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 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.
Browser compatibility
Note: Use of the Browser API requires a privileged app, and browser and/or embed-apps permissions, depending on what you want to do. See Using the Browser API for more details.
