How to specify the name of file you create in javascript?

Question

I want to create a file in javascript. Before you say that it is impossible, go read this answer.

Here is what I have so far :

window.open("data:text/json;charset=utf-8," + escape("Ur String Object goes here"));

Now, my question is : How do I give a name to this file?

that's not a file. you're just passing around a STRING. a filename would only come into play if the user did a file->save as in that window — Marc B, Sep 22 '14 at 18:06

You don't; data URIs don't have a filename:

You can link to it and use the download attribute, though:

FWIW, you're not really creating a file here.
