FontFaceSet: loadingerror event

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

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.

Syntax

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

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

onloadingerror = (event) => { }

Example

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

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

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