@Html.RadioButtonFor in mvc

本文关键字:mvc in RadioButtonFor @Html | 更新日期: 2023-09-27 17:54:00

在我的应用程序中,我的模型包含一个字段id,在视图中,我需要选择一个带有单选按钮的id,并将选中的id发送回控制器。我该怎么做呢?我的观点如下,

@model IList<User>
@using (Html.BeginForm("SelectUser", "Users"))
{
    <ul>
        @for(int i=0;i<Model.Count(); ++i)
        {
            <li>
                <div>
                    @Html.RadioButtonFor(model => Model[i].id, "true", new { @id = "id" }) 
                    <label for="radio1">@Model[i].Name<span><span></span></span></label>
                </div>
            </li>
        }
    </ul>
    <input type="submit" value="OK">
}

@Html.RadioButtonFor in mvc

您需要更改您的模型来表示您想要编辑的内容。它需要包含所选User.Id的属性和要从

中选择的用户集合
public class SelectUserVM
{
  public int SelectedUser { get; set; } // assumes User.Id is typeof int
  public IEnumerable<User> AllUsers { get; set; }
}
视图

@model yourAssembly.SelectUserVM
@using(Html.BeginForm()) 
{
  foreach(var user in Model.AllUsers)
  {
    @Html.RadioButtonFor(m => m.SelectedUser, user.ID, new { id = user.ID })
    <label for="@user.ID">@user.Name</label>
  }
  <input type="submit" .. />
}
控制器

public ActionResult SelectUser()
{
  SelectUserVM model = new SelectUserVM();
  model.AllUsers = db.Users; // adjust to suit
  return View(model);
}
[HttpPost]
public ActionResult SelectUser(SelectUserVM model)
{
  int selectedUser = model.SelectedUser;
}
