Question

I would like to know, how can I call another custom validation method of jquery validate in my method to validate some data. For sample, I have a field called ‘Document ID’ that can accept CPF or CNPJ (both are brazilians documents), and I need to validate it with jquery validate. I’m doing something like this:

jQuery.validator.addMethod("cpf", function(value, element) {
   // my validation for CPF Documents
}, "CPF inválido!");

jQuery.validator.addMethod("cnpj", function(value, element) {
   // my validation for CNPJ Documents
}, "CNPJ inválido!");

Both works fine when I have one field for each type but I have only one and I have to discovery what my user type on textfield and validate it, somethind like this:

jQuery.validator.addMethod("documentoId", function(value, element) {

   if (value.lenght <= 11) {
      // validation for CPF and change the message
   }
   else if (value.lenght <= 14) {
      // validation for CNPJ and change the message
   }

}, 'Documento inválido');

but I don’t know how to call these custom functions (cpf and cnpj) inside my another function (documentId).

How can I do it? and how can I change the message inside my custom validation ?

Thank you!
Cheers!

What about this?

jQuery.validator.addMethod("documentoId", function(value, element) {

   if (value.length <= 11) {
      jQuery.validator.methods.cpf.call(this, value, element);
   }
   else if (value.length <= 14) {
      jQuery.validator.methods.cnpj.call(this, value, element);
   }

}, 'Documento inválido');

Full example changing the error message

jQuery.validator.addMethod("documento", function(value, element) {

  // remove pontuações
  value = value.replace('.','');
  value = value.replace('.','');
  value = value.replace('-','');
  value = value.replace('/','');

  if (value.length <= 11) {
    if(jQuery.validator.methods.cpf.call(this, value, element)){
      return true;
    } else {
      this.settings.messages.documento.documento = "Informe um CPF válido.";
    }

  }
  else if (value.length <= 14) {
    if(jQuery.validator.methods.cnpj.call(this, value, element)){
      return true;
    } else {
      this.settings.messages.documento.documento = "Informe um CNPJ válido.";
    }

  }

  return false;

}, "Informe um documento válido.");
