jquery - Download file from different origin using POST request -

-

i'm trying prompt download request service different ui service (different domain).
trying using 

$.post(url, {param1: 'param1val', param2: 'param2val'})

the server returns csv file headers i receive response csv text , not sure how (if can) make being saved file.

clarification might help:
response server 

future(ok.chunked(rowenumerator.andthen(enumerator.eof))   .withheaders(("content-description", "file transfer"), ("content-transfer-encoding", "binary"), ("access-control-allow-origin","*"))   .as("text/csv").withheaders(content_disposition -> s"attachment; filename=resp.csv", content_type->"application/x-download"))

it seems problem $.post using ajax , looks impossible download file way.
solution dynamically creating form element on document body attributes correspond the data attempting send in $.post. 

var form = document.createelement("form"); form.setattribute(...); // method, action    // each data element post request var field = document.createelement("input"); field.setattribute(...); // type(hidden), key, value form.appendchild(field);    document.body.appendchild(form) form.submit()
