我正在上课,如下
public class UserRoleModel
{
public string Role { get; set; }
public bool UserRole { get; set; }
}
和public UserRoleModel [] UserRoles {get;组; }
我的控制器如下：
public ActionResult CreateUser()
{
UserDetailsModel model = new UserDetailsModel();
return View(model);
}
[HttpPost]
public ActionResult CreateUser(UserDetailsModel model)
{
return View(model);
}
在我看来我有
>@foreach (var item in Model.UserRoles)
{
name = "UserRoles"+ ".Value["+ i + "]";
id= "UserRoles" + "_Value[" + i++ + "]";
selected = item.UserRole ? "checked=\"checked\"" : "";
<p>
<input type="checkBox" name="@name" id="@id" @selected value="true" />
<label for="@id">@item.Role</label>
<input type="hidden" name="@name" value="false" />
</p>
}
解决方法
使用编辑器模板很好地实现了这些事情.他们也避免你在你的意见中写意大利面条代码.例：
模型：
public class UserDetailsModel
{
public IEnumerable<UserRoleModel> Roles { get; set; }
}
public class UserRoleModel
{
public string Role { get; set; }
public bool UserRole { get; set; }
}
控制器：
public class HomeController : Controller
{
public ActionResult Index()
{
return View(new UserDetailsModel
{
// Fill with some dummy stuff
Roles = Enumerable.Range(1,5).Select(x => new UserRoleModel
{
Role = "role " + x,UserRole = false
})
});
}
[HttpPost]
public ActionResult Index(UserDetailsModel model)
{
return View(model);
}
}
查看(〜/ Views / Home / Index.cshtml)：
@model AppName.Models.UserDetailsModel
@using (Html.BeginForm())
{
@Html.EditorFor(x => x.Roles)
<input type="submit" value="OK" />
}
编辑器模板(〜/ Views / Home / EditorTemplates / UserRoleModel.cshtml)：
@model AppName.Models.UserRoleModel @Html.CheckBoxFor(x => x.UserRole) @Html.LabelFor(x => x.Role,Model.Role) @Html.HiddenFor(x => x.Role)
现在这就是我所说的干净的东西.
