HTMLIFrameElement.getManifest()

Non-standard
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 getManifest() method of the HTMLIFrameElement interface retrieves the manifest of an app loaded in the browser <iframe> and returns it as JSON.

Syntax

instanceOfHTMLIframeElement.getManifest().then(function(json) { ... });

Parameters

None.

Return value

A promise that resolves to a JSON object representation of the loaded app's manifest.

Examples

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

browser.addEventListener('mozbrowserloadend',function() {
  var request = browser.getManifest().then(function(json) {
    console.log(json);
  });
});

Specification

Not part of any specification.
