MDN’s new design is in Beta! A sneak peek: https://blog.mozilla.org/opendesign/mdns-new-design-beta/

HTMLIFrameElement.download()

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 download() method of the HTMLIFrameElement interface downloads a specified URL, storing it at /sdcard/download.

Syntax

var instanceOfDOMRequest =
instanceOfHTMLIframeElement.download(url, options);

Returns

A DOMRequest for handling the download request. Its request.onsuccess handler handles the success case, and its request.onerror handler handles the failure case.

Parameters

url
The URL of the file to be downloaded.
options Optional
An options object allowing optional settings to be specified for the download. The available options are:
  • filename: The filename to save the downloaded file as. If this is not specified, the filename used will be the original filename, as specified in the url.
  • referrer: Specifies a referrer for the downloaded file. If this is not specified there will be no referrer.

Examples

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

var request = browser.download(fooURL, { filename: 'foo.bin' });

request.onsuccess = function() {
  console.log("File downladed");
}

request.onerror = function() {
  console.log("Download error");
}

Specification

Not part of any specification.
