# useNumberField
|
||
|
|
|
||
|
|
`useNumberField()` reads the context provided by `NumberFieldRoot`. Use it inside custom field
|
||
|
|
parts that need the canonical value, draft, state attributes, ARIA attributes, or actions.
|
||
|
|
|
||
|
|
It throws when called outside a `NumberFieldRoot` subtree.
|
||
|
|
|
||
|
|
```ts
|
||
|
|
import { useNumberField } from '@open-pencil/vue'
|
||
|
|
|
||
|
|
const field = useNumberField()
|
||
|
|
field.actions.startEdit()
|
||
|
|
```
|
||
|
|
|
||
|
|
See [NumberField](../components/number-field) for the complete context and anatomy.
