    Readonlyform

    form: HTMLFormElement

    Returns the form owner of internals's target element.

    MDN Reference

    Readonlylabels

    labels: NodeList

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

    MDN Reference

    role

    role: string

    ReadonlyshadowRoot

    shadowRoot: ShadowRoot

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

    MDN Reference

    Readonlystates

    states: CustomStateSet

    MDN Reference

    ReadonlyvalidationMessage

    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

    Readonlyvalidity

    validity: ValidityState

    Returns the ValidityState object for internals's target element.

    MDN Reference

    ReadonlywillValidate

    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.

      MDN Reference

      Parameters

      Returns void
