Constructor

HTMLOutputElement()

Instance properties

This interface also inherits properties from its parent, HTMLElement.

HTMLOutputElement.defaultValue

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

HTMLOutputElement.form Read only

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

HTMLOutputElement.htmlFor Read only

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.

HTMLOutputElement.labels Read only

A NodeList of <label> elements associated with the element.

HTMLOutputElement.name

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

HTMLOutputElement.type Read only

The string "output".

HTMLOutputElement.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 is false), or it satisfies its constraints.

HTMLOutputElement.validity Read only

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

HTMLOutputElement.value

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

HTMLOutputElement.willValidate Read only

Returns a boolean value that indicates whether the element is a candidate for constraint validation. Always false for HTMLOutputElement objects.

Instance methods

This interface also inherits methods from its parent, HTMLElement.

HTMLOutputElement.checkValidity()

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

HTMLOutputElement.reportValidity()

This method reports the problems with the constraints on the element, if any, to the user. If there are problems, fires an invalid event at the element, and returns false; if there are no problems, it returns true.

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.
