Form Actions

The form actions can be used only on the form instance.

• Validate the Form
• Validate Single Field
• Validation Errors

Validate the Form

The validate() action returns a promise.

The callback takes the Field Instance with its isValid prop, which is the validation state of the Form.

form.validate()
  .then(({ isValid }) => {
    ... // Use `isValid` to check the validation status
  });

The validation promise resolves the validated instance (Form or Field).

Validate Single Field

The validate(path) action get an optional field path in input and returns a promise.

The callback takes a boolean (isValid) with the validation state of the Field.

form.validate('email')
  .then(({ isValid }) => {
    ... // Use `isValid` to check the validation status
  });

The validation promise resolves the validated instance (Form or Field).

This is an alternative syntax to Actions - Validate a Field.

Validation Errors

The validate() method will not show errors by default.

If you need to show errors after a validation you do:

form.validate({ showErrors: true });

or on single field:

form.validate('email', { showErrors: true });
