将dropdownlist值传递给控制器

时间：2013-01-31 10:27:59

标签： c# asp.net-mvc html-select

我有下拉列表，显示数据库中的数据。我在下拉列表中获取数据库数据，但是在下拉列表中选择值后，我想要在控制器中传递所选值，然后我想显示该选定值的所有详细数据。但是单击“提交”按钮，下拉列表的选定值不会传递给控制器​​。

这是我的代码

控制器：SearchMDLNoController.cs 

using System;
using System.Collections.Generic;

using System.Web.Mvc;
using ApricaCRMEvent.Models.CRM.DataLayer;
using ApricaCRMEvent.Models.CRM.DatabaseEntities;

namespace ApricaCRMEvent.Controllers

    public class SearchMDLNoController : Controller
    {
        CRM_Doctor_Request mdlnoObj = new CRM_Doctor_Request();

        public ActionResult Index()
        {
            ViewData["MDLno"] = new SelectList(SearchMDLNoDL.getAllMDLno(), "Request_For_Id", "Request_For_Id");
            return View();
        }

        [HttpPost]
        public ActionResult Index(CRM_Doctor_Request model)
        {
            ViewData["MDLno"] = new SelectList(SearchMDLNoDL.getAllMDLno(), "Request_For_Id", "Request_For_Id");

            //CRM_Doctor_Request mdlnoObj = SearchMDLNoDL.getMDLData("GJ04_D023");
            //mdlnoObj = SearchMDLNoDL.getMDLData(model.Request_For_Id);
            return View();
        }
        public ActionResult getMDLNoDetails(string id)
        {
            mdlnoObj=SearchMDLNoDL.getMDLData(id);
            return View();
        }
        public ActionResult ListDoctors()
        {
            return View(mdlnoObj);
        }

    }
}

这是局部视图，在此视图中选择下拉值..将显示详细数据

通过在下拉列表中选择值并单击提交按钮值未通过。在Index.aspx我尝试了一些javascript代码，但它不起作用。

我在代码中改变了一些东西。现在这很有效。

试试这个：

$.getJSON("/SearchMDLNo/getMDLNoDetails",{id : mdlno}, function (data) {
         alert(data.Request_For_Id);
});

这应该对你有用

<script type="text/javascript">
        function TestFun() {
            var mdlno = $("#ddlMDLNo").val();
            $.ajax({
              type: 'POST',
              dataType: 'json',
              data: {id: mdlno},
              success: function(result){
                      alert('success');
              }
            });
        }
</script>

然后在你的控制器中改变它：

    [HttpPost]
    public ActionResult getMDLNoDetails(string id)
    {
        mdlnoObj=SearchMDLNoDL.getMDLData(id);
        return Json(true);
    }
