VueFormHandlerformState
Provides you with the reactive state of the form, including validation, dirty and touched state, for the whole form or individual fields.
Return
| attribute | type | description |
|---|---|---|
| dirty | Record<string, boolean> | Object containing all the inputs that have been modified |
| errors | Record<string, string> | Object containing all the current field errors of the form |
| touched | Record<string, boolean> | Object containing all the inputs the users has interacted with |
| isDirty | boolean | True if there is any modified field on the form |
| isTouched | boolean | True if there has been any interaction with a form field |
| isValid | boolean | True if there are no form errors |
Rules
formState is read-only, so no assignments are expected. It is entirely reactive, so you can react on changes of the whole element and/or it's main attributes.
