# 邻近位置插入
与 DOM 的 [insert adjacent](https://dom.spec.whatwg.org/#insert-adjacent) 概念相似Schema 也提供了 `dn.insertAdjacent()` 方法用于解决邻近位置的插入问题。
## 邻近位置
```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
},
}
```
## useDesignable()
获取当前 schema 节点设计器的 API
```ts
const {
designable, // 是否可以配置
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);
```
示例
```tsx
import React from 'react';
import { SchemaComponentProvider, SchemaComponent, useDesignable } from '@nocobase/client';
import { observer, Schema, useFieldSchema } from '@formily/react';
import { Button, Space } from 'antd';
import { uid } from '@formily/shared';
const Hello = observer((props) => {
const { insertAdjacent } = useDesignable();
const fieldSchema = useFieldSchema();
return (
<div>
<h1>{fieldSchema.name}</h1>
<Space>
<Button
onClick={() => {
insertAdjacent('beforeBegin', {
'x-component': 'Hello',
});
}}
>
before begin
</Button>
<Button
onClick={() => {
insertAdjacent('afterBegin', {
'x-component': 'Hello',
});
}}
>
after begin
</Button>
<Button
onClick={() => {
insertAdjacent('beforeEnd', {
'x-component': 'Hello',
});
}}
>
before end
</Button>
<Button
onClick={() => {
insertAdjacent('afterEnd', {
'x-component': 'Hello',
});
}}
>
after end
</Button>
</Space>
<div style={{ margin: 50 }}>{props.children}</div>
</div>
);
});
const Page = observer((props) => {
return <div>{props.children}</div>;
});
export default () => {
return (
<SchemaComponentProvider components={{ Page, Hello }}>
<SchemaComponent
schema={{
type: 'void',
name: 'page',
'x-component': 'Page',
properties: {
hello1: {
type: 'void',
'x-component': 'Hello',
},
},
}}
/>
</SchemaComponentProvider>
);
}
```
