|
## Components
|
|
|
|
|
|
|
|
|
|
### SchemaComponentProvider
|
|
|
|
|

|
|
|
|
```tsx | pure
|
|
|
|
|
<SchemaComponentProvider>
|
|
|
|
|
<SchemaComponent schema={{}}/>
|
|
|
|
|
</SchemaComponentProvider>
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### SchemaComponentOptions
|
|
|
|
|
|
|
|
|
|
提供 SchemaComponent 所需的 scope 和 components,可以嵌套,当 `inherit={true}` 时,继承父级的 scope 和 components。
|
|
|
|
|
|
|
|
|
|
```tsx | pure
|
|
|
|
|
<SchemaComponentOptions scope={{}} components={{}}>
|
|
|
|
|
</SchemaComponentOptions>
|
|
|
|
|
|
|
|
|
|
<SchemaComponentOptions scope={{}} components={{}}>
|
|
|
|
|
{/* 继承父级的 scope 和 components */}
|
|
|
|
|
<SchemaComponentOptions inherit scope={{}} components={{}}>
|
|
|
|
|
</SchemaComponentOptions>
|
|
|
|
|
</SchemaComponentOptions>
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
例如将 useTranslation 的 t 附加给 scope
|
|
|
|
|
|
|
|
|
|
```tsx | pure
|
|
|
|
|
import { useTranslation } from 'react-i18next';

|
|
|
|
2022-01-25 00:18:34 +08:00
|
|
|
|
function TranslationProvider(props) {
|
|
|
|
|
const { t } = useTranslation();
|
|
|
|
|
return (
|
|
|
|
|
<SchemaComponentOptions inherit scope={{ t }}>
|
|
|
|
|
{ props.children }
|
|
|
|
|
</SchemaComponentOptions>
|
|
|
|
|
);
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|

|
|
|
|
### useSchemaComponentContext()
|
|
|
|
|
|
|
|
|
|
获取 SchemaComponent 的上下文
|
|
|
|
|
|
|
|
|
|
```ts
|
|
|
|
|
const { refresh, reset } = useSchemaComponentContext();
|
|
|
|
|
```
|
|
|
|

|
|
|
|
### useDesignable()
|
|
|
|
|
|
|
|
|
|
获取当前 schema 节点设计器的 API
|
|
|
|
|
|
|
|
|
|
```ts
|
|
|
|
|
const {
|
|
|
|
|
designable, // 是否可以配置
|
|
|
|
|
patch, // 更新当前节点配置
|
|
|
|
|
remove, // 移除当前节点
|
|
|
|
|
insertAdjacent, // 在某位置插入,四个位置:beforeBegin、afterBegin、beforeEnd、afterEnd
|
|
|
|
|
insertBeforeBegin, // 在当前节点的前面插入
|
|
|
|
|
insertAfterBegin, // 在当前节点的第一个子节点前面插入
|
|
|
|
|
insertBeforeEnd, // 在当前节点的最后一个子节点后面
|
|
|
|
|
insertAfterEnd, // 在当前节点的后面
|
|
|
|
|
} = useDesignable();
|
|
|
|
|
|
|
|
|
|
const schema = {
|
|
|
|
|
name: uid(),
|
|
|
|
|
'x-component': 'Hello',
|
|
|
|
|
};
|
|
|
|
|
|
|
|
|
|
// 在当前节点的前面插入
|
|
|
|
|
insertBeforeBegin(schema);
|
|
|
|
|
// 等同于
|
|
|
|
|
insertAdjacent('beforeBegin', schema);
|
|
|
|
|
|
|
|
|
|
// 在当前节点的第一个子节点前面插入
|
|
|
|
|
insertAfterBegin(schema);
|
|
|
|
|
// 等同于
|
|
|
|
|
insertAdjacent('afterBegin', schema);
|
|
|
|
|
|
|
|
|
|
// 在当前节点的最后一个子节点后面
|
|
|
|
|
insertBeforeEnd(schema);
|
|
|
|
|
// 等同于
|
|
|
|
|
insertAdjacent('beforeEnd', schema);
|
|
|
|
|
|
|
|
|
|
// 在当前节点的后面
|
|
|
|
|
insertAfterEnd(schema);
|
|
|
|
|
// 等同于
|
|
|
|
|
insertAdjacent('afterEnd', schema);
|

|
|
|
|
几个插入的位置:
|
|

|
```ts
|
|
|
|
|
{
|
|
|
|
|
properties: {
|
|
|
|
|
// beforeBegin 在当前节点的前面插入
|
|
|
|
|
node1: {
|
|
|
|
|
properties: {
|
|
|
|
|
// afterBegin 在当前节点的第一个子节点前面插入
|
|
|
|
|
// ...
|
|
|
|
|
// beforeEnd 在当前节点的最后一个子节点后面
|
|
|
|
|
},
|
|
|
|
|
},
|
|
|
|
|
// afterEnd 在当前节点的后面
