前臺程式碼：

var codes=new Array();
                $(".bottlecode").each(function(){
                    codes.push($(this).val());
                });
                 $.ajax({
                        type:"POST",
                        dataType:"json",
                        data:{
                            params:codes
                        },
                        url:"${ctx}/samplingmanage/preparationManage/ajaxEncode"
 
,

                        success:function(data){
                            var en=data.body.encodes;
                            for(var key in en){//遍歷從後臺獲取的map物件

                                console.log("value:"+en[key]);
