modal-organize
Development命令式弹窗的代码组织规范与最佳实践。 当用户问"弹窗怎么组织"、"弹窗放哪"、"弹窗目录结构"、"弹窗代码规范"、"新增弹窗怎么写"、"重构弹窗结构"时使用。 核心原则:Vue 组件 + openXxx.ts 打开函数作为"一对"放在一起,按业务归属就近放置。

命令式弹窗代码组织规范
什么时候用
当需要新增弹窗、重构弹窗结构、或询问弹窗代码应该放在哪里时使用。
核心原则
每个弹窗 = 一个文件夹 = Vue 组件 + openXxx.ts 打开函数
高内聚、易维护、按业务归属就近放置。
推荐结构:页面内部聚合
假设页面是 UserManagement,有新增、编辑、详情、分配角色等弹窗。
src/
├── views/
│ └── user-management/
│ ├── index.vue # 主页面,只调用 openXxx 函数
│ ├── modals/ # 该页面专属弹窗聚合目录
│ │ ├── add-edit-user/
│ │ │ ├── UserForm.vue # 表单组件(纯UI+逻辑)
│ │ │ └── openUserForm.ts # 打开新增/编辑弹窗的命令式函数
│ │ ├── user-detail/
│ │ │ ├── UserDetail.vue # 详情组件
│ │ │ └── openUserDetail.ts
│ │ ├── assign-role/
│ │ │ ├── AssignRole.vue
│ │ │ └── openAssignRole.ts
│ │ └── confirm-delete/
│ │ ├── ConfirmDelete.vue
│ │ └── openConfirmDelete.ts
│ └── hooks/ # 页面级通用 hooks(可选)
│ └── useUserActions.ts
文件内容示例
1. 打开函数(openUserForm.ts)
import { useModal } from '@newlifex/cube-vue/core/composables/useModal';
import UserForm from './UserForm.vue';
import type { UserFormData } from './UserForm.vue';
/**
* 打开新增用户弹窗
*/
export function openAddUser(): Promise<UserFormData | null> {
return new Promise((resolve) => {
const { openModal } = useModal();
openModal({
title: '新增用户',
width: '600px',
component: UserForm,
componentProps: { mode: 'add' },
onConfirm: async (data: UserFormData) => {
// 调用新增 API
await createUserApi(data);
resolve(data);
},
onCancel: () => resolve(null),
onClosed: () => resolve(null),
});
});
}
/**
* 打开编辑用户弹窗
*/
export function openEditUser(user: User): Promise<UserFormData | null> {
return new Promise((resolve) => {
const { openModal } = useModal();
openModal({
title: '编辑用户',
width: '600px',
component: UserForm,
componentProps: { mode: 'edit', modelValue: user },
componentEvents: {
'update:modelValue': (val: UserFormData) => { /* 可选:实时同步 */ },
},
onConfirm: async (data: UserFormData) => {
await updateUserApi(user.id, data);
resolve(data);
},
onCancel: () => resolve(null),
onClosed: () => resolve(null),
});
});
}
2. 表单组件(UserForm.vue)
<template>
<el-form :model="formData" label-width="80px">
<el-form-item label="用户名" prop="name">
<el-input v-model="formData.name" />
</el-form-item>
<el-form-item label="邮箱" prop="email">
<el-input v-model="formData.email" />
</el-form-item>
</el-form>
</template>
<script setup lang="ts">
import { computed } from 'vue';
export interface UserFormData {
name: string;
email: string;
}
const props = defineProps<{
mode: 'add' | 'edit';
modelValue?: Partial<UserFormData>;
}>();
const emit = defineEmits<{
'update:modelValue': [value: UserFormData];
}>();
const formData = computed<UserFormData>({
get: () => ({
name: props.modelValue?.name ?? '',
email: props.modelValue?.email ?? '',
}),
set: (val) => emit('update:modelValue', val),
});
</script>
3. 主页面调用(index.vue)
<script setup lang="ts">
import { openAddUser, openEditUser } from './modals/add-edit-user/openUserForm';
import { openConfirmDelete } from './modals/confirm-delete/openConfirmDelete';
/**
* 新增用户
*/
async function handleAdd() {
const result = await openAddUser();
if (result) {
// 新增成功,刷新列表
await fetchList();
}
}
/**
* 编辑用户
*/
async function handleEdit(row: User) {
const result = await openEditUser(row);
if (result) {
await fetchList();
}
}
/**
* 删除用户
*/
async function handleDelete(row: User) {
const confirmed = await openConfirmDelete(row);
if (confirmed) {
await deleteUserApi(row.id);
await fetchList();
}
}
</script>
为什么这样组织?
| 优势 | 说明 |
|---|---|
| 高内聚 | 弹窗的 UI(.vue)和调用入口(.ts)紧密耦合,修改一个弹窗只需在一个文件夹内完成 |
| 易定位 | 看到 openAddUser,直接在同级文件夹找 UserForm.vue,不用满项目搜索 |
| 按页面隔离 | 不同页面的弹窗互不干扰,删除页面直接连 modals/ 一起删除,无残留 |
| 按需复用 | 如果多个页面共用同一个弹窗(如确认删除),可以将其提升到 src/components/modals/ 公共区域 |
| 无全局污染 | 弹窗组件不会注册到全局,命令式调用函数也只是普通的 TS 导出,树摇友好 |
跨页面复用:提升到公共组件
当弹窗需要在多个页面使用时,将其提升为公共弹窗组件:
src/
├── components/
│ └── modals/ # 全局共享弹窗
│ ├── confirm-delete/
│ │ ├── ConfirmDelete.vue
│ │ └── openConfirmDelete.ts
│ └── import-excel/
│ ├── ImportExcel.vue
│ └── openImportExcel.ts
├── views/
│ └── user-management/
│ ├── index.vue
│ └── modals/ # 页面专属弹窗仍保留
│ └── add-edit-user/
│ ├── UserForm.vue
│ └── openUserForm.ts
调用时从公共路径导入即可:
import { openConfirmDelete } from '@/components/modals/confirm-delete/openConfirmDelete';
Promise 化 vs 回调式
两种调用风格都支持,根据场景选择:
Promise 化(推荐)
适合简单的确认/表单场景,调用方代码更简洁:
const result = await openAddUser();
if (result) {
// 处理成功逻辑
}
回调式
适合复杂场景(需要实时控制弹窗状态、loading 等):
const modal = openModal({
title: '新增',
component: UserForm,
onConfirm: async () => {
modal.setConfirmLoading(true);
try {
await save();
modal.close();
} finally {
modal.setConfirmLoading(false);
}
},
});
命名约定
| 项目 | 约定 | 示例 |
|---|---|---|
| 文件夹 | kebab-case,描述弹窗用途 | add-edit-user/、user-detail/ |
| Vue 组件 | PascalCase,描述内容 | UserForm.vue、UserDetail.vue |
| 打开函数文件 | open + 组件名(小驼峰) | openUserForm.ts |
| 打开函数名 | open + 用途(小驼峰) | openAddUser()、openEditUser() |
三种内容模式
useModal 支持三种内容模式,按复杂度选择:
| 模式 | 适用场景 | 示例 |
|---|---|---|
component | 复杂表单/交互,独立的 Vue 组件 | 新增/编辑用户表单 |
config | 简单表单,字段配置化即可 | 简单的新增弹窗 |
render | 完全自定义渲染逻辑 | 特殊的交互式弹窗 |
component 模式(最常用)
openModal({
title: '新增用户',
component: UserForm,
componentProps: { mode: 'add' },
onConfirm: async (data) => { /* ... */ },
});
config 模式(简单表单)
openModal({
title: '新增产品',
type: 'auto',
config: [
{ prop: 'name', label: '产品名称', required: true, component: 'input' },
{ prop: 'categoryId', label: '类别', component: 'select', props: { options: categoryOptions } },
],
modelValue: formData,
onSubmitSuccess: (data) => { /* ... */ },
});
支持的组件类型:input、select、textarea(input + type)、switch、inputNumber、radioGroup、checkboxGroup、datePicker
检查清单
新增/重构弹窗时,确认以下几点:
- ✅ 弹窗放在最近的业务归属目录下(页面内 modals/ 或 components/modals/)
- ✅ 每个弹窗有自己的文件夹,包含 .vue 和 openXxx.ts
- ✅ 主页面只导入 openXxx 函数,不直接引用弹窗组件
- ✅ 表单数据类型从 Vue 组件导出,打开函数复用类型
- ✅ 返回 Promise 的函数,取消/关闭时 resolve(null)
