asp.net-mvc – 为什么Partial View在MVC 5 Visual Studio 13中

查看/预订/ Index.cshtml：

<div id="bargainBook">
    @Ajax.ActionLink("Click here for the Bargain Book!","BargainBook",new AjaxOptions
    {
        UpdateTargetId = "bargainBook",InsertionMode = InsertionMode.Replace,HttpMethod = "GET"
    })
</div>

在BookController中：

public ActionResult BargainBook()
{
 var book = GetBargainBook();
 return PartialView("_BargainBook",book);
}

private Book GetBargainBook()
{
 return db.Books
     .OrderBy(b => b.Price)
     .First();

}

在_BargainBook.cshtml中：

@model BookDemo.Models.Book

<div>
<p>
    <strong>Book</strong>
    @Model.Name
</p>
<p>
    <strong>Price</strong>
    @String.Format("{0:F}",@Model.Price)
</p>
</div>
