HTMLInputElement: alt property

The alt property of the HTMLInputElement interface defines the textual label for the button for users and user agents who cannot use the image. It reflects the <input> element's alt attribute.

The alt property is valid for the image type only. It should be a non-empty string giving the label that would be appropriate for an equivalent button if the image was unavailable.

Value

A string.

Examples

js
const inputElement = document.getElementById("imageButton");
console.log(inputElement.alt);
inputElement.alt = "A much better description";
