any appreciated

try this:

$('#exportbutton').click(function () {       var accounttype = $('#selectedaccounttype').val();        var fromdate = new date($('#fromdate').datepicker('getdate'));//get datepicker, selected date.       var todate = new date($('#todate').datepicker('getdate'));       var accountid = $('#selectedaccount').val();       var userid = $('#selecteduser').val();        var teamid = $('#selectedteam').val();       var id = "pdf";       $.post(            '@url.action("report", "reports")',             { id: id, selectedaccounttype: accounttype, fromdate: fromdate, todate: todate, selectedaccount: accountid, selecteduser: userid, selectedteam: teamid },             function (data) {       }); });
