Playground

When a field is invalid, the input receives aria-invalid="true" and aria-describedby pointing to the error container. When valid, aria-invalid="false" and aria-describedby is removed. The status line below the form shows the current attribute values.

Notes

• Sets aria-invalid="true" on invalid elements and aria-invalid="false" on valid elements after each validation run.
• When used alongside the Message plugin, also sets aria-describedby on the field pointing to the error container, and role="alert" on the container so screen readers announce new errors automatically.
• Works without Message — only aria-invalid is set in that case.
• For radio/checkbox groups, aria-describedby is set on all elements in the group.
• Container id and role attributes are cleaned up when a field transitions back to valid.
