I'm sure the answer to my question is somewhere in this website, but I couldn't manage to find an answer that fixes my problem.

I'm trying to download a $.ajax() or $.post() response content as CSV. I know these jquery functions don't download automatically despite a Content-Disposition: attachment; filename="name.csv" header, for security reasons.

But here are my constraints :

The response can be extremely large, depending on the filters the user set.
I don't want to clear the current page.
I can't create a server-side CSV file.
I'm not using <a> elements but <button>

Does anyone know how to do this in a clean and decently fast manner ?

You just have to prepare the download url and access it like an anchor, leave the rest to the serverside code. – Ionut Necula Oct 17 '18 at 12:05
Note this [specific answer](https://stackoverflow.com/a/29939024/519413) in the duplicate. For this to work you will need to create the file in-memory on the server and send it in the response. – Rory McCrossan Oct 17 '18 at 12:05
I forgot to tell I use `button`. My bad. anyone has a quickfix for that ? – Jean-Marc Zimmer Oct 17 '18 at 12:14
