method
RadioField.LiveValidate
Add a server check that provides feedback while this field is being edited.
Arguments
| Argument | Type | Description |
|---|---|---|
value | LiveValidator[string] | A non-nil callback returning validation messages, or an error if the check could not run. It receives unfinished form input and must be read-only. |
Returns
A new field definition with this live validator appended. Keep the returned definition; the original field is unchanged.
RadioFieldHow it works
LiveValidate preserves existing live checks. It does not register a save rule; use Validate separately to enforce the rule when saving.
