Here's the code snippet:
```
var iframe = document.createElement('iframe');
document.body.appendChild(iframe);
var fn = () => {
	iframe.remove();
	console.log('error');
};
var doc = iframe.contentDocument;
doc.open();
doc.close();
iframe.addEventListener('load', fn, true);
iframe.src = "https://www.seattlesymphony.org/~/media/files/notes/schubert-sonata-21-b-flat.pdf";
```

`iframe.src` can be replaced with any `Content-Disposition: attachment`
