The change event of the {{domxref("ScreenOrientation")}} interface fires when the orientation of the screen has changed, for example when a user rotates their mobile phone.

Syntax

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

onchange = (event) => { }

Event type

screen.orientation.addEventListener("change", (event) => {
  const type = event.target.type;
  const angle = event.target.angle;
  console.log(`ScreenOrientation change: ${type}, ${angle} degrees.`);
});
