HTMLIFrameElement.getMuted()

Non-standard
This feature is not on a current W3C standards track, but it is supported on the Firefox OS platform. Although implementations may change in the future and it is not supported widely across browsers, it is suitable for use in code dedicated to Firefox OS apps.

This API is available on Firefox OS for privileged or certified applications only.

The getMuted() method of the HTMLIFrameElement indicates whether the browser <iframe> is currently muted.

Syntax

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

var request = instanceOfHTMLIframeElement.getMuted();

and a Promise version:

instanceOfHTMLIframeElement.getMuted().then(function(muted) { ... });

Returns

  • Callback version: A DOMRequest that represents the get muted request. It has an onsuccess handler to handle the success case, and an onerror handler to handle the failure case. The muted value is available in the request.result property, and is a Boolean value — true means muted, and false means unmuted.
  • Promise version: A Promise that resolves with the muted value — a Boolean where true means muted, and false means unmuted.

Parameters

None.

Example

Callback version:

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

var request = browser.getMuted();

request.onsuccess = function() {
  if(request.result) {
    console.log('The browser is muted.');
  } else {
    console.log('The browser is unmuted.');
  }
}

Promise version:

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

browser.getMuted().then(function(muted) {
  if(muted) {
    console.log('The browser is muted.');
  } else {
    console.log('The browser is unmuted.');
  }
});
