mvc 下拉列表 DropDownList 两种绑定方式

前台

@Html.DropDownListFor(model=> model.lishudanweiid, ViewBag.DevNameList asIEnumerable<SelectListItem>, "请选择", new {@class = "form-control" })

后台

1绑定数据源 ：ViewBag.DevNameList  红色部分要与前台一致

  public void GetTielujuInfos()

        {

            List<Model.Sys_Station>seriesList = StationService.LoadEntities(u =>u.higherUpcode.Equals("A0000")).ToList(); ;

            //1.2将YzSeriesEntity的数据封装到SelectList中，制定要生成下拉框选项的value和text属性 

            SelectList selList1 = newSelectList(seriesList, "UnitCode", "UnitName");

            ViewBag.DevNameList = selList1;

        }

Id和text 同时拿到

<input type="hidden"name="lishudanwei" id="lishudanwei" />

$("#lishudanwei").val($("#lishudanweiidoption:selected").text());  

$("#text").val($("#id option:selected").text());

$("#id option:selected").val()

 

判断请选择

  if("请选择" == $("#leixingid option:selected").text()) {

 

                $.messager.alert('警告', '请选择类别!');

                return;

           }

 

另外一种下拉绑定适合多个共用

新增前台：

    页面：<inputclass="easyui-combobox" id="leixingid"

                                      name="leixingid"

                                      data-options="

                   url:'/Zhiqinshilileixing/GetQicaileibie',

                    valueField:'id',

                    textField:'name',

                    panelHeight:'auto'

                        " required="true">

提交获取值：  $("#leixingmingcheng").val($("#leixingid").combobox('getText'));

相同后台：

   public ActionResult GetQicaileibie()

       {

           var data = ZhiqinshilileixingService.LoadEntities(u => true);

           var d1 = from d in data

                     select new

                     {

                         d.id,

                         d.name

                     };

           return Json(d1);

       }

编辑

页面加载：

$('#leixingid').combobox({

                url:'/Zhiqinshilileixing/GetQicaileibie',

                valueField: 'id',

                textField: 'name',

           });

页面：<input id="leixingid" name="leixingid"value="@Model.leixingid" required="true" />

提交获取值：  $("#leixingmingcheng").val($("#leixingid").combobox('getText'));
