';
|
||
|
||
const message = useMessage();
|
||
const dialog = useDialog();
|
||
|
||
async function handleDelete(record) {
|
||
let ids = [];
|
||
if (!record) {
|
||
ids = rowKeys.value;
|
||
}
|
||
|
||
dialog.warning({
|
||
title: '提示',
|
||
content: '确定要删除？',
|
||
positiveText: '确定',
|
||
negativeText: '取消',
|
||
onPositiveClick: async () => {
|
||
record?.id ? await positionDelete(record.id) : await positionBatchDelete(ids);
|
||
message.success('删除成功');
|
||
reloadTable();
|
||
},
|
||
});
|
||
}
|
||
```
|
||
|
||
`dialog.warning()` 是 NaiveUI 的命令式对话框，返回 Promise，用户取消时不执行 `onPositiveClick` 回调。
|
||
|
||
## v-model:visible 双向绑定
|
||
|
||
弹窗使用 `v-model:visible` 实现父子组件双向绑定：
|
||
|
||
```vue
|
||
<!-- 父组件 -->
|
||
<editDialog v-model:visible="editVisible" />
|
||
|
||
<!-- 子组件 -->
|
||
<script setup>
|
||
const emit = defineEmits(['update:visible']);
|
||
const handleClose = () => { emit('update:visible', false); };
|
||
</script>
|
||
```
|
||
|
||
:::tip 温馨提示
|
||
弹窗组件通过 `defineAsyncComponent(() => import('./edit.vue'))` 懒加载，首屏不加载弹窗代码。`useModal` hook 提供 `openModal`、`closeModal`、`setSubLoading` 等方法。关闭弹窗时通过 `v-model:visible` 自动同步父子状态。消息提示使用 `useMessage()`，确认弹窗使用 `useDialog()`。
|
||
:::
|
||
|
||
## 总结
|
||
|
||
编辑弹窗使用 `basicModal`（基于 `n-modal`）+ `defineAsyncComponent` 懒加载，通过 `v-model:visible` 双向绑定显隐状态。父组件通过 `positionId` prop 传递编辑行 ID，子组件在 `onMounted` 中判断并加载详情数据。操作成功后 `emit('success')` 通知父组件刷新表格。消息提示使用 `useMessage()`，确认对话框使用 `useDialog()`。
