jquery ajax download

jquery ajax download

hi there, i am trying to pop up a download dialog after a link is clicked using jquery, i have tried this code but the download dialog is not popping up

  1. var options = {
                type: "GET",
                url: "FileHandler.ashx?download=1&filename=" + filename,
                data: "{filename:'" + filename + "'}",
                success: function(msg) {



  2.                   alert('success');
                },
                error: function(response)
                {
                    alert('error');
                }};
             $.ajax(options);





the reason why i want to use an ajax request is that i want to have a callback function after the download is successful or not. the request to the generic handler seems to be working and i can see response using firebug but again the download dialog is not showing up
