Question

我是MVC 4的新手。请问大家。请帮我解决以下问题。我有一个索引操作方法，我在其中设置分页后要显示的记录数。

索引操作方法如图所示

  public ActionResult Index(int? page){
        Provider providerList = new Provider();
        IList<Provider> providers = DAL.GetListofProviders.ToList();

        int pageSize = 5;
        int pageNumber = (page ?? 1);
        return View(providers.ToPagedList(pageNumber,pageSize));
    }

索引视图如下所示。

 @using PagedList;
 @using PagedList.Mvc;
 @model IPagedList<DEMO_JAN14.Models.Provider>
@{
    Layout = "~/Views/Shared/_Layout.cshtml";
 }
<head>
    <title>LIST OF PROVIDERS</title>
</head>
<body>
    <div class="container">
        <h1>Providers List</h1><br/>
        <a class="btn btn-primary col-sm-1" href="/Provider/Create">Create</a><br/>

        <table class="table table-bordered">
        <tr>
            <th>Provider Type</th>
        <th>First Name</th>
        <th>Last Name</th>
        <th>Certification</th>
        <th></th>
    </tr>
    <tbody data-bind="foreach:viewModel">
        <tr>
            <td class="col-lg-2" data-bind="text: ProviderType"></td>
            <td class="col-lg-2" data-bind="text: FirstName"></td>
            <td class="col-lg-2" data-bind="text: LastName"></td>
    <td><a class=" col-lg-2 btn btn-danger" id="del" onclick="" data-bind="attr: { href: '/Provider/Delete/'+ ProviderID }">Delete</a>
            </td>
        </tr>
     </tbody>
    </table>
    Page @(Model.PageCount<Model.PageNumber? 0 : Model.PageNumber) of @Model.PageCount
           @Html.PagedListPager( Model, page => Url.Action("Index", new { page }) )
    </div>   
  </body>

<script type="text/javascript" src="../../Scripts/knockout.mapping-latest.js"></script>
<script type="text/javascript">
    var data = @Html.Raw(Json.Encode(Model));
    var viewModel = ko.mapping.fromJS(data);
    ko.applyBindings(viewModel);
</script>

通过单击“创建”按钮，用户将被定向到另一个页面，在该页面中将数据输入表单并发布。

发布脚本如图所示。

   $("#Submit").on("click", function () {
       if (ValidatethisForm()) {
           $.ajax({
               type: "POST",
               url: "/Provider/Create",
               data: Provider
           });
        }
    });

在Create Action中，我错误地重定向到Index方法。

   public ActionResult Create(Provider provider)
    {
        try
        {
       DAL.InsertDataintoProviderTable(provider.ProviderType,provider.FirstName,provider.LastName);
            return RedirectToAction("Index(1)","Provider");
        }
        catch
        {
            return View();
        }
    }

请指引我正确的方向。谢谢。

编辑 ValidatethisForm方法

   function ValidatethisForm() {
    if (Provider.ProviderType() === "")
        return false;
    else if (Provider.FirstName() === "")
        return false;
    else if (Provider.LastName() === "")
        return false;
    else if (Provider.Certification() === "")
        return false
    else if (Provider.Specialization() === "")
        return false;
    else if (Provider.ContactNumber() === "")
        return false;
    else if (Provider.ContactEmail() === "")
        return false;
    else if (Provider.FacilityName() === "")
        return false;
    else
        return true;
}

创建页面的HTML

  @model DEMO_JAN14.Models.Provider

@{
   Layout = "~/Views/Shared/_Layout.cshtml";
 }

 <head>
   <title>CREATE PROVIDER</title>
</head>

问题是你用ajax调用页面，重定向不能像那样工作。您需要通过将URL传递给它来从JavaScript执行重定向。

在您的操作方法中，返回您要重定向到的操作的网址：

public ActionResult Create(Provider provider)
{
    try
    {
   DAL.InsertDataintoProviderTable(provider.ProviderType,provider.FirstName,provider.LastName);
        string url = Url.Action("Index", "Provider");
        return Json(new {url});
    }
    catch
    {
        return View();
    }
}

在JavaScript中抓取该网址并重定向到它：

   $("#Submit").on("click", function (e) {
       e.preventDefault();
       if (ValidatethisForm()) {
           $.ajax({
               type: "POST",
               url: "/Provider/Create",
               data: Provider,
               success: function(result) {
                   if (result.url) {
                       location.href = result.url;
                   }
               }
           });
        }
    });

从MVC 4中的另一个控制器重定向到操作（具有分页视图）
