# 页面视图开发

:::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）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

## 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 | el-dialog + el-form，懒加载 |
| `columns.ts` | 表格列定义 | 定义列 prop、label、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

以岗位管理为例，完整结构如下：

## 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 → positionId=0 → editVisible=true → edit.vue 加载 → 表单填写 → 提交
用户编辑 → handleEdit → positionId=id → editVisible=true → edit.vue 加载详情 → 修改 → 提交
用户删除 → confirm → API → reloadTable
```

## columns.ts

```typescript
// src/views/system/position/columns.ts
import { h } from 'vue';
import { ElTag } from 'element-plus';

export const columns = [
  {
    type: 'selection',
  },
  {
    label: 'ID',
    prop: 'id',
    fixed: 'left',
    width: 50,
  },
  {
    label: '岗位名称',
    prop: 'name',
    minWidth: 100,
  },
  {
    label: '岗位状态',
    prop: 'status',
    minWidth: 100,
    render(record) {
      return h(
        ElTag,
        {
          type: record.row.status == 1 ? 'success' : 'danger',
        },
        {
          default: () => (record.row.status == 1 ? '正常' : '停用'),
        },
      );
    },
  },
  {
    label: '排序',
    prop: 'sort',
    minWidth: 100,
  },
  {
    label: '创建人',
    prop: 'createUser',
    minWidth: 100,
  },
  {
    label: '创建时间',
    prop: 'createTime',
    width: 180,
  },
];
```

## querySchemas.ts

```typescript
// src/views/system/position/querySchemas.ts
import { FormSchema } from '@/components/Form/index';
export const schemas: FormSchema[] = [
  {
    field: 'name',
    component: 'Input',
    label: '岗位名称',
    componentProps: {
      placeholder: '请输入岗位名称',
    },
  },
  {
    field: 'status',
    component: 'Select',
    label: '状态',
    componentProps: {
      placeholder: '请选择状态',
      clearable: true,
      options: [
        {
          label: '正常',
          value: '1',
        },
        {
          label: '禁用',
          value: '2',
        },
      ],
    },
  },
];
```

:::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` + `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 `defineAsyncComponent` 懒加载 + `useLockFn` 防重复提交。数据流清晰：搜索更新参数 → 刷新表格，操作成功 → emit 事件 → 刷新表格。
