JS 动态显示 获取下拉框的多个值

 <script type="text/javascript">
        function GetProcessVal(i, t) {
            document.getElementsByName("items[#index#].typeName")[i].value += t.value + ',';
        }
 </script>

后台代码：

static StringBuilder sbProcessingtype = null;

private void getProcessingtype()
        {
           if (null == sbProcessingtype)
            {
                sbProcessingtype= new StringBuilder();
               string str_Query = "select comoboxText  from  Bs_ComboBoxConfig  where comoboxID='15' order by comoboxValue asc";
                IList<string> list = objComboBoxConfigRepository.ExecuteSQLReturnStr(str_Query);

                sbProcessingtype.Append("<select  onchange=\"GetProcessVal({0},this)\"   name=\"items[#index#].Processingtype\"  > <option value=\"\"></option>");
               int count = list.Count;
               for (int i = 0; i < count; i++)
                {
                    sbProcessingtype.Append("<option value=\"" + list[i] + "\">" + list[i] + "</option>");
                }
            }
        }

调用 ：

 private string BindTable(IList<VOutProceManager> objList, bool isDeleted)
        {
            sbProcessingtype = null;
            getProcessingtype();//调用方法
            string strCalMethod = "";
            StringBuilder sb = new StringBuilder();
            int i = 0;
            string currentdate = DateTime.Now.ToString("yyyy-MM-dd");
            string PriceType = Convert.ToString(base.GetComboBoxConfig(15));
            foreach (VOutProceManager obj in objList)
            {
                sb.Append("<tr class=\"unitBox\">");
                if (isDeleted)
                    sb.Append("<td style='width:30px'  ><a class='btnDel' style='width:22px' target=\"ajaxTodo\" style=\"cursor:pointer\"  href=\"outProcessGL/OProcessRequisition/DelMaterialInfo?id=" + obj.Id + "&iscoper=" + obj.Isbom + "\" >删除</a></td>");
                else
                    sb.Append("");
                sb.Append("<input type=\"hidden\"   name=\"items[#index#].Id\"   submitName=\"items[" + i + "].Id\" value=\"" + obj.Id + "\" /> ");
                sb.Append("<input type=\"hidden\"   name=\"items[#index#].bomID\"   submitName=\"items[" + i + "].bomID\" value=\"" + obj.bomID + "\" /> ");
                sb.Append("<input type=\"hidden\"   name=\"items[#index#].Isbom\"   submitName=\"items[" + i + "].Isbom\" value=\"" + obj.Isbom + "\" /> ");
                sb.Append("<td  ><input class=\"textInput \"   size='15'   readonly=\"readonly\"  value=\"" + obj.mouldNo + "\"  > </td>");
                sb.Append("<td  ><input class=\"textInput \" size='9'   readonly=\"readonly\" name=\"items[#index#].partName\" submitName=\"items[" + i + "].partName\" value=\"" + obj.partName + "\"  > </td>");
                sb.Append("<td  ><input class=\"textInput \" size='3'   readonly=\"readonly\" name=\"items[#index#].drawingNo\"  submitName=\"items[" + i + "].drawingNo\"   value=\"" + obj.drawingNo + "\"  > </td>");
                sb.Append("<td  ><input class=\"textInput required number\" size='9'  name=\"items[#index#].qty\"  submitName=\"items[" + i + "].qty\" value=\"" + obj.qty + "\"  > </td>");
                sb.Append("<td  ><input class=\" textInput  \" size='15'    name=\"items[#index#].typeName\"  submitName=\"items[" + i + "].typeName\" value=\"" + obj.typeName + "\"  > ");
                sb.Append(string.Format(sbProcessingtype.ToString(), i) + " </td>");//调用sbProessingType
                sb.Append("</tr>");
                i++;
            }
            return sb.ToString();
        }
