Mvc.remote Verify that the user name is duplicated

That's what the Model says.

1[Display (Name ="User name")]2[Required (errormessage ="please fill in {0}")]3[Stringlength ( -, Minimumlength =6, errormessage ="{0} length must be greater than {2} bit less than {1} bits")]4[System.Web.Mvc.Remote ("Checksellernick","Login", errormessage ="user account already exists")]
public string Loginno {get; set;}

Controller 里面这样写的

1[OutputCache (location = outputcachelocation.none, Nostore =true)]//Clear Cache2      PublicJsonresult Checksellernick (stringLoginno)3       {    4         //bool exists = _userservice.loginnoexist (Loginno);5           BOOLexists = Loginno.equals ("111111") ?true:false;6         returnJson (exists, jsonrequestbehavior.allowget);7}

That's what the View says.

1      New " Register_input " "  - " ,  }) 2 3 class="register_error"> @Html. validationmessagefor (o = O. Loginno) </div>
