Download file from Ajax (sort of)

Question

I have this ajax call in my GSP:

$.ajax({
    url: \'${request.contextPath + \'/Ticket/passAll\'}\',
    type: \'POST\',
    data: data,
    success: functio

As far as I know, it's not possible to trigger file-downloads via AJAX. Instead you may do something like this (e.g. with jQuery):

function downloadComplete(){ hideSpinner();}
function downloadStart(){ showSpinner();}

function download(){
    downloadStart()
    var urlParams = data // or e.g. $(form).serialize() 
    var downloadUrl = "${request.contextPath}/Ticket/passAll?" + urlParams 
    $("#download-iframe").remove()
    $('
