最后book/index view需要更新去初始化jQuery的自动完成。要做的第一件事是使用@节标记，包括必要的JavaScript和CSS文件。接下来，以前创建的搜索文本框更新设置一个键的IDwordSearch。
最后，JavaScript代码添加在视图的底部去在搜索文本框上建立自动完成功能。此JavaScript是有意添加在view的底部，以确保完全呈现给用户，因为在用户的电脑上建立数据是一项工作，Javascript处理可能会“堵塞”页面加载。
（译者：先呈现数据再执行javascript，js不是像传统那样放在head标签里）
这取决于结果的数量。代码如下：
@model PagedList.IPagedList<MvcApplication.Models.Book>
@if (IsAjax)
{
Layout = null;
}
@section JavascriptAndCSS {
<link rel="stylesheet" href="@Url.Content(" rel="external nofollow" rel="external nofollow" ~/Content/jquery.autocomplete.css")" type="text/css" />
<script type="text/javascript" src="@Url.Content("~/Scripts/jquery.autocomplete.js")"></script>
<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.min.js")" type="text/javascript"></script>
}
<h2>@MvcApplication4.Resources.Resource1.BookIndexTitle</h2>
<p>
@Html.ActionLink("Create New", "Create")
</p>
<p>
Show:
@if (ViewBag.CurrentFilter != "")
{
@Ajax.ActionLink("All", "Index", new { sortOrder = ViewBag.CurrentSortOrder, Keyword = ViewBag.CurrentKeyword }, new AjaxOptions { UpdateTargetId = "main" })
}
else
{
@:All
}
