  var blob = new Blob([content]);
  var evt = document.createEvent("HTMLEvents");
  evt.initEvent("click");
  $("", {
    download: filename,
    href: webkitURL.createObjectURL(blob)
  }).get(0).dispatchEvent(evt);
};

Usage:

downloadFile("foo.txt", "bar");

It uses jQuery and the webkit prefix, but both can be avoided.
