JET Message

Description:

Displays a message. All oj-message elements in a page must have an oj-messages element as its parent.

<oj-message id="simpleMessage" message="[[messageData]]">
</oj-message>

Accessibility

The oj.ojMessage#message.sound property is an accessibility feature for playing a sound when a message is opened. This property defaults to "none", and can be enabled by setting it to "defaults" or by providing URL to an audio file of a format that the browser supports. An accessible application must provide a way for users to enable sound on a settings or preferences page. Some browsers will have auto-play disabled by default, enabling it may require adjusting the browser settings.

message.sound :string

Specifies the sound to be played when a message is opened. Sound is an accessibility feature required for low vision users who view a zoomed section of the UI. Because messages may be shown outside of the zoomed section, such users require sound to be played to notify of new messages.

This attribute can take a URL of the audio file for the custom sound to be played. The supported formats are mp3, wav and ogg. Browser support should also be considered while choosing the format of the audio file. Literal string values "defaults" and "none" can also be used for this attribute. If the value is set to "none", then the sound will be disabled. If the value is set to "defaults", then a default sound is played.

The default sound uses Web Audio APIs, which is not yet supported by some browsers, default sound will not be played in such browsers. Sound will not be played in browsers where auto play is not enabled. Some of the browsers do not allow auto play, while other browsers may provide a user preference to enable it.
