我对 ASP.net MVC 世界还很陌生,我试图弄清楚如何呈现一组强类型为 View 模型的复选框。在网络表单中,我只会使用复选框列表控件,但我对 MVC 有点迷失。
我正在为婚礼策划业务构建一个简单的联系表格,并且需要将用户选择的任何复选框值传递给我的 Controller 。
表单复选框需要如下所示:
您的帮助将不胜感激。谢谢!
这是我到目前为止所拥有的。
Controller
[HttpPost]
public ActionResult Contact(ContactViewModel ContactVM)
{
if (!ModelState.IsValid)
{
return View(ContactVM);
}
else
{
//Send email logic
return RedirectToAction("ContactConfirm");
}
}
查看模型
public class ContactViewModel
{
[Required]
public string Name { get; set; }
[Required]
public string Phone { get; set; }
[Required]
[DataType(DataType.EmailAddress)]
public string Email { get; set; }
[Required]
public string Subject { get; set; }
public IEnumerable<SelectListItem> SubjectValues
{
get
{
return new[]
{
new SelectListItem { Value = "General Inquiry", Text = "General Inquiry" },
new SelectListItem { Value = "Full Wedding Package", Text = "Full Wedding Package" },
new SelectListItem { Value = "Day of Wedding", Text = "Day of Wedding" },
new SelectListItem { Value = "Hourly Consultation", Text = "Hourly Consultation" }
};
}
}
//Not sure what I should do for checkboxes...
}
看法
@model NBP.ViewModels.ContactViewModel
@{
ViewBag.Title = "Contact";
Layout = "~/Views/Shared/_Layout.cshtml";
}
@using (Html.BeginForm())
{
<div id="ContactContainer">
<div><span class="RequiredField">* </span>Your Name:</div>
<div>
@Html.TextBoxFor(model => model.Name)
</div>
<div><span class="RequiredField">* </span>Your Phone:</div>
<div>
@Html.TextBoxFor(model => model.Phone)
</div>
<div><span class="RequiredField">* </span>Your Email:</div>
<div>
@Html.TextBoxFor(model => model.Email)
</div>
<div>Subject:</div>
<div>
@Html.DropDownListFor(model => model.Subject, Model.SubjectValues)
</div>
<div>Vendor Assistance:</div>
<div>
<!-- CHECKBOXES HERE -->
</div>
<div>
<input id="btnSubmit" type="submit" value="Submit" />
</div>
</div>
}
最佳答案
您可以丰富您的 View 模型:
public class VendorAssistanceViewModel
{
public string Name { get; set; }
public bool Checked { get; set; }
}
public class ContactViewModel
{
public ContactViewModel()
{
VendorAssistances = new[]
{
new VendorAssistanceViewModel { Name = "DJ/BAND" },
new VendorAssistanceViewModel { Name = "Officiant" },
new VendorAssistanceViewModel { Name = "Florist" },
new VendorAssistanceViewModel { Name = "Photographer" },
new VendorAssistanceViewModel { Name = "Videographer" },
new VendorAssistanceViewModel { Name = "Transportation" },
}.ToList();
}
[Required]
public string Name { get; set; }
[Required]
public string Phone { get; set; }
[Required]
[DataType(DataType.EmailAddress)]
public string Email { get; set; }
[Required]
public string Subject { get; set; }
public IEnumerable<SelectListItem> SubjectValues
{
get
{
return new[]
{
new SelectListItem { Value = "General Inquiry", Text = "General Inquiry" },
new SelectListItem { Value = "Full Wedding Package", Text = "Full Wedding Package" },
new SelectListItem { Value = "Day of Wedding", Text = "Day of Wedding" },
new SelectListItem { Value = "Hourly Consultation", Text = "Hourly Consultation" }
};
}
}
public IList<VendorAssistanceViewModel> VendorAssistances { get; set; }
}
Controller :
public class HomeController : Controller
{
public ActionResult Index()
{
return View(new ContactViewModel());
}
[HttpPost]
public ActionResult Index(ContactViewModel model)
{
if (!ModelState.IsValid)
{
return View(model);
}
//Send email logic
return RedirectToAction("ContactConfirm");
}
}
看法:
@using (Html.BeginForm())
{
<div id="ContactContainer">
<div><span class="RequiredField">* </span>Your Name:</div>
<div>
@Html.TextBoxFor(model => model.Name)
</div>
<div><span class="RequiredField">* </span>Your Phone:</div>
<div>
@Html.TextBoxFor(model => model.Phone)
</div>
<div><span class="RequiredField">* </span>Your Email:</div>
<div>
@Html.TextBoxFor(model => model.Email)
</div>
<div>Subject:</div>
<div>
@Html.DropDownListFor(model => model.Subject, Model.SubjectValues)
</div>
<div>Vendor Assistance:</div>
<div>
@for (int i = 0; i < Model.VendorAssistances.Count; i++)
{
<div>
@Html.HiddenFor(x => x.VendorAssistances[i].Name)
@Html.CheckBoxFor(x => x.VendorAssistances[i].Checked)
@Html.LabelFor(x => x.VendorAssistances[i].Checked, Model.VendorAssistances[i].Name)
</div>
}
</div>
<div>
<input id="btnSubmit" type="submit" value="Submit" />
</div>
</div>
}
