Here's the model, note that the Url attribute decorates the sole property on the model:

    using System.ComponentModel.DataAnnotations;

    namespace jQuery.Validation.Unobtrusive.Native.Demos.Models
    {
        public class UrlModel
        {
            [Url]
            public string Url { get; set; }
        }
    }
        

Here's the view (which uses the model):

    @model jQuery.Validation.Unobtrusive.Native.Demos.Models.UrlModel
    @using (Html.BeginForm())
    {
        <div class="row">
            @Html.LabelFor(x => x.Url, "Only urls can be entered:")
            @Html.TextBoxFor(x => x.Url, true)
        </div>

        <div class="row">
            <button type="submit" class="btn btn-default">Submit</button>
            <button type="reset" class="btn btn-info">Reset</button>
        </div>
    }
        

Here's the HTML that the view generates:

    <form action="/Demo/Url" method="post">
        <div class="row">
            <label for="Url">Only urls can be entered:</label>
            <input data-msg-url="The Url field is not a valid fully-qualified http, https, or ftp URL." data-rule-url="true" 
                id="Url" name="Url" type="text" value="" />
        </div>
        <div class="row">
            <button type="submit" class="btn btn-default">Submit</button>
            <button type="reset" class="btn btn-info">Reset</button>
        </div>
    </form>
        

Here's the JavaScript that initialises the validation:

  $("form").validate({
      submitHandler: function (form) {
          alert("This is a valid form!");
      }
  });
