How to use isNumeric in jquery validation?

Question

Problem with isNumeric validation with my form. $.isNumeric($('input#director').val()) does not work. I want to check if the input value is only a string, and if the user entered numbers by mistake, the label error will appear. but problem is, it is not working.

$(function() {
   $('.error').hide();
   $(".submit").click(function() {
      $('.error').hide();
      var director = $("input#director").val();
      if(director=="" || ($.isNumeric($('input#director').val()))){
     $("label#director_error").show();
     $("input#director").focus();
     return false;
  }
   }
}

Why do you repeat $('input#director').val() when you already put it in the variable director? — Barmar

try this way:

$("#btnsubmit").click(function() 
{ 
    if($('input#director').val()==="" || $.isNumeric($('input#director').val()))
    {
      alert("error");
        //your other code 
    }
});

$(function() {
   $('.error').hide();
   $(".submit").click(function() {
      $('.error').hide();
      var director = $("input#director").val();
      if(director=="" || isNumeric($('input#director').val())){
     $("label#director_error").show();
     $("input#director").focus();
     return false;
  }
   }
}

please use normal isNumeric function
