Downloading file from DataURL in JavaScript

From this string we get from DataURL, what's the best way to download this as a file?

So far what I got was using a basic window.open("myDataURL");, but I'm not able to change the file name in this way.

window.open('data:application/msword;base64,0M8R4KGxGuEAAAAAAAAAAAAAAAAAAAAA
             PgADAP7/CQAGAAAAAAAAAAAAAAACAAAANQAAAAAAA
             AAAEAAANwAAAAIAAAD+////AAAAADQAAABsAA/',
             '_blank','height=300,width=400');

I was wondering if there's any way to handle this data properly.

you can add a download attribute to the anchor element. sample:

<a download="abcd.zip" href="data:application/stream;base64,MIIDhTCCAvKg........">download</a>

Try this:

data:application/msword;fileName=test.doc;base64,0M8R4KGxGuEAAAAAAAAAAAAAAAAAAAAAPgADAP7/CQAGAAAAAAAAAAAAAAACAAAANQAAAAAAAAAAEAAANwAAAAIAAAD+////AAAAADQAAABsAA/

But this is just a guess from googling around and might be browser-dependent. The real answer to this is, you can't - See http://www.ietf.org/rfc/rfc2397 for reference, there's nothing in the specification to support a filename.
