# User Scripts 事件开发指南
|
||
|
||
本文档记录如何为表单设计器添加新的组件事件。
|
||
|
||
## 添加 Table Cell 事件的完整步骤
|
||
|
||
以添加 `cellFocus` 和 `cellBlur` 事件为例:
|
||
|
||
### 第一步:在 Events.ts 中添加枚举值
|
||
|
||
**文件路径**: `packages/types/form-designer/user-script/Events.ts`
|
||
|
||
在 `CompEventEnum` 枚举中添加新的事件类型:
|
||
|
||
```typescript
|
||
export enum CompEventEnum {
|
||
// ... 现有事件 ...
|
||
TABLE_CELL_CONTEXT_MENU = "cellContextMenu",
|
||
TABLE_CELL_FOCUS = "cellFocus", // 新增
|
||
TABLE_CELL_BLUR = "cellBlur", // 新增
|
||
TABLE_CELL_ALL_MOUNTED = "cellAllMounted",
|
||
// ...
|
||
}
|
||
```
|
||
|
||
### 第二步:在 Table.ts 中添加事件配置
|
||
|
||
**文件路径**: `packages/form-designer/src/config/user-script/eventInfo/comp/Table.ts`
|
||
|
||
在 `getTableCompEvents` 数组中添加事件配置:
|
||
|
||
```typescript
|
||
const getTableCompEvents: () => EventItemBO[] = () => [
|
||
// ... 现有事件配置 ...
|
||
{
|
||
name: CompEventEnum.TABLE_CELL_FOCUS,
|
||
label: t("userScript.events.component.tableCellFocus.label"),
|
||
desc: t("userScript.events.component.tableCellFocus.desc"),
|
||
},
|
||
{
|
||
name: CompEventEnum.TABLE_CELL_BLUR,
|
||
label: t("userScript.events.component.tableCellBlur.label"),
|
||
desc: t("userScript.events.component.tableCellBlur.desc"),
|
||
},
|
||
// ...
|
||
];
|
||
```
|
||
|
||
### 第三步:在 UseComp.ts 中添加触发函数
|
||
|
||
**文件路径**: `packages/form-designer/src/config/user-script/hooks/UseComp.ts`
|
||
|
||
1. 在 `useCompEvent` 函数内部添加处理函数:
|
||
|
||
```typescript
|
||
function handleTableCellFocus(...args: any[]) {
|
||
emitCompEvent(CompEventEnum.TABLE_CELL_FOCUS, args);
|
||
}
|
||
function handleTableCellBlur(...args: any[]) {
|
||
emitCompEvent(CompEventEnum.TABLE_CELL_BLUR, args);
|
||
}
|
||
```
|
||
|
||
2. 在 return 语句中导出函数:
|
||
|
||
```typescript
|
||
return {
|
||
// ... 现有导出 ...
|
||
handleTableCellMouseEnter,
|
||
handleTableCellMouseLeave,
|
||
handleTableCellFocus, // 新增
|
||
handleTableCellBlur, // 新增
|
||
handleTableCellChagne,
|
||
// ...
|
||
};
|
||
```
|
||
|
||
### 第四步:添加多语言配置
|
||
|
||
**文件路径**: `packages/form-designer/src/locales/model/UserScript.json`
|
||
|
||
在 `userScript.events.component` 节点下添加:
|
||
|
||
```json
|
||
{
|
||
"userScript": {
|
||
"events": {
|
||
"component": {
|
||
// ... 现有配置 ...
|
||
"tableCellFocus": {
|
||
"label": "单元格聚焦",
|
||
"desc": "表格单元格获得焦点时触发"
|
||
},
|
||
"tableCellBlur": {
|
||
"label": "单元格失焦",
|
||
"desc": "表格单元格失去焦点时触发"
|
||
}
|
||
}
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
## 通用步骤总结
|
||
|
||
为任何组件添加新事件的通用流程:
|
||
|
||
1. **定义事件类型** → `packages/types/form-designer/user-script/Events.ts` 中的 `CompEventEnum`
|
||
2. **配置事件信息** → `packages/form-designer/src/config/user-script/eventInfo/comp/` 下的对应组件文件
|
||
3. **实现触发函数** → `packages/form-designer/src/config/user-script/hooks/UseComp.ts`
|
||
4. **添加多语言** → `packages/form-designer/src/locales/model/UserScript.json`
|
||
|
||
## 注意事项
|
||
|
||
- 事件名称使用驼峰命名法(如 `cellFocus`)
|
||
- 枚举值使用大写下划线命名法(如 `TABLE_CELL_FOCUS`)
|
||
- 多语言 key 采用小驼峰命名(如 `tableCellFocus`)
|
||
- 如果事件是钩子函数(需要拦截/校验),需要设置 `isHook: true`
|
||
- 如果事件仅供内部使用,设置 `internal: true`
