Render span tag with title attribute with ASP.NET MVC 3 Helpers

问题

It's possible to add a HTML title attribute to an input tag like so:

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

Is there a similar helper for static text? With @Html.DisplayFor(model => model.Name) I can render the text from a model property. How can I add HTML attributes so that I get a span tag rendered like this:

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

回答1:

Custom html helper is probably the neatest solution.

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" })

回答2:

<span title="Customer name">@Model.Name</span>

回答3:

If you are using @HTML.DisplayFor(model=>model.CustomerName) It will render as text, It will not shows any tag inside the values.

If you want to bind the "DisplayFor" using span , Use the below tag,

<span id="CustomerName">@Html.DisplayFor(model=>model.CustomerName)</span>

回答4:

You use the below

<span title="Customer name">@Html.DisplayTextFor(m => m.CustomerName)</span>
