Answer 1

You can't download the file directly via ajax.

You can put a link on the page with the URL to your file (returned from the ajax call) or another way is to use a hidden iframe and set the URL of the source of that iframe dynamically. This way you can download the file without refreshing the page.

Here is the code

$.ajax({
    url : "yourURL.php",
    type : "GET",
    success : function(data) {
        $("#iframeID").attr('src', 'downloadFileURL');
    }
});
