MDN Reference

Readonly form

form: HTMLFormElement

Returns the form owner of internals's target element.

MDN Reference

Readonly labels

labels: NodeList

Returns a NodeList of all the label elements that internals's target element is associated with.

MDN Reference

role

role: string

Readonly shadowRoot

shadowRoot: ShadowRoot

Returns the ShadowRoot for internals's target element, if the target element is a shadow host, or null otherwise.

MDN Reference

Readonly validationMessage

validationMessage: string

Returns the error message that would be shown to the user if internals's target element was to be checked for validity.

MDN Reference

Readonly validity

validity: ValidityState

Returns the ValidityState object for internals's target element.

MDN Reference

Readonly willValidate

willValidate: boolean

Returns true if internals's target element will be validated when the form is submitted; false otherwise.

MDN Reference

Methods

checkValidity

  • checkValidity(): boolean

  • Returns true if internals's target element has no validity problems; false otherwise. Fires an invalid event at the element in the latter case.

    MDN Reference

    Returns boolean

reportValidity

  • reportValidity(): boolean

  • Returns true if internals's target element has no validity problems; otherwise, returns false, fires an invalid event at the element, and (if the event isn't canceled) reports the problem to the user.

    MDN Reference

    Returns boolean

setFormValue

  • setFormValue(value, state?): void

  • Sets both the state and submission value of internals's target element to value.

    If value is null, the element won't participate in form submission.

    MDN Reference

    Parameters

    Returns void

setValidity

  • setValidity(flags?, message?, anchor?): void

  • Marks internals's target element as suffering from the constraints indicated by the flags argument, and sets the element's validation message to message. If anchor is specified, the user agent might use it to indicate problems with the constraints of internals's target element when the form owner is validated interactively or reportValidity() is called.

    Parameters

    Returns void
