HTMLAreaElement: alt property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The alt property of the HTMLAreaElement interface specifies the text of the hyperlink, defining the textual label for an image map's link. It reflects the <area> element's alt attribute.

The alt value must be text that, when presented with the alt text of the other <area> hyperlinks within the same <map>, along with the alt text of the <img> itself, provides the user with the same kind of choice as the hyperlink would when used without its text but with its shape applied to the image.

If the <area> is a link (contains an href property), the alt property value should be a non-empty string giving the label for the link that would be appropriate if the image were unavailable. The alt attribute for a link <area> can only be empty if there is another <area> element in the same <map> that points to the same resource and has a non-blank alt attribute.

Value

A string.

Examples

js
const areaElement = document.getElementById("imageArea");
console.log(areaElement.alt);
areaElement.alt = "A much better link description";
