HTMLKeygenElement
Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
Note: This page describes the Keygen Element interface as specified, not as currently implemented by Gecko. See bug 101019 for details and status.
The <keygen>
elements expose the HTMLKeygenElement
interface, which provides special properties and methods (beyond the regular element
object interface they also have available to them by inheritance) for manipulating the layout and presentation of keygen
elements.

. validationMessage
Read only-
A string 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
isfalse
), or it satisfies its constraints. validity
Read only-
A
ValidityState
object representing the validity states that this element is in. willValidate
-
A boolean value that is always false because
keygen
objects are never candidates for constraint validation.
Methods
checkValidity()
-
Always returns the boolean value
true
becauseHTMLKeygenElement
objects are never candidates for constraint validation. setCustomValidity()
-
Takes a string as parameter and sets it as the 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.
