asp.net - 使用 ASP.NET MVC 3 Helpers 渲染带有标题属性的 span 标签

Question

可以添加 HTML title属性到输入标签，如下所示:

@Html.TextBoxFor(model => model.Name, new { title = "Customer name" })

是否有类似的静态文本助手？与@Html.DisplayFor(model => model.Name)我可以从模型属性渲染文本。如何添加 HTML 属性以便获得 span标签呈现如下:

<span title="Customer name">ABC</span>

自定义 html 帮助器可能是最巧妙的解决方案。

public static MvcHtmlString SpanFor<TModel, TProperty>(this HtmlHelper<TModel> helper, Expression<Func<TModel, TProperty>> expression, object htmlAttributes = null)
{
    var valueGetter = expression.Compile();
    var value = valueGetter(helper.ViewData.Model);

    var span = new TagBuilder("span");
    span.MergeAttributes(new RouteValueDictionary(htmlAttributes));
    if (value != null)
    {
        span.SetInnerText(value.ToString());
    }

    return MvcHtmlString.Create(span.ToString());
}

=>

@Html.SpanFor(model => model.Name, new { title = "Customer name" })
