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;
}
