Javascript MVC-更改下拉选择上的标签-强类型视图

模型-Employee.cs

public class Employee
{
    public int id { get; set; }
    public string name { get; set; }
    public int age { get; set; }

    public List<Employee> lstEmployees { get; set; }
}

public ActionResult Index()
    {
        Employee emp = new Employee();
        emp.lstEmployees = new List<Employee>();
        emp.lstEmployees.Add(new Employee() { id = 1, name = "ABCD", age = 15 });
        emp.lstEmployees.Add(new Employee() { id = 2, name = "EFGH", age = 25 });
        emp.lstEmployees.Add(new Employee() { id = 3, name = "IJKL", age = 35 });

        ViewBag.EmpList = emp.lstEmployees;

        return View();
    }

公共类员工
{
公共int id{get；set；}
公共字符串名称{get；set；}
公共整数{get；set；}
公共列表{get；set；}
}

控制器-EmpController.cs

public class Employee
{
    public int id { get; set; }
    public string name { get; set; }
    public int age { get; set; }

    public List<Employee> lstEmployees { get; set; }
}

public ActionResult Index()
    {
        Employee emp = new Employee();
        emp.lstEmployees = new List<Employee>();
        emp.lstEmployees.Add(new Employee() { id = 1, name = "ABCD", age = 15 });
        emp.lstEmployees.Add(new Employee() { id = 2, name = "EFGH", age = 25 });
        emp.lstEmployees.Add(new Employee() { id = 3, name = "IJKL", age = 35 });

        ViewBag.EmpList = emp.lstEmployees;

        return View();
    }

public ActionResult Index（）
{
员工emp=新员工（）；
emp.lstmemployees=新列表（）；
添加（新员工（）{id=1，name=“ABCD”，age=15}）；
Add（newemployee（）{id=2，name=“EFGH”，age=25}）；
添加（newemployee（）{id=3，name=“IJKL”，age=35}）；
ViewBag.EmpList=emp.lstEmployees；
返回视图（）；
}

查看-Index.cshtml

@Html.DropDownListFor(m => m.id, new SelectList(ViewBag.EmpList, "id", "name"), new { onchange = "SelectedIndexChanged(this)" })


   <script type="text/javascript">
   function SelectedIndexChanged(p) {

   }
   </script>

@Html.DropDownListFor（m=>m.id，新建SelectList（ViewBag.EmpList，“id”，“name”），新建{onchange=“SelectedIndexChanged（this）”）
功能已选择索引已更改（p）{
}

我想在标签上显示年龄

@Html.LabelFor（model=>model.age）

更改下拉列表的选择时。

尝试此操作

<script type="text/javascript">
  function SelectedIndexChanged(element) {
     var optionSelected = $("option:selected", element);
     var selectedAge = $(optionSelected).attr('data-age');
     $('label[for="age"]').text(selectedAge);
  }
</script>
