FontFaceSet: loadingdone 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 loadingdone event fires when the document has loaded all fonts.

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

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

onloadingdone = (event) => {};

In the following example, when the font Ephesis has finished loading, "Font loading complete" is printed to the console.

document.fonts.onloadingdone = () => {
  console.log("Font loading complete");
};

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