This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The getVolume() method of the HTMLIFrameElement gets the current volume of the browser <iframe>.


There are two versions of this method, a callback version:

var request = instanceOfHTMLIframeElement.getVolume();

and a Promise version:

instanceOfHTMLIframeElement.getVolume().then(function(volume) { ... });


  • Callback version: A DOMRequest that represents the get volume request. It has an onsuccess handler to handle the success case, and an onerror handler to handle the failure case. The volume value is available in the request.result property, and is a floating point number between 0 and 1.
  • Promise version: A Promise that resolves with the volume value — a floating point number between 0 and 1.




Callback version:

var browser = document.querySelector('iframe');

var request = browser.getVolume();

request.onsuccess = function() {
  console.log('The current browser volume is ' + request.result);

Promise version:

var browser = document.querySelector('iframe');

browser.getVolume().then(function(volume) {
  console.log('The current browser volume is ' + volume);
