Knockout + mvc 3 + Validation

Question

In the controller I would like to be able to get to the client validation rules of the model. I\'ve attached some attributes using data annotations and would like to be able

Answer 1

On the model use attributes validation that you like:

 public class ModelWithValidation
 {
    public int Id { get; set; }

    [Required]
    public string Name { get; set; }
 }

In mvc forms

@using( Html.BeginForm())
{    
     @Html.TextBoxFor(m => m.Name, new {data_bind = "value: name"})
     @Html.ValidationMessageFor(m => m.Name)
}

In jQuery test if form is valid onSubmit or in knockout save function call the next code to validate input. You must include jQuery.unobtrusive* and jQuery.validate* libraries. Don't forget to validate input on server side also!

var form = $("form");
form.removeData('validator');
form.removeData('unobtrusiveValidation');
$.validator.unobtrusive.parse(form);

$("form").valid() //true false
