Element: ariaBrailleRoleDescription property
The ariaBrailleRoleDescription property of the Element interface reflects the value of the aria-brailleroledescription attribute, which defines the ARIA braille role description of the element.
This property may be used to provide an abbreviated version of the aria-roledescription value.
It should only be used if aria-roledescription is present and in the rare case where it is too verbose for braille.
The aria-brailleroledescription contains additional information about when the property should be set.
Value
<string>- : The value is a string, an unconstrained value type, that is intended to be converted into braille.
Examples
Getting and setting ariaBrailleRoleDescription
This example shows how you can get and set the ariaBrailleRoleDescription property.
HTML
First we define an <article> element that would be use as a slide in a slideshow.
We set the aria-roledescription attribute to “slide”, and its braille contraction in aria-brailleroledescription to “sld”.
<article
id="article"
aria-roledescription="slide"
aria-brailleroledescription="sld"
aria-labelledby="slide1heading">
<h1 id="slide1heading">Welcome to my talk</h1>
</article>
<pre id="log"></pre>
#log {
height: 70px;
overflow: scroll;
padding: 0.5rem;
border: 1px solid black;
}
JavaScript
const logElement = document.querySelector("#log");
function log(text) {
logElement.innerText = `${logElement.innerText}${text}\n`;
logElement.scrollTop = logElement.scrollHeight;
}
To get the element’s role description we use the ariaBrailleRoleDescription property.
The code below first gets and then logs the value.
It then sets the braille role description to “sd” and logs the value again (for illustration only — in production code you would not set this value).
const article = document.getElementById("article");
log(article.ariaBrailleRoleDescription);
article.ariaBrailleRoleDescription = "sd";
log(article.ariaBrailleRoleDescription);
