推荐答案
让我们修改模型一点:
public class ItemViewModel
{
public string Id { get; set; }
public string Name { get; set; }
public bool Checked { get; set; }
}
,那么你可以有一个控制器:
then you could have a controller:
public class HomeController: Controller
{
public ActionResult Index()
{
// This action is used to render the form =>
// we should populate our model with some values
// which could obviously come from some data source
var model = new[]
{
new ItemViewModel { Id = "1", Checked = true, Name = "item 1" },
new ItemViewModel { Id = "2", Checked = false, Name = "item 2" },
new ItemViewModel { Id = "3", Checked = true, Name = "item 3" },
};
return View(model);
}
[HttpPost]
public ActionResult Index(IEnumerable<ItemViewModel> items)
{
// This action will be invoked when the form is submitted
// and here the view model will be properly bound and
// you will get a collection of all items with their
// corresponding id, name and whether they were checked or not
...
}
}
那么你将有一个相应的视图(〜/查看/主页/ Index.cshtml
),这将包含表单,允许用户检查/取消选中值:
then you would have a corresponding view (~/Views/Home/Index.cshtml
) which would contain the form allowing the user to check/uncheck values:
@model IEnumerable<AppName.Models.ItemViewModel>
@using (Html.BeginForm())
{
@Html.EditorForModel()
<input type="submit" value="OK" />
}
和最后编辑模板(〜/查看/主页/ EditorTemplates / ItemViewModel.cshtml
)
@model AppName.Models.ItemViewModel
// Those two hidden fields are just to persist the id and name
@Html.HiddenFor(x => x.Id)
@Html.HiddenFor(x => x.Name)
<div>
@Html.CheckBoxFor(x => x.Checked)
@Html.LabelFor(x => x.Checked, Model.Name)
</div>
