_accProps 97

If you don’t specify an accessibility property for a document or an object, any values set in the

Accessibility panel are implemented.

After you specify an accessibility property, you can’t revert its value to a value set in the

Accessibility panel. However, you can set the property to its default value (

false for Boolean

values; empty strings for string values) by deleting the property from the

_accProps object, as

shown in the following example:

my_mc._accProps.silent = true; // set a property

// other code here

delete my_mc._accProps.silent; // revert to default value

The value of _accProps must be an object. This means that if no _accProps object already exists,

you must create one before you can assign clues to the properties of the

_accProps object.

if (_accProps == undefined) {

_accProps = new Object();

}

_accProps.name = "My movie";

Example

If you change an image and want to update its accessibility description, you can use the following

ActionScript code:

my_mc.gotoAndStop(2);

if (my_mc._accProps == undefined ) {

my_mc._accProps = new Object();

}

my_mc._accProps.name = "Photo of Mount Rushmore";

Accessibility.updateProperties();
