FontFaceSet.onloadingerror

The onloadingerror EventHandler of the FontFaceSet interface processes loadingerror events.

The loadingerror event fires when fonts have finished loading, but some or all fonts have failed to load.

Syntax

FontFaceSet.onloadingerror = function;
FontFaceSet.addEventListener('loadingerror', function);

Example

In the following example, if the font Ephesis fails to load, "Font loading error" is printed to the console.

document.fonts.onloadingerror = () => {
  console.log('Font loading error');
}

(async () => {
  await document.fonts.load("16px Ephesis");
})();
