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>

答案 0 :(得分：0)
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;
}
}
});
}
});
