FontFaceSet: loadingerror event

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.

Note: This feature is available in Web Workers.

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

Use the event name in methods like addEventListener(), or set an event handler property.

addEventListener("loadingerror", (event) => {});

onloadingerror = (event) => {};

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");
})();
