Returns the form owner of internals's target element.

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

role: null | string
shadowRoot: null | internal.ShadowRoot

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

validationMessage: string

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

Returns the ValidityState object for internals's target element.

willValidate: boolean

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

Methods

  • 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.

    Returns boolean

  • 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.

    Returns boolean

  • setFormValue(value: null | string | FormData | File, state?: null | string | FormData | File): 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.

    Parameters

    • value: null | string | FormData | File
    • Optional state: null | string | FormData | File

    Returns 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
