    });

Answer 1

if ($("#RegisterForm").valid()) {
    $("#RegisterForm").submit();
}

Answer 2

Why don't you use annotation to validate the fields? it's much easier and cleaner, you can do as below:

 public class MyModel
 {
     [Required(ErrorMessage = "Please enter the Email address")]
     public string Email { get; set; }
 }
