aria-pressed attribute | ariaPressed property (Internet Explorer)

[This documentation is preliminary and is subject to change.]

Sets or retrieves the pressed state of a button that can be toggled.

Syntax

<element aria-pressed="p" ... >

object.setAttribute("aria-pressed",value);var value = object.getAttribute("aria-pressed");

Property values

Type: String

The pressed state.

(true)

The element is down (button pressed).

(false)

The element is up.

(mixed)

The element indicates both pressed and unpressed states.

(undefined)

Default. The element state is unknown.

Remarks

Buttons with a defined ariaPressed state can be toggled. (When ariaPressed is true the button is down, when false it is up.) Simple command buttons do not need to define a ariaPressed state.

Note  For cross-browser compatibility, always use the WAI-ARIA attribute syntax to access and modify ARIA properties, for example object.setAttribute("aria-valuenow", newValue).
