Question

我有一个名为Associations的视图，它有一个下拉列表和一个按钮。当用户选择一个选项并按下提交时，我希望他们转到Association / {associationKey}。协会需要处理上下岗。

目前，使用下面的代码，当表单发布时，它会转到Association并显示正确的记录，但它不会将associationKey附加到URL。

所以我得到了：

http://localhost/Association

而不是：

http://localhost/Association/202

如果我手动导航到http://localhost/Association/202一切都运行正常，那么get和post都可以正常工作.... 我只想在帖子后的网址中输入密钥！

肯定有一些超级简单的事我做错了。相关代码如下。

谢谢！

协会观点：

<% Html.BeginForm("Association", "Staff", FormMethod.Post); %>
<%:Html.DropDownList("associationKey", new SelectList(Model.Associations.ToList(), "AssociationKey", "LegalName"))%>
<input type="submit" value="Edit The Selected Record" />
<% Html.EndForm(); %>

STAFF控制器：


        [AcceptVerbs(HttpVerbs.Get | HttpVerbs.Post)]
        public ActionResult Association(int associationKey)
        {
            return View("Association", new AssociationViewModel(associationKey));
        }

global.asax中：


        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
            routes.MapRoute("Default", "{action}", new { controller = "Staff", action = "Default" });
            routes.MapRoute("Associations", "Associations", new { controller = "Staff", action = "Associations" });
            routes.MapRoute("Association", "Association/{associationKey}", new { controller = "Staff", action = "Association" });
        }

ASSOCIATION视图模型：


    public class AssociationViewModel
    {

        public Repository db = new Repository();

        public Association Association {get; private set; }

        public List TelephoneTypes { get; private set; }

        public AssociationViewModel(int associationKey)
        {
            Association = db.AssociationById(associationKey);
            TelephoneTypes = db.ListTelephoneTypes().ToList();
        }

    }

Answer 1

我认为您应该将控制器操作分离为Get操作和POST操作，如下所示：

[AcceptVerbs(HttpVerbs.Get)]
public ActionResult Association(int associationKey)
{
    return View("Association", new AssociationViewModel(associationKey));
}

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Association(AssociationViewModel model)
{
    return RedirectToAction("Association", new {associationKey= model.associationKey});
}

MVC框架会自动将SelectList中的选定值绑定到模型（假设模型中有一个属性来保存选定的值）。从那里你只需要重定向到传递密钥的GET方法。

它正在做一个帖子而不是GET。这会将表单参数中的值放在url中。您可能希望使用javascript拦截表单提交，并使用location=..

将其转换为GET

<script type="text/javascript">
    $(function() { // requires jQuery
        $('form').submit( function() {
            // maybe do some validation to ensure a legal value chosen first?
            location.href = $(this).attr('action') + '/' + $(this).find('select').value();
            return false;  // cancel submit
        });
    });
</script>

<% Html.BeginForm("Association", "Staff", FormMethod.Post); %> 
<%:Html.DropDownList("associationKey", new SelectList(Model.Associations.ToList(), "AssociationKey", "LegalName"))%> 
<input type="submit" value="Edit The Selected Record" /> 
<% Html.EndForm(); %>

简单的MVC表单post和url路由问题....我希望
