FontFaceSet: loading event

Note: This feature is available in Web Workers.

The loading event fires when the document begins loading fonts.

Syntax

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

addEventListener("loading", (event) => { })

onloading = (event) => { }

In the following example, when the font Ephesis starts to load, "Font is loading…" is printed to the console.

document.fonts.onloading = () => {
  console.log("Font is loading");
};

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