must be returned instead. The target IDL attribute
must reflect the content attribute of the same name.
|
| DOMString | - formMethod
- The action IDL attribute must
reflect the content attribute of the same name, except that on getting, when the
content attribute is missing or its value is the empty string, the document's address
must be returned instead. The target IDL attribute
must reflect the content attribute of the same name.
|
| boolean | - formNoValidate

reflect the content attribute of the same name, except that on getting, when the
content attribute is missing or its value is the empty string, the document's address

|
| DOMString | - formTarget
- The action IDL attribute must
reflect the content attribute of the same name, except that on getting, when the

must reflect the content attribute of the same name.
|
| NodeList | - labels
- Labelable elements have a NodeList object
associated with them that represents the list of label elements, in tree
order, whose labeled control is the element in question. The labels IDL attribute of labelable elements, on getting, must return that
NodeList object.
|
| DOMString | - name
- The name IDL attribute must reflect
the name content attribute.
|
| DOMString | - type
- The type IDL attribute must
reflect the content attribute of the same name, limited to only known
values.
|
| DOMString | - validationMessage
- The validationMessage attribute must
return the empty string if the element is not a candidate for constraint validation
or if it is one but it satisfies its constraints; otherwise,
it must return a suitably localized message that the user agent would show the user if this were
the only form control with a validity constraint problem.
|
| ValidityState | - validity
- The validity attribute must return a
ValidityState object that represents the validity states of the element. This object is live, and the same object must be returned each time the element's
validity attribute is retrieved.
|
| DOMString | - value
- The value and menu IDL attributes must reflect the
content attributes of the same name.
|
| boolean | - willValidate
- The willValidate attribute must return
true if an element is a candidate for constraint validation, and false otherwise
(i.e. false if any conditions are barring it from
constraint validation).
|
| Operations |
|---|
| boolean | - checkValidity()
- When the checkValidity() method is
invoked, if the element is a candidate for constraint validation and does not satisfy its constraints, the user agent must fire a simple
event named invalid that is cancelable (but in this case
has no default action) at the element and return false.
|
| boolean | - reportValidity()
- When the reportValidity() method is
invoked, if the element is a candidate for constraint validation and does not satisfy its constraints, the user agent must: fire a simple
event named invalid that is cancelable at the element,
and if that event is not canceled, report the problems with the constraints of that element to the
user; then, return false.
|
| void | - setCustomValidity(DOMString error)
- The setCustomValidity(message), when invoked, must set the custom validity error
message to the value of the given message argument.
