原始 ActionLink 链接文本 [英] Raw ActionLink linkText

问题描述

我想把一个按钮作为 @ActionLink() 的文本，但我不能，因为它 HTML 转义了我的字符串......我找到了 @Html.Raw() 机制并尝试了 @ActionLink().ToHtmlString() 但不知道如何将其组合在一起...

I want to put a button as the text of an @ActionLink() but I can't because it HTML-escapes my string... I found the @Html.Raw() mechanism and have tried the @ActionLink().ToHtmlString() but can't figure out how to put it together...

我发现一篇文章，描述了为类似目的构建扩展，但它是讨厌去那么多麻烦......一定有一个简单的方法吗?

I found an article that describes building an extension for a similar purpose but it's eeky to go to that much trouble... there must be an easy way?

推荐答案

你可以写一个助手:

public static class HtmlExtensions
{
    public static IHtmlString MyActionLink(
        this HtmlHelper htmlHelper, 
        string linkText, 
        string action, 
        string controller,
        object routeValues,
        object htmlAttributes
    )
    {
        var urlHelper = new UrlHelper(htmlHelper.ViewContext.RequestContext);
        var anchor = new TagBuilder("a");
        anchor.InnerHtml = linkText;
        anchor.Attributes["href"] = urlHelper.Action(action, controller, routeValues);
        anchor.MergeAttributes(new RouteValueDictionary(htmlAttributes));
        return MvcHtmlString.Create(anchor.ToString());
    }
}

然后使用这个助手:

@Html.MyActionLink(
    "<span>Hello World</span>", 
    "foo", 
    "home",
    new { id = "123" },
    new { @class = "foo" }
)

哪个给定的默认路由会产生:

which given default routes would produce:

<a class="foo" href="/home/foo/123"><span>Hello World</span></a>
