AutoFocus Plugin

Automatically focuses the first invalid field when form validation fails, improving keyboard navigation and accessibility.

Options

Option	Type	Default	Description
enabled	boolean	true	Enable or disable the plugin
onPrefocus	function	undefined	Called before focusing: ({ field, element }) => void

Playground

Submit the form with empty fields — the cursor jumps to the first invalid input automatically. The status line shows which field was focused.

Notes

• Focuses the first invalid field in the order they were defined in fields.
• Only fires on core.form.invalid — triggered by fv.validate(), not by fv.validateField().
• Use onPrefocus to scroll to the field, show a toast, or log analytics before focus occurs.
• Compatible with the Aria plugin — combining both gives full keyboard and screen reader accessibility.
• Field statuses are cleared at the start of each validate() call and re-tracked fresh.
