Yes.You can try with some hidden params.
$("#form").submit( function(eventObj) { $("<input />").attr("type", "hidden") .attr("name", "something") .attr("value", "something") .appendTo("#form"); return true; });
Try this:
$('#form').submit(function(eventObj) { $(this).append('<input type="hidden" name="field_name" value="value" /> '); return true;});
$('#form').append('<input type="text" value="'+yourValue+'" />');
