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.
Properties
| Name | Type | Description |
|---|---|---|
autofocus |
Boolean |
Reflects the autofocus HTML attribute, indicating that the form control should have input focus when the page loads. |
challenge |
DOMString |
Reflects the challenge HTML attribute, containing a challenge string that is packaged with the submitted key. |
disabled |
Boolean |
Reflects the disabled HTML attribute, indicating that the control is not available for interaction. |
form |
readonly HTMLFormElement |
Indicates the control's form owner, reflecting the form HTML attribute if it is defined. |
keytype |
DOMString |
Reflects the keytype HTML attribute, containing the type of key used. |
labels Unimplemented (see bug 556743) |
readonly NodeList |
A list of label elements associated with this keygen element. |
name |
DOMString |
Reflects the name HTML attribute, containing the name for the control that is submitted with form data. |
type |
readonly DOMString |
Must be the value keygen. |
validationMessage |
readonly DOMString |
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. |
validity |
readonly ValidityState |
The validity states that this element is in. |
willValidate |
Boolean |
Always false because keygen objects are never candidates for constraint validation. |
Methods
| Name & Arguments | Return | Description |
|---|---|---|
checkValidity() |
Boolean |
Always returns true because keygen objects are never candidates for constraint validation. |
setCustomValidity(in DOMString error) |
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. |
