MVC控制器获得“复选框列表”的值

本文介绍了MVC控制器获得“复选框列表”的值的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我在这里可能是个白痴，但在获取是否已选中/未选中复选框的值方面遇到问题。这是到目前为止我得到的：

I'm probably a idiot here but I'm having problems getting the value of whether or not a checkbox is checked/selected or not. Here's what I've got so far:

在我的模型中：

public IEnumerable<SelectListItem> Insurers { get { var list = new List<SelectListItem>(); string zInsurersList = "Age UK,Be Wiser,Call Connection,Churchill,Sainsbury's,Direct Line,Hastings Direct,LV=,Nationwide,RIAS,Swinton"; string[] zInsurers = zInsurersList.Split(','); foreach (string aInsurer in zInsurers) { list.Add(new SelectListItem() { Text = aInsurer, Value = aInsurer, Selected=false}); } return list; } } }

我的观点：

@foreach (var insurer in @Model.Insurers) { var zInsurer = insurer.Text; var zValue = insurer.Value; <tr> <td style="width: 120px; height: 35px;"><span id="@zInsurer">@zInsurer</span></td> <td style="width: 40px; height: 35px;"><input id="@zInsurer" type="checkbox" name="@zInsurer"></td> </tr> }

所以在我的控制器中，我试图循环列表并获取值用户是否选择了以下选项：

So in my controller I'm trying to loop the list and get the value of whether or not the user has selected the option:

foreach (var item in model.Insurers) { //if (item.GetType() == typeof(CheckBox)) //string controlVal = ((SelectListItem)item).Selected.ToString(); zInsurers = zInsurers + item.Text + " " + ((SelectListItem)item).Selected.ToString() + "<br/>"; }

但该值始终返回false。

But the value always returns false.

有人可以花点时间强调我的愚蠢吗？

Could someone spare a few mins to highlight my stupidity please?

谢谢

推荐答案

有很多方法可以做到这一点。我通常在模型中添加 String Array 来收集选定的值。

There are a lot of ways to do it. I normally add String Array in model to collect selected values.

public string[] SelectedInsurers { get; set; } <input type="checkbox" name="SelectedInsurers" value="@insurer.Value" />

这是示例代码-

public class MyModel { public string[] SelectedInsurers { get; set; } public IEnumerable<SelectListItem> Insurers { get { var list = new List<SelectListItem>(); string zInsurersList = "Age UK,Be Wiser,Call Connection,Churchill,Sainsbury's,Direct Line,Hastings Direct,LV=,Nationwide,RIAS,Swinton"; string[] zInsurers = zInsurersList.Split(','); foreach (string aInsurer in zInsurers) { list.Add(new SelectListItem { Text = aInsurer, Value = aInsurer, Selected = false }); } return list; } } }

操作方法

Action Methods

public ActionResult Index() { return View(new MyModel()); } [HttpPost] public ActionResult Index(MyModel model) { return View(); }

查看

View

@using (Html.BeginForm()) { foreach (var insurer in @Model.Insurers) { <input type="checkbox" name="SelectedInsurers" value="@insurer.Value" /> @insurer.Text<br/> } <input type="submit" value="Post Back" /> }

结果
