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并将选定的id发回给控制器.我怎样才能做到这一点？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">
- }
解决方法
您需要更改模型以表示要编辑的内容.它需要包含所选User.Id的属性以及可供选择的用户集合
- 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" .. />
- }
调节器
- 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;
- }
