The scroll event of the VisualViewport interface is fired when the visual viewport is scrolled.

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

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

onscroll = (event) => {};

A generic Event.

You can use the scroll event in an addEventListener method:

visualViewport.addEventListener("scroll", () => {
  // …
});

Or use the onscroll event handler property:

visualViewport.onscroll = () => {
  // …
};
