Cause form validation on an Asp.net link mvc 5

Question

Good afternoon, everyone!

I have a form, I created the rules using Datanotations and it works great when I use a button or input type Submit within my form.

Validates very well!

I want to exchange this button for a link that will make the ajax call of a function of my web api, but the link does not cause validation :(

Does anyone know how to force a link to cause validation?

    using System.ComponentModel.DataAnnotations;

    namespace Framework.DTO {
        public class DadosAlteracaoSenha : BaseDTO {
            public string IdUsuario { get; set; }

            [Display(Name = "Username")]
            [Required(ErrorMessage = "Username deve ser informado.", AllowEmptyStrings = false)]
            [StringLength(50, MinimumLength = 4, ErrorMessage = "Username deve ter entre 4 à 50 caractéres.")]
            public string Username { get; set; }

            [Display(Name = "Senha Atual")]
            [Required(ErrorMessage = "Senha atual deve ser informada.", AllowEmptyStrings = false)]
            [StringLength(8, MinimumLength = 6, ErrorMessage = "Senha atual deve ter entre 6 à 8 caractéres.")]
            public string Senha { get; set; }

            [Display(Name = "Nova Senha")]
            [Required(ErrorMessage = "Nova senha deve ser informada.", AllowEmptyStrings = false)]
            [StringLength(8, MinimumLength = 6, ErrorMessage = "Nova senha deve ter entre 6 à 8 caractéres.")]
            public string NovaSenha { get; set; }

            [Display(Name = "Confirmação de Senha")]

Answer 1

Using jQuery Validation, you can do it in two ways:

.validate()

$("form").validate()

.valid()

if ($('form').valid())
{
   // Coloque sua lógica aqui
}

Make the button call one of them.
