# 页面视图开发

|
|
|
<!-- Copyright (c) 2021-2026 小蚂蚁云团队 版权所有 -->
|
|
|
|
:::tip 说明
|
|
页面视图位于 `src/views/` 目录,每个业务模块遵循 `index.vue`(列表页)+ `edit.vue`(编辑弹窗)+ `detail.vue`(详情弹窗)的标准模式,辅以 `columns.ts`(列定义)和 `querySchemas.ts`(搜索表单)配置文件。
|
|
:::
|
|
|
|
## 目录结构
|
|
|
|
```
|
|
src/views/
|
|
├── tool/
|
|
│ ├── example/
|
|
│ │ ├── index.vue # 案例列表页
|
|
│ │ ├── edit.vue # 案例编辑弹窗
|
|
│ │ ├── detail.vue # 案例详情弹窗
|
|
│ │ ├── columns.ts # 表格列定义
|
|

## 文件职责
|
|
|
|
| 文件 | 职责 | 说明 |
|
|
|------|------|------|
|
|
| `index.vue` | 列表页 | 搜索表单 + 工具栏 + BasicTable + 编辑弹窗引用 |
|
|
| `edit.vue` | 编辑弹窗 | n-dialog + n-form,懒加载 |
|
|
| `detail.vue` | 详情弹窗 | n-dialog 展示详情,懒加载 |
|
|
| `columns.ts` | 表格列定义 | 定义列 key、title、render 函数等 |
|
|
| `querySchemas.ts` | 搜索表单定义 | FormSchema 数组,定义搜索字段 |
|
|
|
|
## index.vue 列表页
|
|
|
|
以案例管理为例,完整结构如下:
|
|
|
|
```vue
|
|
<template>
|
|
<div>
|
|
<!-- 搜索表单卡片 -->
|
|
<n-card :bordered="false" class="pt-3 mb-3 proCard">
|
|
<BasicForm @register="register" @submit="handleSubmit" @reset="handleReset" />
|
|
</n-card>
|
|
|
|
<!-- 数据表格卡片 -->
|
|
<n-card :bordered="false" class="proCard">
|
|
<BasicTable
|
|
:columns="columns"
|
|
:request="loadDataTable"
|
|
:row-key="(row) => row.id"
|
|
ref="basicTableRef"
|
|
:actionColumn="actionColumn"
|
|
@update:checked-row-keys="onCheckedRow"
|
|
:auto-scroll-x="true"
|
|
>
|
|
<!-- 表格顶部工具栏 -->
|
|
<template #tableTitle>
|
|
<n-space>
|
|
<!-- 新增按钮 -->
|
|
<n-button type="primary" @click="handleAdd" v-perm="['sys:example:add']">
|
|
<template #icon>
|
|
<n-icon>
|
|
<PlusOutlined />
|
|
</n-icon>
|
|
</template>
|
|
添加案例
|
|
</n-button>
|
|
|
|
<!-- 批量删除按钮 -->
|
|
<n-button
|
|
type="error"
|
|
@click="handleDelete()"
|
|
:disabled="!rowKeys.length"
|

v-perm="['sys:example:batchDelete']"
|

|
|
<template #icon>
|
|
<n-icon>
|
|
<DeleteOutlined />
|
|
</n-icon>
|
|
</template>
|
|
批量删除
|
|
</n-button>

},
|

|
|
},
|
|
];
|
|
```
|
|
|
|
## 数据流
|
|
|
|
```
|
|
页面加载 → BasicForm 注册 → BasicTable request 触发 → loadDataTable → API → 渲染表格
|
|
用户搜索 → handleSubmit → 更新 formParams → reloadTable → 重新请求
|
|
用户新增 → handleAdd → currentId=0 → editVisible=true → edit.vue 加载 → 表单填写 → 提交
|
|
用户编辑 → handleEdit → currentId=id → editVisible=true → edit.vue 加载详情 → 修改 → 提交
|
|
用户删除 → dialog.warning → 确认 → API → reloadTable
|
|
```
|
|
|
|
:::tip 温馨提示
|
|
`columns.ts` 和 `querySchemas.ts` 独立为配置文件,便于维护和复用。`columns` 中的 `render` 函数使用 Vue 的 `h()` 创建虚拟 DOM,可实现任意复杂的自定义渲染。`querySchemas` 中的 `options` 硬编码或通过字典 API 动态获取。
|
|
:::
|
|
|
|
## 总结
|
|
|
|
页面视图遵循 `index.vue` + `edit.vue` + `detail.vue` + `columns.ts` + `querySchemas.ts` 标准模式。列表页使用 `BasicForm` 搜索 + `BasicTable` 展示数据 + `TableAction` 操作按钮,编辑弹窗使用 `import` 直接导入 + `useLockFn` 防重复提交。消息提示使用 NaiveUI 的 `useMessage()`,确认对话框使用 `useDialog()`。
