如何呈现Asp.Net MVC河套平原HTML链接? [英] How to render plain HTML links in Asp.Net MVC loop?
问题描述
我想呈现ASP.NET MVC HTML链接的列表。请注意,链接是绝对和外部以正在设计的网站。下面code工作:
I would like to render a list of HTML links in ASP.NET MVC. Note that the links are absolute and external to the website being designed. The following code works:
<% foreach (var item in Model) { %>
<tr>
<td>
<%= Html.Encode(item.Id) %>
</td>
<td>
<%= String.Format("<a href=\"{0}\">link</a>", item.Url) %>
</td>
</tr>
<% } %>
但我想知道如果它真的是正确的做法。我在这里缺少一些明显的MVC控制?
But I am wondering if it's really the right approach. Am I missing some obvious MVC control here?
推荐答案
您不会错过任何东西,但好的方法是创建的HtmlHelper扩展方法:
You are not missing anything but good approach is to create extender method on HtmlHelper:
public static class HtmlHelpers
{
public static string SimpleLink(this HtmlHelper html, string url, string text)
{
return String.Format("<a href=\"{0}\">{1}</a>", url, text);
}
}
那么你可以使用这样的:
then you can use it like this:
<tr>
<td>
<%= Html.Encode(item.Id) %>
</td>
<td>
<%= Html.SimpleLink(item.Url,item.Text) %>
</td>
</tr>
我忘了补充。为了使用整个应用此扩展的HtmlHelper您需要添加以下内容的网络配置文件:
[edit] I forgot to add. In order to use this HtmlHelper extender throughout application you need to add the following in the web config file:
<system.web>
<pages>
<namespaces>
<!-- leave rest as-is -->
<add namespace="theNamespaceWhereHtmlHelpersClassIs"/>
</namespaces>
</pages>
</system.web>
