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='30px'  ><a class='btnDel' style='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();
        }
