    {
       var selected_leave_type_id = jQuery("#leave_type").val()
       jQuery.post(
                "getUserLeaveQuota",
                { leave_type_id: selected_leave_type_id },
                function(data) {
                    alert(data);
                }

        );
    }

In controller i am makeing a query to get quota of loggined user, using

@user_leave_record = UserLeaveRecord.find(:first,:conditions => {:group_detail_id => params[:leave_type_id], :user_id => session[:user_id]})
