                $.ajax({  
                    type: "post",  
                    url: "JqueryCSMethodForm.aspx/GetNowDate",  
                    datatype: "json",  
                    contentType: "application/json; charset=utf-8",  
                    success: function(data) {  
                        $("input#showTime").val(eval('(' + data.d + ')')[0].nowtime);  
                    },  
                    error: function(XMLHttpRequest, textStatus, errorThrown) {  
                        alert(errorThrown);  
                    }  
                });

                    data:"{days:1}",  
                    datatype: "json",

                    success: function(data) {  
                        $("input#showTime").val(eval('(' + data.d + ')')[0].nowtime);
