Instance Members

htmlFor: DOMTokenList

A DOMTokenList reflecting the for HTML attribute, containing a list of IDs of other elements in the same document that contribute to (or otherwise affect) the calculated value.

An HTMLFormElement indicating the form associated with the control, reflecting the form HTML attribute if it is defined.

name: String

A DOMString reflecting the name HTML attribute, containing the name for the control that is submitted with form data.

type: String

The DOMString "output".

defaultValue: String

A DOMString representing the default value of the element, initially the empty string.

value: String

A DOMString representing the value of the contents of the elements. Behaves like the Node.textContent property.

willValidate: Bool

A Boolean indicating whether the element is a candidate for constraint validation.

validity: ValidityState

A ValidityState representing the validity states that this element is in.

validationMessage: String

A DOMString representing a localized message that describes the validation constraints that the control does not satisfy (if any). This is the empty string if the control is not a candidate for constraint validation (willValidate is false), or it satisfies its constraints.

labels: NodeList

A NodeList of label elements associated with the element.

checkValidity(): Bool

Checks the validity of the element and returns a Boolean holding the check result.

Returns
Bool
reportValidity(): Bool

Triggers an invalid event and evaluates its result. if the result is true, then the problems with the constraints of this element are reported to the user. When the problem is reported, the user agent may focus the element and change the scrolling position of the document or perform some other action that brings the element to the user's attention. User agents may report more than one constraint violation if this element suffers from multiple problems at once. If the element is not rendered, then the user agent may report the error for the running script instead of notifying the user.

Returns
Bool
setCustomValidity(error: String): Void

Sets a custom validity message for the element. If this message is not the empty string, then the element is suffering from a custom validity error, and does not validate.

Name Type
error String
