ASP.NET MVC 中实现局部更新 unobtrusive ajax

使用的是Linq to sql 对数据库进行通信的，使用表为product
首先我们要引用unobtrusive 这个js文件

<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.min.js")" type="text/javascript"></script>

第一步：先创建ProductControl
public class ProductController : Controller
{
TestDBDataContext context = new TestDBDataContext();
//
// GET: /Product/

public ActionResult Index()
{
var products = (from product in context.GetTable<Product>()
select product).ToList();
ViewData["products"] = products;
return View();
}

public ActionResult AddProduct(Product productModel)
{
productModel.CreateTime = DateTime.Now;
context.Products.InsertOnSubmit(productModel);
context.SubmitChanges();

return PartialView("ProductControl1", context.Products.ToList());
}

}

第二步：创建VIEW 

一个partial视图（ProductControl1.cshtml）用于显示Product信息，一个是index 页面添加产品，并且Render partial view(ProductControl1.cshtml)

Index页面代码

@model MvcApp.Product

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

<h2>Index</h2>
<fieldset>
<h1>Add product</h1>
@using(Ajax.BeginForm("AddProduct",new AjaxOptions{UpdateTargetId = "productList"}))
{
<div>@Html.LabelFor(m => m.Title)</div>
<div>@Html.EditorFor(m => m.Title)</div>
<div>@Html.LabelFor(m => m.Price)</div>
<div>@Html.EditorFor(m => m.Price)</div>
<p>
<input type="submit" value="Add Product" />
</p>
}
</fieldset>

<div id="productList">
@{Html.RenderPartial("ProductControl1",ViewData["products"]);}
</div>

partial视图：ProductControl1页面代码
@model IEnumerable<MvcApp.Product>
<table>
<tr>
<td>Title</td>
<td>Price</td>
<td>CreateTime</td>
</tr>
@foreach(var p in Model)
{
<tr>
<td>@p.Title</td>
<td>@p.Price</td>
<td>@p.CreateTime</td>
</tr>
}
</table>
