How to modify <head> elements programmatically?
Is there a way t开发者_开发百科o programmatically access and modify the <head> section of the page in ASP.NET MVC? I need to update the page's <meta> tags depending on which data the user is viewing on any given page.
You could use a content placeholder in the master page which you override in each view:
<head>
<title>
<asp:ContentPlaceHolder ID="TitleContent" runat="server" />
</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<asp:ContentPlaceHolder ID="Metas" runat="server" />
...
and in the view:
<asp:Content ID="IndexMetas" ContentPlaceHolderID="Metas" runat="server">
<meta name="keywords" content="some keywords specific to the view" />
</asp:Content>
Try:
<meta name="description" content="<%: Model.Meta %>" />
In ASP.NET 4.0 there are several new properties of the Page which you can use to set meta-tags directly like this:
Page.MetaKeywords = "asp.net,c#";
Page.MetaDescription = "This is my stackoverflow post";
You can read more about them here http://weblogs.asp.net/dotnetstories/archive/2010/03/23/asp-net-4-0-meta-tags-and-search-engine-optimisation.aspx
