            $("#doWay").combobox('clear');
            var stepno = $("#badProduct").datagrid('getSelected').step;
            var data0 = [{text:"请选择",value:"-1"},{text:"让步接收",value:"3"},{text:"退货",value:"6"}];
            var data1 = [{text:"请选择",value:"-1"},{text:"返工",value:"2"},{text:"让步接收",value:"3"},{text:"报废",value:"4"}];
            var data2 = [{text:"请选择",value:"-1"},{text:"挑选",value:"1"},{text:"让步接收",value:"3"},{text:"报废",value:"4"}];

            var data4 = [{text:"请选择",value:"-1"},{text:"挑选",value:"1"},{text:"报废",value:"4"}];
            if(stepno==''){
               data=data0
            }
            if(stepno=='10'){
