i have model class

public class actorphonemodel     {         public int phonetypetd { get; set; }          public string phonetype { get; set; }          [stringlength(30, errormessageresourcetype = typeof(errormessage),             errormessageresourcename = "phone_number_you_entered_must_be_at_least_five_characters", errormessage = "", minimumlength = 5)]          [regularexpression(@"/^[ 0-9()+-]*$/", errormessageresourcetype = typeof(errormessage),             errormessageresourcename = "phone_number_is_invalid", errormessage = "")]         public string phonenumber { get; set; }     }

and on view 

@foreach (var phone in model.phones)                 {                     <tr>                         <td>@phone .phonetype</td>                         <td>                             @html.textboxfor(m => phone .phonenumber, new                        {                            @class = "phonenumber form-control",                            data_phonetype = @phone .phonetypetd,                            data_actorid = model.actorid,                            maxlength = "30"                        })                          </td>                     </tr>                 }

i using ajax post save changed phone number. , on text changed event of textbox want validate model

        $(".phonenumber").change(function () {             var phonetype = $(this).attr("data-phonetype");             var actorid = $(this).attr("data-actorid");             var phonenumber = $(this).val();              if (//validate model) {                  //code save phone number of phonetype             }         });

how can validate model in jquery.. have tried method form.valid() not working me.

i guess have validate jquery only, since on change of text there no server side call. , need validate 1 field can go regularexpression jquery. simpler. hope helps.
