获取控制器MVC 4复选框值

本文介绍了获取控制器MVC 4复选框值的处理方法，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

我尝试从一个复选框列表中选中的复选框值没有任何成功，下面是code，我曾尝试：

I am trying to retrieve the checked checkbox value from a checkbox list without any success , below is the code which i have tried:

示范

[DisplayName("Gender")] public IList<SelectListItem> Gender { get; set; }

控制器

public ActionResult Index() { AssociateFormViewModel objStudentModel = new AssociateFormViewModel(); List<SelectListItem> genderNames = new List<SelectListItem>(); genderNames.Add(new SelectListItem { Text = "Male", Value = "1" }); genderNames.Add(new SelectListItem { Text = "Female", Value = "2" }); genderNames.Add(new SelectListItem { Text = "Prefer not to say", Value = "3" }); objStudentModel.Gender = genderNames; return PartialView("AssociateApplicationForm", objStudentModel); } [HttpPost] public ActionResult HandleFormSubmit(MembershipFormViewModel model) { //model not valid, do not save, but return current umbraco page if (ModelState.IsValid == false) { return CurrentUmbracoPage(); } string test = "Gender: " + model.Gender + Environment.NewLine; //getting null here return RedirectToCurrentUmbracoPage(); }

查看

@foreach (var names in @Model.Gender) { var checkBoxId = "chk" + names.Value; var tdId = "td" + names.Value; <table width="100%"> <tr > <td width="20px"> <input type="checkbox" id="@checkBoxId" class="chkclass" value="@names.Value" /> </td> <td id="@tdId" width="100px"> @names.Text </td> </tr> </table> }

在任何地方我得到的想法是错误的选中的复选框值在行动后未来空，又怎么能我限制用户只选择一个复选框，

Any ideas where i am getting it wrong the selected checkbox value is coming null in the post action, Also how can i limit the user to select only one check box,

任何帮助或建议将AP preciated。谢谢

Any help or suggestion will be appreciated . Thanks

推荐答案

分配一个名称，你的复选框：

assign a name to your checkbox:

<input name="gender" type="checkbox" id="@checkBoxId" class="chkclass" value="@names.Value" />

然后接受与参数名称的字符串数组性别

[HttpPost] public ActionResult HandleFormSubmit(string[] gender, MembershipFormViewModel model) { //model not valid, do not save, but return current umbraco page if (ModelState.IsValid == false) { return CurrentUmbracoPage(); } string test = "Gender: " + model.Gender + Environment.NewLine; //getting null here return RedirectToCurrentUmbracoPage(); }
