有没有办法使用像这样的东西？在使用 RenderAction 渲染的部分视图中？
在我的 ASP.NET MVC 2 Web 应用程序中，我使用 RenderAction 在我所说的网站的“flash message”区域中显示 HTML。我所说的闪光区域是指靠近顶部的突出显示区域，其中包含有关上一个请求的消息，例如 Hello <%: Html.DisplayTextFor(m => m.Username) %>当用户登录时。
我正在处理的一条闪现消息有点复杂。它需要向响应中添加一段 Javascript 代码，但我想按照书中的建议将 script 元素放置在结束 标记之前 < a href="http://oreilly.com/catalog/9780596802806/" rel="nofollow">高性能 JavaScript。
在正常视图中，我使用 script 元素放置在页面底部。不幸的是，如果我在使用 RenderAction 呈现的部分视图中尝试相同的操作，我会收到解析器错误“内容控件必须是内容页面或引用的嵌套母版页中的顶级控件”母版页”。
是否有类似
In my ASP.NET MVC 2 web application, I utilize RenderAction to display HTML in what I call the "flash message" area of the web site. By flash area, I mean a highlighted area near the top that contains a message about the previous request, such as Hello <%: Html.DisplayTextFor(m => m.Username) %> when the user logs in.
One flash message that I am working on is a bit more complex. It needs to add a block of Javascript code to the response, but I want to place the script element before the end </body> tag as recommended in the book High Performance JavaScript.
In a normal view, I use <asp:Content ContentPlaceHolderID="FlashScriptElements" runat="server"><script> ... </script></asp:Content> to place script elements at the bottom of the page. Unfortunately, if I attempt the same in a partial view that is rendered with RenderAction, I get the Parser Error "Content controls have to be top-level controls in a content page or a nested master page that references a master page".
Is there something like <asp:Content> that I can use in partial views which will insert the contents into the corresponding spot of the master page?

RenderAction 不支持
您可以做的是将所需的脚本添加到 HttpContextBase.Items 集合中的某个位置。然后在文档末尾之前的主页中检索注册的脚本并将其打印出来。
<asp:Content>is not supported with RenderAction because RenderAction is equivalent to having code that would execute your child action method, gathered the response, and then pasted it in the parent method's view.What you could do is to add the scripts that you need somewhere in to the
HttpContextBase.Itemscollection. Then in your master page right before the end of the document retrieve the registered scripts and print them out.
