 error:function (xhr, ajaxOptions, thrownError) {
        alert(xhr.status);

in code error ajax request for catch error connect between client to server if you want show error message of your application send in success scope

such as

success: function(data){
   //   data is object  send  form server 
   //   property of data 
   //   status  type boolean 
   //   msg     type string
   //   result  type string
  if(data.status){ // true  not error 
         $('#api_text').val(data.result);
  }
  else 
  {
      $('#error_text').val(data.msg);
  }
