.net - ASP.NET MVC HTML helper methods for new HTML5 input types

Question

HTML5 appears to support a new range of input fields for things such as:

• Numbers
• Email addresses
• Colors
• URLs
• Numeric range (via a slider)
• Dates
• Search boxes

Has anyone implemented HtmlHelper extension methods for ASP.NET MVC that generates these yet? It's possible to do this using an overload that accepts htmlAttributes, such as:

Html.TextBoxFor(model => model.Foo, new { type="number", min="0", max="100" })

But that's not as nice (or typesafe) as:

Html.NumericInputFor(model => model.Foo, min:0, max:100)

Just a heads up that many of these are now incorporated into MVC4 by using the DataType attribute.

As of this work item you can use:

public class MyModel 
{
    // Becomes <input type="number" ... >
    public int ID { get; set; }

    // Becomes <input type="url" ... >
    [DataType(DataType.Url)]
    public string WebSite { get; set; }

    // Becomes <input type="email" ... >
    [DataType(DataType.EmailAddress)]
    public string Email { get; set; }

    // Becomes <input type="tel" ... >
    [DataType(DataType.PhoneNumber)]
    public string PhoneNumber { get; set; }

    // Becomes <input type="datetime" ... >
    [DataType(DataType.DateTime)]
    public DateTime DateTime { get; set; }

    // Becomes <input type="date" ... >
    [DataType(DataType.Date)]
    public DateTime Date { get; set; }

    // Becomes <input type="time" ... >
    [DataType(DataType.Time)]
    public DateTime Time { get; set; }
}
