Is a DOMString representing an enumerated property indicating alignment of the element's contents with respect to the surrounding context. The possible values are "left", "right", "justify", and "center".

HTMLObjectElement.archive

Is a DOMString that reflects the archive HTML attribute, containing a list of archives for resources for this object.

HTMLObjectElement.border

Is a DOMString that reflects the border HTML attribute, specifying the width of a border around the object.

HTMLObjectElement.code

Is a DOMString representing the name of an applet class file, containing either the applet's subclass, or the path to get to the class, including the class file itself.

HTMLObjectElement.codeBase

Is a DOMString that reflects the codebase HTML attribute, specifying the base path to use to resolve relative URIs.

HTMLObjectElement.codeType

Is a DOMString that reflects the codetype HTML attribute, specifying the content type of the data.

HTMLObjectElement.contentDocument Read only

Returns a Document representing the active document of the object element's nested browsing context, if any; otherwise null.

HTMLObjectElement.contentWindow Read only

Returns a WindowProxy representing the window proxy of the object element's nested browsing context, if any; otherwise null.

HTMLObjectElement.data

Returns a DOMString that reflects the data HTML attribute, specifying the address of a resource's data.

HTMLObjectElement.declare

Is a Boolean that reflects the declare HTML attribute, indicating that this is a declaration, not an instantiation, of the object.

HTMLObjectElement.form Read only

Retuns a HTMLFormElement representing the object element's form owner, or null if there isn't one.

HTMLObjectElement.height

Returns a DOMString that reflects the height HTML attribute, specifying the displayed height of the resource in CSS pixels.

HTMLObjectElement.hspace

Is a long representing the horizontal space in pixels around the control.

HTMLObjectElement.name

Returns a DOMString that reflects the name HTML attribute, specifying the name of the browsing context.

HTMLObjectElement.standby

Is a DOMString that reflects the standby HTML attribute, specifying a message to display while the object loads.

HTMLObjectElement.tabindex

Is a long representing the position of the element in the tabbing navigation order for the current document.

HTMLObjectElement.type

Is a DOMString that reflects the type HTML attribute, specifying the MIME type of the resource.

HTMLObjectElement.typeMustMatch

Is a Boolean that reflects the typemustmatch HTML attribute, indicating if the resource specified by data must only be played if it matches the type attribute.

HTMLObjectElement.useMap

Is a DOMString that reflects the usemap HTML attribute, specifying a <map> element to use.

HTMLObjectElement.validationMessage Read only

Returns a DOMString 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.

HTMLObjectElement.validity Read only

Returns a ValidityState with the validity states that this element is in.

HTMLObjectElement.vspace

Is a long representing the horizontal space in pixels around the control.

HTMLObjectElement.width

Is a DOMString that reflects the width HTML attribute, specifying the displayed width of the resource in CSS pixels.

HTMLObjectElement.willValidate Read only

Returns a Boolean that indicates whether the element is a candidate for constraint validation. Always false for HTMLObjectElement objects.

Methods

Inherits methods from its parent, HTMLElement.

HTMLObjectElement.checkValidity()

Retuns a Boolean that always is true, because object objects are never candidates for constraint validation.

HTMLObjectElement.setCustomValidity()

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.
