Where can I use aria live?

aria-live is used when such live regions are available on the web page. Assistive technologies such as screen readers recognize the updated content with the aria-live property of the live region. The changes of the live region is intimated to the user depending on the politeness levels.

To maximize compatibility, add a redundant aria-live=”polite” when using this role. A status bar or area of the screen that provides an updated status of some kind. Screen reader users have a special command to read the current status. To maximize compatibility, add a redundant aria-live=”polite” when using this role.

How aria-live works. The aria-live attribute is added to specific HTML elements which we expect the content within them to change and we want the change to be communicated to users of assistive technology. The attribute has three potential values which control if and how changes are communicated.

An ARIA live region is a simple mechanism for notifying screen readers when content is updated on the page. When the update takes place within an ARIA live region, a screen reader is automatically notified (wherever its focus is at the time), and it conveys the updated content to the user.

The aria-invalid attribute is used to indicate that the value entered into an input field does not conform to the format expected by the application. This may include formats such as email addresses or telephone numbers. aria-invalid can also be used to indicate that a required field has not been filled in.

Adding aria-hidden=”true” to an element removes that element and all of its children from the accessibility tree. This can improve the experience for assistive technology users by hiding: purely decorative content, such as icons or images. duplicated content, such as repeated text.

Description. The aria-required attribute is used to indicate that user input is required on an element before a form can be submitted. This attribute can be used with any typical HTML form element; it is not limited to elements that have an ARIA role assigned.

Accessible Rich Internet Applications (ARIA) is a set of attributes that define ways to make web content and web applications (especially those developed with JavaScript) more accessible to people with disabilities. For instance, native elements have built-in keyboard accessibility, roles and states.

When setting aria-hidden=”true” to an element, all children will also be hidden. It is not possible to override this by setting aria-hidden=”false” to a child element.

Description. Adding aria-hidden=”true” to an element removes that element and all of its children from the accessibility tree. This can improve the experience for assistive technology users by hiding: purely decorative content, such as icons or images. duplicated content, such as repeated text.

These attributes are used to support the widget roles.

Edge does not support JAWS nor NVDA (or vice-versa, depending who you ask), so live regions will not work with either of those screen readers. Narrator works with Edge. It is not perfect, but it is coming along. Using your demo page with Edge and Narrator, the live region worked as expected.

Aria2 for Edge is an extension that could capture Edge download task to Aria2 and imports AriaNG as built-in management frontend. Filter priority Website -> File extension -> File size. Allow-list will be processed firstly when they are conflicted.

Because the live region has aria-live=”polite”, the screen reader will wait until the user pauses before announcing the update. Thus, moving down in the list and selecting another planet will not announce updates in the live region. Updates in the live region will only be announced for the planet finally chosen.

In Windows Eyes supports Live Regions since version 8.0 “for use outside of Browse Mode for Microsoft Internet Explorer and Mozilla Firefox”. NVDA added some basic support for Live Regions for Mozilla Firefox back in 2008 and was improved in 2010 and 2014. In 2015, basic support was also added for Internet Explorer (MSHTML).
