XUL Widgets: Attributes, Properties, and Methods

The following list describes the inventory of attributes, properties, and methods used by the XUL elements that are accessible from JavaScript code.

Tip

Although all JavaScript-managed attributes are accessed as strings, this glossary adds data types to provide guidance if the string value should represent a specific type. Examples of these types include Boolean, integer, and the name of a required interface. Properties without such qualifiers are presumed to be strings whose context is set by the application or by a specific interface design (e.g., the “ID” of widget). For ease of reference and to distinguish them from their data types, attribute, property, and method names are set in boldface font.

nsIAccessible accessible

The accessible property is available on all elements that inherit from the nsIAccessible interface. The interface provides assistive technology services similar to those of the Accessibility Toolkit (ATK) and Microsoft Active Accessibility (MSAA).

char accessKey

The character used as a keyboard accelerator; when coupled with an operating-system-specific keyboard combination, it triggers the control actuation.

boolean afterselected

When assigned to a tab, returns true if the tab is immediately after the currently selected tab.

align

Sets the alignment characteristics of the button in a manner consistent with all box containers. Interpretation of the align attribute is subject to the dir attribute:

"start"
