noHref property (area)

Browser support:

Sets or retrieves whether an area is a link.

The noHref is only an informational property for the author, indicating that a region has no associated link. It is simpler not to specify the href property.

The noHref property always returns false in Internet Explorer, until its value is set from JavaScript.

Syntax:

object.noHref;

You can find the related objects in the Supported by objects section below.

Possible values:
