    HTMLIFrameElement.download()

    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 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.
