download a file generated by POST request with JQuery/javascript

[FlashRune]

Is it possible to show a download dialog after sending POST data to the server?Since I need many complex values "just" using a HTML form with method post won't work.Until now I used the GET method the following way:\[code\]$("form").submit(function() { window.location.href = 'http://stackoverflow.com/questions/12731254/upload.php?url='+$(".url").val()+'&host='+$(".host.clicked").attr("host"); return false;}\[/code\]which, with location.href will prompt me a nice download dialog, since upload.php returns headers for a file.The problem now is that I want to give the user the option to upload a file to the form, which would not work with the GET url method I'm using.So how can I show the download dialog after e.g. sending the data with AJAX and POST to the server?
