Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The ratechange event is fired when the playback rate has changed.

This event is not cancelable and does not bubble.

Syntax

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

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

onratechange = (event) => { }

Event type

A generic Event.

Examples

These examples add an event listener for the HTMLMediaElement's ratechange event, then post a message when that event handler has reacted to the event firing.

Using addEventListener():

const video = document.querySelector("video");

video.addEventListener("ratechange", (event) => {
  console.log("The playback rate changed.");
});

Using the onratechange event handler property:

const video = document.querySelector("video");

video.onratechange = (event) => {
  console.log("The playback rate changed.");
};
