Get FileStreamResult using ajax asp.net core

Question

I had a function in controller named Export

    [HttpPost]
    [ActionName("Export")]
    public async Task<FileStreamResult> Export(int a)
    {
        var fileStream = new MemoryStream();
        var contentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";

        return new FileStreamResult(fileStream, contentType);
    }

I called this function from the view using ajax.

  $('#GetDetails').click(function () {

            $.ajax({
                url: '@Url.Action("Export", "ExportNow")',
                type: 'POST',
                data: {a:1},
                success: function (result) {
                    alert('Success.');
                },
                error: function (result) {
                    alert('Failed to Export.');
                }
            });
        });

how i can open the FileStreamResult returned from the Export function (download file). Anyone please help.

This works for me:

$('#GetDetails').click(function () {
    window.open('controlleraction/document?id=xx', '_blank');
});
