jQuery ajax - outputting files from an ajax request - ajax

Question

is it possible to output a file as a response from a ajax call?
i've wrote a function for outputting zip files using an ajax call, this is the code:
<script type="text/javascript">
$(document).ready(function () {
$(".ziplink").click(function (e) {
e.preventDefault();
var url = $(this).attr('href');
var spinner = $(this).parent().children(".spinnerbox");
spinner.show();
$.ajax({
url:url,
type:"GET",
dataType:"application/x-zip-compressed",
success:function (data) {
console.log('success');
spinner.hide();
},
error:function () {
console.log('ko');
spinner.hide();
}
});
});
});
</script>
now, from the firebug console everything is ook, but i dont have file output. what is missing?
Although this is fully functional in the non-ajax way (a simple link to the action), i'd like to have the spinner animation while server process the request.
thanx - LuKe

$(".ziplink").click(function (e) {
e.preventDefault();
var _self = $(this);
$('.spinner').show();
$.ajax({
type : 'HEAD',
url : _self.attr('href'),
complete : function(){
$('.spinner').hide();
var _tmp = $('<iframe />')
.attr('src', _self.attr('href'))
.hide()
.appendTo(_self)
setTimeout(function(){
_tmp.remove();
},5000);
}
});
});
