The output element represents the result of a calculation performed
by the application, or the result of a user action.
| Properties |
|---|
| DOMString | - defaultValue
- The defaultValue IDL attribute, on
getting, must return the element's default value. On setting, the attribute must set the element's default
value, and, if the element's value mode flag is in
the mode default, set the element's
textContent IDL attribute as well.
|
| HTMLFormElement? | - form
- Reassociateable form-associated elements have a form
IDL attribute, which, on getting, must return the element's form owner, or null if
there isn't one.
|
| DOMSettableTokenList | - htmlFor
- The htmlFor IDL attribute must
reflect the for content attribute.
|
| 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 attribute must return the string
"output".
|
| 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 IDL attribute must act like the
element's textContent IDL attribute, except that on setting, in addition, before the
child nodes are changed, the element's value mode flag
must be set to value.
|
| 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.
